ispClock5600A: What are the necessary configurations for using the ispClock5600A with single ended input clocks?
Single ended input clocks use the configuration described on pg21 of the ispClock5600A datasheet
A summary of the configuration
REFA+ is to be connected to the input clock
REFA- is to be connected to GND.
REFVTT is also to be connected to GND, with the input termination resistors set to open in the PAC-Designer software
If external, single-ended feedback is used, FBK+ is to be connected to the feedback clock, and FBK- is to be connected to GND
