NOTES: 1. 2. Absolute maximum rating indicates the limit beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is functional but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the electrical characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. VCC supply pins 11, 13, and 22 must be externally wired together to prevent internal damage during VCC power on/off cycles. The supply current specified is the quiescent current for VCC1/VCC2 and VCC3 with RL = , The supply current for VCC2 (pin 22) also depends on the output load. Output voltage is dependent on load resistor. Test circuit uses RL = 470 Measure gain difference between any two amplifiers Vin = 700mVpp. When measuring video amplifier bandwidth or pulse rise and fall times, a double sided full ground plane printed circuit board without socket is recommended. Video amplifier 50MHz cross talk test also requires this printed circuit board. The reason for a double sided full ground plane PCB is that large measurement variations occur in single sided PCBs. Adjust input frequency from 10MHz (AV max reference level) to the -3dB frequency (f -3dB). Measure output levels of the other two undriven amplifiers relative to the driven amplifier to determine channel separation. Terminate the undriven amplifier inputs to simulate generator loading. Repeat test at fin = 50MHz for cross talk 50MHz. A minimum pulse width of 200 ns is guaranteed for a horizontal line of 15kHz. This limit is guaranteed by design. if a lower line rate is used a longer clamp pulse may be required. During the AC test the 4V DC level is the center voltage of the AC output signal. For example. If the output is 4Vpp the signal will swing between 2V DC and 6V DC. These parameters are not tested on each product which is controlled by an internal qualification procedure. The conditions block's 03, 04, 05... etc. signify sub address' 0F03, 0F04, 0F05... etc. Sub address 0F03, 0F05 ~ 0F07: FFH 0F04, 0F08 ~ 0F0C: 80H RGB input = S1, When the ABL input voltage is 0V, the R/G/B's output voltage is VR/VG/VB and uses the formula ABLR = 20log (VR/VcffR) OSD TST mode = High, CLP operation off, RGB input = S5 (frequency sweep), RGB input clamp cap = 2.1V DC, RGB clamp cap (pin 23/20/17) = Vcap voltage (7.0V), S5's frequency 1MHz 130MHz sweep, -3dB point = 20log (V130MHz/V1MHz) 03, 05 ~ 07: FFH 04, 08 ~ 0C: 80H 0F: 80H OSD TST mode = High, CLP operation off, RGB input clamp cap = 2.1V DC, RGB clamp cap (pin 23/20/17) = Vcap voltage (7.0V), 03, 05 ~ 07: FFH 04, 08 ~ 0C: 80H 0F: 80H R input = S5 (50MHz) CT_50M = 20log (VoutG/VoutR) or 20log (VoutB/VoutR) OSD TST mode = High, CLP operation off, RGB input clamp cap = 2.1V DC, RGB clamp cap (pin 23/20/17) = Vcap voltage (7.0V), 03, 05 ~ 07: FFH 04, 08 ~ 0C: 80H 0F: 80H R input = S5 (130MHz) CT_150M = 20log (VoutG/VoutR) or 20log (VoutB/VoutR)

FUNCTIONAL DESCRIPTIONS
DATA TRANSMISSION The interface between S1D2502A01 and MCU follows the I2C protocol. After the starting pulse, the transmission takes place in the following order: Slave address with R/W bit, 2-byte register address, 2-byte data, and stop condition. an acknowledge signal is received for each byte, excluding only the start/stop condition. The 2-byte register address is composed of an 8-bit row address, and an 8-bit column address. The order of transmission for a 2-byte register address is 'Row address Column address'. The 2 bytes of data is because S1D2502A01 has a 16-bit base register configuration. S1D2502A01's slave address is BAh. It is BBh in read mode, and BAh in write mode. * Address Bit Pattern for Display Registers Data (a) row address bit pattern R3 - R0: Valid data for row address A15 X A14 X A13 X A12 X A11 R3 A10 R2 A9 R1 A8 R0
(b) Column address bit pattern C4 - C0: Valid data for column address A7 X X:Don't care bit A6 X A5 X A4 C4 A3 C3 A2 C2 A1 C1 A0 C0

