÷1/÷2 DIFFERENTIAL-TO-LVDS CLOCK GENERATOR

A general LVDS interface is shown in Figure 4. In a 100

Ω

differential transmission line environment, LVDS drivers require

a matched load termination of 100

Ω across near the receiver

input. For a multiple LVDS outputs buffer, if only partial outputs

are used, it is recommended to terminate the unused outputs.
