I would like your kindly support to help me about the input clock HW configuration of HMC7044. If all references appear valid, PLL1 uses a reference priority table to select the best candidate.
a) Could I use only one external input reference on CLKIN0 (PIN39 and Pin 40)?
b) Should to add a phisical pull-down to the pins of CLKIN3, CLKIN2 and CLKIN1?
Thanks in advanced,
