Kiran,
It is recommended to use LVPECL for both. LVDS does not guarantee a large enough differential swing for the clock input. Please see section 7 of the attached document for more information regarding this. You can also use the DAC38J82EVM schematic…
Kalyn,
To match the output impedance one would typically use a resistor network as shown in the attached document, that would be placed between the DAC and an amplifier for a DC coupled application. I have also attached a schematic example of a board…
Sam,
What do you mean by T/f? Also I could not see the attachment. I am attaching two schematics that may help you with your design.
Regards,
Jim

Hi Eknath ,
Schmitt trigger devices are recommended for slow rising inputs and SN74AUP1G14 is Schmitt trigger as well. It should be suitable for inputs from RC network circuits .The only thing to watch out for ,since there is slow rising inputs is the…
Rory,
See FMC connector J16 of the DAC37J84EVM and FMC HPCO of the ZCU102 to see how the signals are mapped between the two boards.

Sarika,
It should be 100 Ohm diff, with 50 Ohm pull downs on each leg, not pull ups, on both ends of the filter. See attached schematics for example. One has a DAC connected to a TRF3705 and the other a TRF3722 modulator. Both cases are using 50 Ohm…
