Table 6 of UG-992 specifies that only 4 ADCs can be used as inputs at any one time. What isn't clear is context. Is this a limit on the main RX path framer, or on the system?
What we want to do is to use both Main RX paths, and the observation receiver simultaneously.
If table 6 indicates 4 ADCs total can be used, then both main RX and one Obs RX cannot be used simultaneously.
If table 6 indicates 4 ADCs total can be used by the main RX framer, then we could assign 2 lanes to the main RX paths, and one to the Obs RX path.
I believe that table 6 refers only to the main RX framer. Can someone confirm this?
