8.4.1 LVDS Output Termination

TI recommends unused outputs to be terminated differentially with a 100Ω resistor for optimum performance, although unterminated outputs are also okay but results in slight degradation in performance (Output AC common-mode VOS ) in the outputs being used.

The LMK1D120x can be connected to LVDS receiver inputs with DC- and AC-coupling as shown in Figure 8-1 and Figure 8-2 (respectively).
