AD9629 Differential Clock Input

Hi Guys,


Question regarding the AD9629 differential clock input. The datasheet (pg.20 - see attached) has the external clock terminated in a 50R load (figure 46) and then feeding into the Mini-circuits ADT1-1WT XFMR. This XFMR is specified in it's datasheet as 75R, so I'm wondering should the input be a 75R input from the external clock? Does this mean the differential outputs should also be 75R each, and is this suitable for feeding the CLK- and CLK+ pins of the AD9629? Your advice would be much appreciated.


Many Thanks,
