What does this do?
Where would it be wired into a CD player?

We have not been given a look at the bottom of correctly, there's no RAM. the pcb. Maybe there are components on that side too.
Edit: if I interpret the function block diagram of the XC9572XL corrcetly, it has no RAM.
I would take it for what the title says: SPDIF isolator (I presume galvanic isolation) and low jitter clock, but no jitter-killer.

With a more careful reading of the function description, it appears that the board simply re-generates a cleaner S/PDIF waveform. To do this with only digital means they would need to time-slice the input S/PDIF signal, hence, I presume, the TCXO. In any case, I think it not justified for anyone to reflexively declare that the FPGA cannot play a role in jitter reduction. They can and they do form key parts of a DPLL, for example, in commercial DAC boxes. Even of the FPGA here is not being utililzed to create a DPLL.
