# AX2771 sample clock on PMOD J13. The 100/125 MHz GPS clocks generated by the
# two Efinity PLLs are frequency-related to this input; the Rocket fabric clock
# comes from the independent on-board 100 MHz oscillator.

# The FTDI adapter is normally run at 1 MHz. Constraining the hard-TAP fabric
# interface to 10 MHz leaves margin if the debug adapter speed is increased.
