Hi Diego,

Looking at the schematics (we do not have the board, at least yet) SYNC IN is a pulse to synchronize PLL phase between boards, for external reference you should use CLK IN or Ext ref in.

Cheers,
Kaj

Hi everyone,

I would like to use a 10 MHz reference signal from an RF generator as an input for the RFSoC 4x2. Could you advise on the correct way to achieve this?

I attempted to connect the reference signal to the "SYNC IN" port and modified the PLL registers using TICS PRO, but it did not work. Additionally, I am unsure if this is the proper approach.

Any guidance would be greatly appreciated.

Best regards,
Diego Gallardo
