[PS2] Anyone know what chip the Modbo 5.0 is based on?

Was wondering, as I'm building an IDE to EXI adapter for my gamecube, which requires an old PS2 modchip (based on a xilinx chip) for some reason.
The only modchip I can seem to find for the PS2 is the Modbo 5.0. Does anybody know if it uses a xilinx chip?

Googled around to no avail, figured this would be the best place to check.


Thanks in advance!
