We are currently using these two of these chips on our IF boards (attached to the MKID ADC and DAC boards) to both generate clocks for the ADC/DAC /ROACH and to generate a RF signal for up and down conversion. We are pretty happy with the performance - in the testing we've done so far we haven't seen any noticeable degradation using these instead of the SRS clock generator.
