CML DC ELECTRICAL CHARACTERISTICS(1)
NOTE:
1. Actual voltage levels and differential swing will depend on customer termination scheme. Typically, a 400mV swing is available in the 100 environment
and a 200mV swing in the 50 environment. Refer to the “CML Output” diagram for more details.

conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for extended periods
may affect device reliability.
