What is the correct way of driving the ADF5355 with a single ended clock?  There seems to be some ambiguities between the datasheet and the Users guide.

The datasheet says "connect reference clock to REFINA". There is no more details. What do I do with REFINB?


The Users guide says, in reference to the eval board:

To use a single-ended REFINx, connect a low noise 122.88 MHz reference source to SMA REFINB, and connect a 50 Ω terminator to SMA REFINA. Remove Resistor R27 (100 Ω).


Also I am using a 100MHz clock not a 122.88MHz, is that okay?