Figure 9. Memory Map of Display Registers
The display RAM's address of the row and column number are assigned in order. The display RAM is composed of 4 register groups (character & attribute register, row attribute register, frame control register, and V-AMP control register). The display area in the monitor screen is 30 column x 15 row, so the related character & attribute registers are also 30 column x 15 row. Each register has a character address and characteristics corresponding to the display location on the screen, and one register is composed of 16 bits. The lower 9 bits select the font from the 448 ROM fonts, and the upper 7 bits give font characteristics to the selected font. The row attribute register takes up the display RAM's 31st column. It provides raster color, raster color intensity, character color intensity, horizontal & vertical character size, box, border, and shadow features in units of row. The frame control registers are in the 16th row. It controls OSD's display location, character height, scroll, and fade-in/out in units of frame. The V-AMP control registers are also located in the 16th row.

Table 11. Register Description Registers Character & Attribute Registers (Row 00 -- 14, Column 00 -- 29) Bits C8 -- C0 (Bit 8 -- 0) Blink/FINT (Bit 9) Description Character code address This is the address of 448 ROM fonts. Character blinking/font intensity If row attribute register's INTE bit is set to '1', this bit carries out the font intensity feature, and if not, the character blinking feature instead. In other words, to carry out character blinking, set the INTE bit to '0'. Select frame control register-0's BliT bit as blinking time, and select Bli1, Bli0 Bit as blinking duty. When giving intensity in units of font, refer to the table below.

As shown above, the horizontal character size is decided by using these two bits in combination. However, unlike VZ, the surrounding area (row) is taken over in the amount of the HZ increase, so you must keep that in mind when changing font size. Refer to Character Size. CINT (Bit 4) Character color intensity When this bit is set to '1', the color intensity of the character on the same row becomes high. Refer to BLINK/FINT, INTE, RINT, and CINT's combination chart in the previous page. (Even if you change this bit, you can't check the intensity feature on the demo board. This is because the OSD IC's output INT is applied as the video Pre Amp's input, and the demo board doesn't apply the OSD IC's INT output to the Pre Amp.) Raster color intensity When this bit is set to '1', the color intensity of the raster on the same row becomes high. Refer to BLINK/FINT, INTE, RINT, and CINT's combination chart in the previous page. (Like CINT given above, you can't check RINT's feature on the demo board.)

Table 11. Register Description (Continued) Registers Row Attribute Registers (Row00 -- 14, Column30) Bits RB, RG, RR (Bit 8 -- 6) Description Raster color is determined by these bits The raster color is chosen from out of 16 colors using these 3 bits and the row attribute register's 'RINT' bit. If 'BOXE' Bit is not '1', the setting of these three bits have no meaning. Refer to 'BOXE' bit shown below. Character shadowing Character shadowing feature is carried out if you set this bit to '1'. Character bordering Character bordering feature is carried out if you set this bit to '1'. BOX enable If you set this bit to '1', it uses the character & attribute register's 'BINV', 'BOX1', and 'BOX0' bits to carry out box drawing, and if you set it to '0', the character & attribute register's bits F~D (BINV, BOX1, BOX0) act as each raster color's B, G, and R. This has higher priority than selection by setting RB, RG, and RR bits. In other words, if the BOXE bit is set to '0', the character & attribute register's BINV, BOX1, and BOX0 each do the function of RB, RG, and RR to decide the raster color, and the original row attribute register's RB, RG, and RR don't do anything. Color blink enable If this bit is '1', the color blinking effect is applied. Color blinking is instead of normal blinking, 8 colors appear in order in the font's character part. Its time and duty is controlled by 'BliT', 'Bli1', and 'Bli0', like in character blinking. Intensity enable Refer to the table on the combination of BLINK/FINT, INTE, RINT, and CINT bits in the explanation of the character & attribute register's BLINK/ FINT bit. Back raster enable If the BREN bit is '1' and the raster color is black, the raster is transparent. That is, the video back raster is shown. If not, the OSD raster covers the video's back raster. Refer to other color effect. Reserved

Table 11. Register Description (Continued) Registers Frame Control Registers -- 0 (Row 15, Column 00) Bits BliT (Bit 0) Bli1, Bli0 (Bit 2 -- 1) Description Blink time control If this bit is '1', blink time is 0.5sec, and if not, 1sec. Blinking duty control As the font blinks, there is a time when it is visible and invisible on screen. Blinking duty is the ratio of the invisible time to the visible time, and is decided by the combination of these two bits. In other words, blinking duty is the length of time the font is shown on screen.

