To power-up the board, ensure that the VAR_VCCIOjumper is set to 3.3 V before
plugging the USB cable into the USB Type-B connector (J4).
Clock Circuitry
The development board includes a single-ended clock input on a 4-pin through-hole
socket. To replace the clock input with a different frequency oscillator, unplug the
current oscillator from the board and plug the desired oscillator into the 4-pin socket.
Figure 2–4 shows the MAX V CPLD development board clock input.
