Remove X2, add J2001.  Feed J2001 a CMOS-level clock.

The clock you send in will be your ADC sampling clock.  Your DAC sampling will
be 2X the frequency you send in.  Your clock should be less than or equal to 64

The FPGA will operate at your clock rate unless you make changes to the FPGA
design to use the internal PLLs.
