Falcon-RX switch alternative

Is it possible to replace the Falcon-RX with something like

https://store.timebeat.app/products/open-timecard ?

it has a 10G network interface with ptp. Can I just put it in a server running srsRAN and connect split 7.2 RU to that 10G network interface? Or is it better to use µFalcon-RX?

BTW do I need Rb clock or just OCXO is ok? GNSS signal where I live is good.

No, the PHY on the Timecard is just a Intel i226 I think, it's a 1G Ethernet PHY only. The SFP cage I guess is just for convenience.
However, Timebeat also has slightly modified Intel E810s that allow external PPS input from e.g. the Timecard or another PPS source. Those NICs work well as OFH NICs.

Thank you for information. With this NIC

it should be ok right?

If you use a normal E810 or this modified version you need to tame the PHC on the card with an external PPS signal. The adapter just provides you a way to connect it over SMA.
The other alternative is to get the E810 with GPS receiver mounted on the card https://cdrdv2-public.intel.com/641626/Intel%20Ethernet%20Network%20Adapter%20E810-XXVDA4T%20Product%20Brief.pdf

Thank you very much. I got the idea.
