AD9176 Clocking Recommendations


With the AD9176-FMC-EBZ evaluation board, we are creating a wide-band transmitter, using specifically JESD modes 12, 20, or 21. 

As the clocking and the jitter associated with it greatly dictates the overall system performance, would the on-board clocking capabilities be suitable for these modes of operation at their limits or would an external clock be recommended?

And if an external clock is recommended, is there a specific one you would recommend with better jitter performance, frequency flexibility, a relatively small form factor, and meeting or exceeding the 12dBm power requirement of the AD9176 for direct clocking?
