what about the CLKOUT pin? The one next the CLKIN where you commonly connect the crystal?

But the fact is... Do you need the same frequency for your adc??? Or do you need a lower frequency? If so, the best is to use the CCP module and one timer with a CCP pin... (if you need a higher freq, better use an external source)

First check your datasheet about all this info...

Don't ADCs use clock just for shift register?
In that case you just need the clock while loading the data?
