I'm designing an ADC module using HMC7044, one of the clocking modes needs HMC7044 to work as a fanout buffer like HMC7043.
So I studied the data sheet of HMC7044. The fanout mode is metioned several times inside, but no further details are present. Is the mode supported in HMC7044? If so, how is the mode configured in the registers? I found some registers possibly related to the mode, which are: 0x0003[4:3], 0x0005, 0x0064[1:0]. Is properly setting these registers adequate for fanout mode to work? (Of course I still need to set the output channels.) Can I turn off PLL1 and PLL2 during fanout mode?
