Problem with Clocking System in RFSoC 4x2

Support

Hi!,

We are having terrible troubles using the RFSoC 4x2 aside of PYNQ.

Our purpose now is to read a internally generated sinewave with the RFDAC, however, we can’t activate the clock for working with the DAC. In our understanding we need to setup the clock according to the specification of our IP RFDC aside of setting this block up, however we can’t find any example with headers and the main file that sets at least the example of RealDigital to get an idea how to do it.

We appreciate any help on this. And hopefully not a “read the manual”, because actually that answer is very demotivating for all the hours spent on this task (no homework, just learning by ourselves).

Best regards.

Hi,
In the block design of the overlay in your RF Soc 4x2, what is the clock the RF Data Converter block is receiving?

Have you tried testing the DAC via this loopback test in this jupyter notebook?

Hi @cguc,

Have you checked this design? GitHub - Xilinx/RFSoC-MTS: A PYNQ overlay demonstrating AMD RFSoC Multi-Tile Synchronization (MTS).