Blink Off Duty 25% Duty 50% Duty 75%
Scroll time control If this bit is '1', scroll time is 0.5sec, and if not, 1sec. Scroll enable Scrolling effect is controlled by this bit. If this bit is `1', scrolling effect is enabled. You must remember that scrolling can be turned on/off only when OSD is enabled/disabled. OSD enable OSD is enabled when this bit is '1'. In other words, if this bit isn't '1'OSD is not output inspite of writing control data. We recommend that you enable the OSD after setting the control registers (such as the character & attribute register) because of video and OSD output timing. RAM erasing If this bit is '1', the RAM data (character & attribute registers and row attribute registers) is erased. The time spent in carrying out this operation is called erasing time, which can be calculated as follows. Erasing time = RAM clock x 480 (RAM cell no.) RAM clock = 12 dot clock Dot clock = 1/(dot frequency) Dot frequency = Horizontal frequency x resolution (mode) Therefore, the maximum erasing time value is: (Erasing Time)MAX = (12 x 480) / (15k x 320) = 1.2ms

Table 11. Register Description (Continued) Registers Frame Control Registers -- 0 (Row 15, Column 00) Bits HPOL (Bit B) VPOL (Bit C) FdeT (Bit D) Fde (Bit E) Description Polarity of horizontal fly back signal If this bit is '1', HFLB's polarity is positive, and if '0', it is negative. In other words, this bit is set to '1' if active high, and '0' if active low. Polarity of vertical fly back signal If this bit is '1', VFLB's polarity is positive, and if '0', it is negative. In other words, this bit is set to '1' if active high, and '0' if active low. Fade-in and fade-out time control If this bit is '1', fade-in/fade-out time is 0.5sec. If not, it is 1sec. Fade-in and fade-out enable This feature is enabled when this bit is '1'. The effect where the display goes from the center to the outside, or from the outside to the center in units of font, is called fade-in/fade-out. Refer to fade-in/fade-out. You must remember that fade-in/fade-out, like scrolling on/off, only occurs when OSD enabled/disabled. Reserved.
Bit F
The purpose of bits 'HPOL', and 'VPOL' is to provide flexibility when using the S1D2502A01 IC. No matter which polarity you choose for the input signal, the IC will handle them identically, so you can select active high or active low according to your convenience.

Tabel 4. Register Description (Continued) Registers Frame Control Registers -- 1 (Row 15, Column 01) Bits CH5 -- CH0 (bit 5 -- 0) Description Character height control While the purpose of VZ[1:0] (vertical character height) is to control the absolute size of the character, the purpose of CH[5:0] (Character Height) is to output OSD of a uniform size even if the resolution changes. If you adjust the value in the range of CH = 18 -- CH = 63, each line's repeating number is decided (standard height CH = 18 is the reference value), by which the line is repeated. For more information on repeating number selection, refer to character height. Selection of the FBLK output pin's configuration Unlike pin description's FBLK, if this bit is '0', the FBLK pin output is high while the character and raster are being displayed and the character and raster are output as they are. If this bit is '1', the FBLK pin output becomes high only when character is being displayed, so only the character is output. Refer to 'Figure 11. Character/raster signal part.

0 1 0 1
320 dots/line 480 dots/line 640 dots/line 800 dots/line
As shown above, the number of dots per horizontal line is decided by a combination of these two bits. HF2--HF0 (bit C -- A) Horizontal frequency PLL's horizontal frequency is decided by the combination of these 3 bits. This is related to the selection of DOT[1:0], so you can't numerically express the frequency range with only the HF[2:0] selection. For more information, please refer to HF Bits Selection. Full range PLL If this bit is '1', the OSD_PLL block's VCO operates at full range (4.8MHz 96MHz). If it is '0', it operates within the region decided by the HF bit [C:A] explained above. if you can't optimize OSD screen decided by the HF bit in the high region, you may set the FPLL bit to `1'.

