Is there a FIFO on the Rx path of ADRV9009? Similar to that of the Tx path?
From UG-1295: "The FIFO depth can be checked in Register 0x15CE for Deframer 0 and in
Register 0x161E for Deframer 1." Is there something similar for the Framers A and B?
I have observed that the Rx latency can increase by 32 samples from reboot to reboot (randomly). Then I have changed .framerA.lmfcOffset from 31 to 15, and it seems it has solved the issue.
So we have to do multiple power reboots, multiple tests, to gain some confidence that our value is good? But may be not optimal... On what depends this value? With another board (sample) of the same model, should the result be the same?

Yes, after multiple reboots the latency should be constant .

It's better to verify on 5 or more samples and fix the LMFC offset value.
