I am using external DAC clock. NCO phase and frquency reset using Sysref takes less time compared to SIF sync. I have a requirement of using external trigger(not a integer divider of DAC clock) for Reset . How to implement on evaluation module.

Hi Dheeraj,
You can modify the EVM by removing R103 and R104 and apply a differential external SYSREF pulse there.
The common mode of the pulse generator must be set to 500mV.
Thanks,
Eben.
