FUNCTIONAL DESCRIPTION CDS Circuit
The clamp circuit clamps the feed-through level of the CCD signal with the A pulse. Then the fl/H1 circuit samples the signal period of the one with the fl/H1 pulse and holds on. Thus the video signal is obtained. But this signal has a level drop caused by the reset pulse of the CCD signal, and for removing it, the fl/H2 circuit samples this signal again with the fl/H2 pulse. For reducing the effect of the sampling pulse or other noise sources, the CDS circuit is formed with a differential structure.
Blanking Circuit
The output signal is fixed to the blanking level with the O pulse. The blanking level is the sum of the black level and the offset value decided by the value of the OFFSET serial register.
A/D Converter Circuit
The fl/H3 circuit samples the amplified signal with the fl/H3 pulse and the A/D converter converts the sampled signal to 10-bit straight binary digital data. The clamp circuit placed in front of the A/D converter clamps the signal level beside the lower limit of the convertible input range with the A pulse. The clamped level is controllable by the voltage of the ADOFS pin. The A/D conversion is executed at the rising edge of the ADCK clock, and the data is output at the falling edge. The high level voltage of the outputs is controlled by the voltage of the VLOGIC pin.
Bias Error Amplifier Circuit
For stabilizing the bias level of the CDS circuit and reducing the offset of the AGC circuit, the bias error amplifier acts with the I pulse during the OPB period.
AGC Amplifier Circuit
The AGC amplifier amplifies the video signal obtained by the CDS circuit. The gain of the AGC is controlled by the value of the AGCGAIN serial register. And the maximum gain of the AGC is controlled by the value of the GAINSEL serial register.
Standby Function
By making the pin low, all actions of this IC stop and power consumption is decreased. The outputs of the A/D converter (DO0 to DO9) turn to high impedance when on standby.
OPB Clamp Circuit
For clamping the level of the amplified signal to the black level, the OPB clamp circuit acts with the I pulse during the OPB period.

IR3Y38M
Serial Interface Circuit
The IR3Y38M has a serial interface to control the gain of the AGC amplifier and the offset of the blanking level. This interface is constituted by a shift register for serial-parallel conversion, data registers and D/A converters. The data input to SDATA is fetched and shifted at
SDATA SCK Shift Register Store D2-D9 D0 D1 Decoder Select
the rising edge of the SCK. While transmitting data, the SDATA must be low when the SCK falls. When the SDATA is high and the SCK falls, the data on the shift register is stored at the selected data register at the following falling edge of the SDATA. The stored data register is selected by the data of the D0 and D1 bits.

PRECAUTIONS
Each VCC1 to VCC6 pin corresponds to the each GND1 to GND6 pin. Connect a ceramic capacitor as near the IC as possible between each corresponding VCC pin and GND pin. The GND1 pin is the ground of the CDS/ADC circuit handling a weak signal. Pay careful attention to the board layout of the GND1 pattern in order to avoid the potential fluctuation of the GND1 caused by the current of the other GND pins. Especially pay attention to the current of the GND6 pin's flowing spiky current. All the GND pins must be at the same potential and not open. And keep the potential difference of each VCC pin within 0.3 V. The high level voltage of the outputs of the A/D converter is controllable by the voltage of the VLOGIC pin, but take care that the high level voltage does not fall below about 1.5 V, in spite of making the VLOGIC pin 0 V. This may cause the latch up of the following logic ICs if the power supply of this IC rises up faster than the power supply of the following logic. To avoid this problem, it is recommended to make the pin low until the voltage of the logic power supply becomes stable. Take care too that the high level voltage does not rise above about VCC - 1.0 V, in spite of making the VLOGIC pin the VCC potential. Restore the value of the serial register when setting up the power supply or making the pin high because the value will have been removed in that case.

