Note 1.
Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not
implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratlng conditions
for extended periods may affect device reliability.

Load CML Output
All CML inputs accept a CML output from any other
member of this family.
All CML outputs are source
terminated 50 differential drivers as shown in Figure 4.
SY55856U expects its inputs to be externally terminated.
SY55856U inputs are designed to accept a termination
resistor between the true and complement inputs of a CML
differential input pair, as shown in Figure 4.
