CML Termination
All inputs accept the output from any other member of
this family. All outputs are source terminated 100Ω CML
differential drivers as shown in Figures 3 and 4.
SY55854U expects the inputs to be terminated, and that
good high speed design practices be adhered to.
SY55854U inputs are designed to accept a termination
resistor between the true and complement inputs of a
differential pair. 0402 form factor chip resistors will fit
with some trace fanout.
