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?
The clock distribution we had been investigated for high performance like below.
ADF4372 + Balun(diff to single ended) + BPF( filtering out ADF4372 sub-harmonics & harmonics) + HMC3653(or equivalent gain block) + Balun(single to diff)
