Hi

We are trying to route a signal from FDSP channel 2 to PDM output, but the only thing we see on the PDM output is noise. Changing to routing to a different FDSP or SDSP channel does not seem to have any impact.

PDM output is routed to MPX5, CLK, and MPX6 Data.

It seems as if the PDM routing is not functioning

thanks

ADI North America will be on winter shutdown starting December 24, 2024; perhaps another community member can assist you until our return on January 2, 2025.

Moti,

Can you share your SigmaStudio project? It should be noted the PDM outputs need to be enabled in the PWR tab as well.

Thanks,
PG

thanks, after some tweaking it started working as expected
