CLK 1 is the clock input and must be a half rate clock for 1:4 demultiplexing or
full rate clock for 1:2 demultiplexing. This input is AC coupled.
The phase adjust knob aligns the clock edge to the middle of the opening in
the input data eye for error free output from the demultiplexer.
The Data In and Data In/ are differential inputs for the data. These
connectors are 1.85 mm female connectors. If the data input is used single
ended the input should be connected through a DC block and the unused
input should be terminated with a 50 Ω 1.85 mm terminator.
The demuxed data outputs are routed thru the Demux Data Out1 through
Demux Data Out4 connectors. These are 2.92 mm female connectors. They
are single ended AC coupled outputs.