For facilitating internal calculations, addressing is done using exponents of 2, and the rows to the right of the 'Row Attribute Registers', excepting only IFF(255), are 'Virtual Registers' that are not used. If you set 'Frame Control Register 0's 'Erase' bit to '1', 480 areas are erased (excepting only the 16th line) in the Figure above, and the 'Erasing Time' is measured with 480 areas as the standard.

COLORING If you have an Intensity feature, the number of possible colors you can express becomes doubled. In other words, the number of colors you can represent with three colors blue, green, and red is 8 ( = 23), but with the intensity feature, it is 16 ( = 24). * Character Color Character color is assinged for each font, and the 4 components for expressing a color are listed below. Blue Green Red Intensity Character & attribute register's B bit[C] Character & attribute register's G bit[B] Character & attribute register's R bit[A] Character & attribute register's BLINK/FINT bit[9] Row attribute register's INTE bit[D] Row attribute register's CINT bit[4] If all 3 bits are set to '1', the character intensity feature is enabled.
*
Raster Color Blue Green Red Row attribute register's RB bit[8] if the row attribute register's 'BOXE' bit is '1', and character & attribute register's 'BINV' bit[F] if BOXE' bit is '0'. Row attribute register's RG bit[7] if row attribute register's 'BOXE' Bit is '1', and character & attribute register's 'BOX1' bit[E] if 'BOXE' bit is '0'. Row attribute register's RR bit[6] if row attribute register's 'BOXE' bit is '1', and character & attribute register's 'BOX0' bit[D] if 'BOXE' bit is '0'. Character & attribute register's BLINK/FINT bit[9] Row attribute register's INTE bit[D] Row attribute register's RINT bit[5] If all 3 bits are set to '1', the raster intensity feature is enabled.
Intensity
According to the 'BOXE' bit setting, raster color can be assigned in units of font or row. There is a trade-off in either case. If 'BOXE' Bit is set to '1', the box drawing feature can be carried out in units of font, but the raster color can only be assigned in units of row. On the other hand, if 'BOXE' bit is set to '0', the box drawing feature can't be carried out, but you can assign raster color in units of font. Notes for When Making S1D2502A01 Fonts Address 000h is appointed as blank data. RAM's initial values are all 0, and all bits are written as 0 when you erase the RAM, so blank data means the initial value. In other words, blank data means 'do nothing'. You don't need to write any data for the space font, except for 000h. It just needs to be an undotted area.

Other Color Effet The row attribute register's 'BREN' bit's function is shown in the Figure below. If you set the 'BREN' bit of the row with the letter A as '0' after selecting A and B's raster color as black, the raster color black will be displayed. But if you set the 'BREN' bit of the row with the letter B as '1', the raster color black becomes invisible, so the back raster color (gray) is displayed as if it is the raster color.
BREN bit = 0 & Rastor Color = Black Gray
BREN bit = 1 & Rastor Color = Black
BREN bit = 1 & Rastor Color = Light Blue
Figure 14. Color Effect by BREN Bit Color blinking is using a selective control bit in blink mode to replace normal blinking with 8 different colors appearing in order on the font's character. Color blinking only replaces normal blinking, and blink time and blink duty are still applied at the same time. Therefore, if the blink duty is not set to off, only 3 ~ 4 colors may appear according to the blink duty, instead of all 8.
SIZING/POSITIONING * Character Size Row attribute register's HZ bit[3:2] and VZ bit[1:0] control the character's vertical and horizontal size by factors of 1/2/3/4 in units of row. VZ is correctly expressed without regard to size since the next line is just pushed down in order, but HZ decides the column that the font occupies according to the size. For example, if HZ [1:0] = 0, 1, the font doubles in the horizontal direction, and one font takes up 2 columns. Therefore, the column address must move in the same amount as the HZ for the next font to be expressed correctly. in other words, if the horizontal size is doubled and takes up 2 columns, the next font must be put 2 columns back.

