DAC37J84: LVPECL termination for Clock and Sysref

Part Number: DAC37J84
Other Parts Discussed in Thread: DAC38J82EVM


I am using DAC37J84 in my design. What is the termination circuit to be used to provide LVPECL Clock and Sysref input to the DAC? I am planning to provide ac coupled LVPECL.

Can the device take LVDS Clock and Sysref inputs?

If yes, which one gives better performance?

Clock frequency: 1GHz