PARAMETER SYMBOL CONDITIONS (GAIN SEL) = 0, (AGC GAIN) = 0 A = SG2, I = SG3 Bandwidth (1) (Minimum gain) fTN Input the SG1 (f = 2 MHz, V = 0.2 Vp-p) to the SIN and measure the amplitude of the AGCOUT. Increase the frequency and measure the frequency when the amplitude attenuates to -3 dB. (GAIN SEL) = 7, (AGC GAIN) = 255 A = SG2, I = SG3 Bandwidth (2) (Maximum gain) fTX Input the SG1 (f = 2 MHz, V = 8 mVp-p) to the SIN and measure the amplitude of the AGCOUT. Increase the frequency and measure the frequency when the amplitude attenuates to -3 dB. (GAIN SEL) = 0, (AGC GAIN) = 0 SIN = GND1, (OFFSET) = 0, A = 0 V, OFFSET adjustment limit (1) (OFFSET = 0) I=0V Measure the voltage of the AGCOUT at BLK = 3.3 V and define it VBO11. Measure the one similarly at BLK = 0 V and define it VBO12. VBON = VBO12 - VBO11 (GAIN SEL) = 0, (AGC GAIN) = 0 OFFSET adjustment limit (2) (OFFSET = 63) SIN = GND1, (OFFSET) = 63, A = 0 V, VBOX I=0V Measure the VBO21 and VBO22 similarly to above-mentioned method. VBON = VBO22 - VBO21 (GAIN SEL) = 0, (AGC GAIN) = 0 A = SG2, I = SG3 VDYN Input the SG1 (f = 2 MHz, V = 0.9 Vp-p) to the SIN and measure the amplitude of the AGCOUT. (GAIN SEL) = 7, (AGC GAIN) = 255 A = SG2, I = SG3 Input the SG1 (f = 2 MHz, V = 50 mVp-p) to the SIN and measure the amplitude of the AGCOUT. 2.0 2.2 - Vp-p 50 65 - mV 13 20 - MHz 24 35 - MHz MIN.

* A/D Converter Circuit (Unless otherwise specified, TA = +25 C, VCC1 = VCC2 = VCC3 = VCC4 = VCC5 = VCC6 = 5.0 V, VLOGIC = 3.3 V, ADCK = 18 MHz square wave, = 0 V, = 0 V, = 3.3 V, A = 3.3 V, fl/H1 = 0 V, fl/H2 = 0 V, fl/H3 = 0 V, O = 3.3 V, I = 3.3 V, SW42 = OFF, SW43 = (b), A = 3.3 V)
PARAMETER SYMBOL SW43 = (a) A=0V ADCIN = GND4 Read the output value of DO0 to DO9. Clamp value adjustment limit (1) Clamp value adjustment limit (2) Differential linearity error Integral linearity error SW42 = ON, V42 = 5.0 V, A = 0 V, DCLPN ADCIN = GND4 Read the output value of DO0 to DO9. DCLPX SW42 = ON, V42 = 1.6 V, A = 0 V, ADCIN = GND4 Read the output value of DO0 to DO9. DLE ADCIN = SG4 Read the output value of DO0 to DO9 at about 10 times and make it a histogram. Normalize the histogram and obtain the DLE. Integrate the histogram and obtain the ILE. Propagation delay (L/H) ADCIN = SG4, CL = 20 pF Measure the delay time from the falling edge (50%) of the ADCK to the rising edge (50%) of the DO0 to DO9. ADCIN = SG4, CL = 20 pF Propagation delay (H/L) tDHL Measure the delay time from the falling edge (50%) of the ADCK to the falling edge (50%) of the DO0 to DO9. ADCIN = SG4, CL = 20 pF Output rise time tWLH Measure the rise time (10%/90%) of the DO0 to DO9. ADCIN = SG4, CL = 20 pF Output fall time tWHL Measure the fall time (90%/10%) of the DO0 to DO9. 10 17 25 ns 10 17 25 ns 15 26 38 ns