Character Height Whereas the purpose of VZ[1:0] (Vertical Character Height) is to adjust the character's absolute size, the purpose of CH[5:0] (Character Height) is to output a uniformly sized OSD even if the resolution changes. To express a Character Height of CH = 18 ~ CH = 63 after receiving CH[5:0]'s input from the frame control register-1, decide on each line's repeating number (Standard Height CH = 18) and repeat the lines. The following Figure shows two examples of a height-controlled character. height control is carried out by repeating some of the lines.

Repeating line-number can be found by the following formula. [# of the repeating lines = 2 + N x M], where N = 1, 2, 3, ... and M = round{14 / (CH[5:0]-18)}. 1. If CH[5:0] is greater than 32 and less than or equal to 46 (32 < CH[5:0] 46), all lines are repeated once or twice. The lines that are repeated twice are chosen by the following formula. [# of the repeating lines = 2 + N x M], where N = 1, 2, 3, ... and M = round {14 (CH[5:0]-32)}. 2. If CH[5:0] is greater than 46 and less than or equal to 60 (46 < CH[5:0] 60), all lines are repeated two or three times. The lines that are repeated three times are chosen by the following formula. [# of the repeating lines = 2 + N x M], where N = 1, 2, 3, ... and M = round {14 (CH[5:0]-46)}. 3. If CH[5:0] is greater than 60 and less than or equal to 64 (60 < CH[5:0] 64), all Lines are repeated three or four times. The lines that are repeated four times are chosen by the following formula. [# of the repeating lines = 2 + N x M], where N = 1, 2, 3, ... and M = round {14 (CH[5:0]-60)}. CH's reference value is 18, and even if you input 0, it operates in the same way as when CH = 18. The repeating line-number is limited to 16. If the M value is less than or equal to 1, all lines of the standard font are repeated more than once. Table 13.

Fade-In/Fade-Out Fade-in/fade-out is displaying from the center to the outside in units of font when OSD display is on/off. Each font's display is turned on/of without regard to size, in units of (12 x 18) dot. Also, to control the fade in/out time, the V_PULSE's 1/4, 1/8 clocks are used for counting. In other words, as control data, it takes 0.5sec if the frame control register - 0's 'FdeT' bit is 1, and 1sec if 0. If it is difficult to visualize the fade-in / fade-out feature with the explanation and diagrams in this document, write the control data to the OSD IC and verify the IC's operations. Like the scrolling feature, fade in/out can only be verified when OSD is enabled/disabled.

PLL CONTROL * Introduction PLL (Phase Lock Loop) is feedback controlled circuit that maintains a constant phase difference between a reference signal and an oscillator output signal. Generally, PLL is composed as follow Figure.
Reference Signal PFD (Phase Frequency Detector) LF (Loop Filter) VCO (Voltage Controlled Oscillator)
FD (Frequency Detector)
Figure 22. Block Diagram of General PLL
- PFD (Phase Frequency Detector) PFD compares the phase of the VCO output frequency, with the phase of a reference signal frequency output pulse is generated in proportion to that phase difference. - LF (Loop Filter) LF smooths the output pulse of the phase detector and the resulting DC component is the VCO input. - VCO (Voltage Controlled Oscillator) VCO is controlled by loop filter output. The output of the VCO is fed back to the phase frequency detector input for comparison which in turn controls the VCO oscillating frequency to minimize the phase difference. - FD (Frequency Divider) FD divides too much different frequency that is oscillated from the VCO to compare it with reference signal frequency.

- VCO (Input) Error signal that passes through an external loop filter is input into VCO. Operation voltage range is 1-4V. You can raise immunity towards external noise by lowering VCO sensitivity. You can do this by making it have the maximum operation voltage range possible in the 5V power voltage.

After fixing time constants of the external circuit and PLL control bits except HF bits, if HF bits are stepped up, the voltage measured at pin-3 drops. On the contrary, if HF bits are stepped down, the voltage rises. The voltage measured at pin-3 don't change by changing CP bits.

