RFSoC Converter tile NCO Word

Hi,

A question that came out of design review was how is the NCO word synchronised up to the higher sample frequency for the NCO?

I appreciate that the NCO word, provided on the real time port is related to the AXI lite clock, but at some point this must be synchronised internally to the sample rate clock.

Kind regards,

Paul

Hi @paulnorris 

Good question. I would have to ask this to the engineering team that owns this IP. 

I expect that an update should be synched to the digital clock for the data path. I will check this.
