Thanks again, I am sorry the link for the hardware is below.

The CPLD is powered from 5V, so you can connect this to the ADC ok.

I feel better connected the CPLD clock frequency to the ADC. I will have a go at this tomorrow and get some output traces. Before testing it actually on the hardware.

You need to create a slower speed clock in the CPLD and then connect that to the ADC. You would create the slower speed clock using a counter. The counter can be used to count the half-period of the clock you want, and then you toggle the clock output every time the counter completes (asserts carry-out). This gives you a nice square wave for the output clock.
