4.2.5 Configuring the Output Clock Termination

The LMK6BEVM comes pre-populated with an AC-coupled termination designed for LP-HCSL, LVDS, AC-LVPECL, and custom swing output formats. For the LVDS, AC-LVPECL, and custom swing output types, terminate the output with a 100Ω differential termination. If the output is AC-coupled, terminate the P and N channels with 50Ω tied to a bias voltage to set the desired common mode voltage.

For LP-HCSL, the output can interface with a high-impedance load to provide the full signal swing. Unlike conventional HCSL drivers, no external termination resistors are required.
