Hello Amit

Thanks, and Happy New Year to you too!

I am fairly certain that no one has started porting the SKARAB ADC
firmware into a CASPER "yellow block" just yet. I would be happy to
support you on this. I don't see any limitations due to the new ADC
interface.

The Peralex-supplied JESD receiver core (included in the BSP) may need
to be adapted depending on your application (how the ADC is configured)
- the Peralex core is not currently a "generic" JESD core, rather it is
designed to receive JESD packets from the specific ADC configured with
specific mode/options (most notably output bandwidth). It may be easiest
to start porting this to yellow block directly first, and then
parameterise/extend the firmware/yellow block to support other ADC modes
(decimation rates, DDC bypass, etc) as needed.

There are a few restrictions that you need to be aware of in terms of
bandwidth/resolution trade-off if you change the ADC modes, particularly
when bypassing the ADC's built-in DDCs. If you can give me an idea of
how you specifically intend to use the ADC (mode/bandwidth/frequency
band), I can perhaps offer you some further advice.

Kind regards,
Clifford
