8.4.1 LVDS Output Termination

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

The LMK1D210x can be connected to LVDS receiver inputs with DC and AC coupling as shown in Figure 8-1 and Figure 8-2, respectively.
