 MC10EP195, MC100EP195 3.3V ECL Programmable Delay Chip
The MC10/100EP195 is a Programmable Delay Chip (PDC) designed primarily for clock deskewing and timing adjustment. It provides variable delay of a differential NECL/PECL input transition. http://onsemi.com The delay section consists of a programmable matrix of gates and multiplexers as shown in the logic diagram, Figure 3. The delay increment of the EP195 has a digitally selectable resolution of about MARKING DIAGRAM* 10 ps and a net range of up to 10.2 ns. The required delay is selected by the 10 data select inputs D[9:0] values and controlled by the LEN (pin 10). A LOW level on LEN allows a transparent LOAD mode of MCXXX real time delay values by D[9:0]. A LOW to HIGH transition on LEN EP195 will LOCK and HOLD current values present against any subsequent AWLYYWWG changes in D[10:0]. The approximate delay values for varying tap 32 LQFP-32 numbers correlating to D0 (LSB) through D9 (MSB) are shown in FA SUFFIX Table 6 and Figure 4. 1 CASE 873A Because the EP195 is designed using a chain of multiplexers it has a fixed minimum delay of 2.2 ns. An additional pin D10 is provided for controlling Pins 14 and 15, CASCADE and CASCADE, also latched by LEN, in cascading multiple PDCs for increased programmable 1 range. The cascade logic allows full control of multiple PDCs. MCXXX 1 32 Switching devices from all "1" states on D[0:9] with SETMAX LOW EP195 QFN32 AWLYYWWG to all "0" states on D[0:9] with SETMAX HIGH will increase the MN SUFFIX G delay equivalent to "D0", the minimum increment. CASE 488AM Select input pins D[10:0] may be threshold controlled by combinations of interconnects between VEF (pin 7) and VCF (pin 8) XXX = 10 or 100 for LVCMOS, ECL, or LVTTL level signals. For LVCMOS input A = Assembly Location levels, leave VCF and VEF open. For ECL operation, short VCF and WL, L = Wafer Lot VEF (Pins 7 and 8). For LVTTL level operation, connect a 1.5 V YY, Y = Year supply reference to VCF and leave open VEF pin. The 1.5 V reference WW, W = Work Week G or G = Pb-Free Package voltage to VCF pin can be accomplished by placing a 2.2 kW resistor (Note: Microdot may be in either location) between VCF and VEE for a 3.3 V power supply. *For additional marking information, refer to The VBB pin, an internally generated voltage supply, is available to Application Note AND8002/D. this device only. For single-ended input conditions, the unused differential input is connected to VBB as a switching reference voltage. ORDERING INFORMATION VBB may also rebias AC coupled inputs. When used, decouple VBB See detailed ordering and shipping information in the package and VCC via a 0.01 mF capacitor and limit current sourcing or sinking dimensions section on page 17 of this data sheet. to 0.5 mA. When not used, VBB should be left open.

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit values are applied individually under normal operating conditions and not valid simultaneously. 20. Measured using a 750 mV source, 50% duty cycle clock source. All loading with 50 W to VCC - 2.0 V. 21. Specification limits represent the amount of delay added with the assertion of each individual delay control pin. The various combinations of asserted delay control inputs will typically realize D0 resolution steps across the specified programmable range. 22. Duty cycle skew guaranteed only for differential operation measured from the cross point of the input to the cross point of the output. 23. This setup time defines the amount of time prior to the input signal the delay tap of the device must be set. 24. This setup time is the minimum time that EN must be asserted prior to the next transition of IN/IN to prevent an output response greater than 75 mV to that IN/IN transition. 25. This hold time is the minimum time that EN must remain asserted after a negative going IN or positive going IN to prevent an output response greater than 75 mV to that IN/IN transition. 26. This release time is the minimum time that EN must be deasserted prior to the next IN/IN transition to ensure an output response that meets the specified IN to Q propagation delay and transition times. 27. The monotonicity indicates the increasing delay value for each binary count increment on the control inputs D[9:0].

Figure 5. AC Reference Measurement
Cascading Multiple EP195s To increase the programmable range of the EP195, internal cascade circuitry has been included. This circuitry allows for the cascading of multiple EP195s without the need for any external gating. Furthermore, this capability requires only one more address line per added E195. Obviously, cascading multiple programmable delay chips will result in a larger programmable range: however, this increase is at the expense of a longer minimum delay.
Figure 6 illustrates the interconnect scheme for cascading two EP195s. As can be seen, this scheme can easily be expanded for larger EP195 chains. The D10 input of the EP195 is the CASCADE control pin. With the interconnect scheme of Figure 6 when D10 is asserted, it signals the need for a larger programmable range than is achievable with a single device and switches output pin CASCADE HIGH and pin CASCADE LOW. The A11 address can be added to generate a cascade output for the next EP195. For a 2-device configuration, A11 is not required.

An expansion of the latch section of the block diagram is pictured in Figure 7. Use of this diagram will simplify the explanation of how the cascade circuitry works. When D10 of chip #1 in Figure 6 is LOW this device's CASCADE output will also be low while the CASCADE output will be high. In this condition the SET MIN pin of chip #2 will be asserted HIGH and thus all of the latches of chip #2 will be reset and the device will be set at its minimum delay. Chip #1, on the other hand, will have both SET MIN and SET MAX deasserted so that its delay will be controlled entirely by the address bus A0--A9. If the delay needed is greater than can be achieved with 1023 gate delays (1111111111 on the A0--A9 address bus) D10 will be asserted to signal the need to cascade the delay to the next EP195 device. When D10 is asserted, the SET MIN pin of chip #2 will be deasserted and SET MAX pin asserted resulting in the device delay to be the maximum delay. Table 13 shows the delay time of two EP195 chips in cascade. To expand this cascading scheme to more devices, one simply needs to connect the D10 pin from the next chip to the address bus and CASCADE outputs to the next chip in the same manner as pictured in Figure 6. The only addition to the logic is the increase of one line to the address bus for cascade control of the second programmable delay chip.

Multi-Channel Deskewing
The most practical application for EP195 is in multiple channel delay matching. Slight differences in impedance and cable length can create large timing skews within a high-speed system. To deskew multiple signal channels, each channel can
be sent through each EP195 as shown in Figure 8. One signal channel can be used as reference and the other EP195s can be used to adjust the delay to eliminate the timing skews. Nearly any high-speed system can be fine-tuned (as small as 10 ps) to reduce the skew to extremely tight tolerances.

Figure 8. Multiple Channel Deskewing Diagram Measure Unknown High Speed Device Delays
EP195s provide a possible solution to measure the unknown delay of a device with a high degree of precision. By combining two EP195s and EP31 as shown in Figure 9, the delay can be measured. The first EP195 can be set to SETMIN and its output is used to drive the unknown delay device, which in turn drives the input of a D flip-flop of EP31. The second EP195 is triggered along with the first EP195 and its output provides a clock signal for EP31. The programmed delay of the second EP195 is varied to detect the output edge from the unknown delay device.
CLOCK CLOCK EP195 IN IN #1 Q Q
If the programmed delay through the second EP195 is too long, the flip-flop output will be at logic high. On the other hand, if the programmed delay through the second EP195 is too short, the flip-flop output will be at a logic low. If the programmed delay is correctly fine-tuned in the second EP195, the flip-flop will bounce between logic high and logic low. The digital code in the second EP195 can be directly correlated into an accurate device delay.
