Figure 1 shows a typical termination for LVDS driver in charac-

teristic impedance of 100

Ω differential (50Ω single) transmis-

sion line environment. For buffer with multiple LDVS driver, it is

recommended to terminate the unused output.

To prevent oscillation and to reduce noise, it is recommended to

have pull up and pull down connected to true and complement of

the unused input as shown in