External Register at pin-4
The external register at pin-4 is the factor that changes greatly at PLL tunning. The initial value of this external register value is decided as follows. At first, the external register is replaced variable-register (about 50K range). and then, set the lowest PLL control bits at the lowest frequency allowed by set. and then, change variable-register to be 2.35V that optimum voltage is locking. and then, measure register value at this time. also, set the highest PLL control bits at the highest frequency allowed by set. and then, change variable-register to be 2.35V that optimum voltage is locking. and then, measure register value at this time. You may decide the average of these two registers' value to initial value.

RECOMMENDATION
5V Power Routing S1D2502A01's OSD part power is composed of analog VDD and digital VDD. To eliminate clock noise influence in the digital block, you need to separate the analog VDDA and digital VDD. (BD102 use: Refer to Application Circuit ) 12V Power Routing Because S1D2502A01 is a wideband AMP of above 150MHz, 12V power significantly affects the video characteristics. The effects from the inductance and capacitance are different for each board, and , therefore, some tuning is required to obtain the optimum performance. The output power, VCC2, must be separated from VCC1 and VCC3 using a coil, which is parallel-connected to the damping resistor.The appropriate coil value is between 20uH - 200uH. Parallel-connected a variable resistor to the coil and control its resistance to obtain the optimum video waveform. (Moreover, BD103 can tune using a coil and variable resistor to obtain the optimum video waveform. L103, R124, BD103: Refer to application circuit) VCC1, VCC3 12V Power Use a 104 capacitor and large capacitor greater than 470uH for the power filter capacitor. 12V Output Stage Power VCC2 Do not use the power filter capacitor. 5V Digital Power VDD Don't use a coil or magnetic core to the VDD input. Make the power filter capacitor, an electric capacitor of greater than 50uF, single and connect it to VSS, the digital GND. Output Stage GND2 Care must be taken during routing because it ,as an AMP output stage GND, is an important factor of video oscillation. R/G/B clamp cap and R/G/B load resistor must be placed as close as possible to the GND2 pin. GND2 must be arranged so that it has the minimum GND loop, which at one point must be connected to the main GND. Digital GND VSS When this is to be connected directly to the GND2, it can cause the OSD clock noise, so the loop connection should be routed as far away as possible. If the OSD clock noise affects the screen, separate VSS GND from all GND and connect it to the main board using a bead. Again, the bead connection point should be placed as far away as possible to the GND2. Analog Block The PLL built in to S1D2502A01 is sensitive to noise due to the wide range PLL characteristics. Therefore, you need to isolate the analog block in the following manner. First make a separate land for the analog block (pin2 pin6)'s ground, and connect it to the main ground through a 1M resistor. The analog GND of both sides of a double faced PCB must be separated from the main ground. (Separate pin 2's 5V analog GND, which is the GND for OSD PLL, from the main and digital GNDs and connect it to the main GND using about 1M resistor. GND for pins 2 - 6 is the No. 2 VSSA GND.)

Preliminary VIDEO AMP MERGED OSD PROCESSOR FOR MONITORS
I2C Control Line (SCL, SDA Line) I2C communication noise (noise generated in the OSD display pattern when data is transmitted in the I2C line) may be generated because of an I2C control line that passes near the analog block. The I2C control lines near S1D2502A01 must be separated from the analog block as much as possible. Furthermore, the I2C bus interference can be prevented by inserting a series resistor in the line. Horizontal Flyback Signal Display jittering can be generated if the horizontal signal (HFLB) input to S1D2502A01 is not a clean signal. We recommend a short path and shielded cable for obtaining a clean signal. Generally, the input horizontal signal (HFLB) is generated by using a high voltage horizontal flyback signal. The effect from the high voltage flyback signal can be reduced by separating the R115 and R117 GND, which determines the flyback signal slice level, from the transistor GND, which generates the actual S1D2502A01 input horizontal signal. Furthermore, the flyback signal sharpness must be maintained by minimizing the values of R115, R116 and R117 resistors, which set the horizontal signal slice level. values. (R115, R116, R117: Refer to application circuit ) HFLB Input Signal Generator You can correct the circuit by reducing the resistors that sets the slice level of the horizontal signal in the HFLBgenerating circuit.
