LVDS
Depending on whether the device is transmitting an LVDS
signal or receiving an LVDS signal, there are two different
circuits used for LVDS termination. A sample circuit illustrat-
ing a valid termination technique for transmitting LVDS sig-
nals appears in
valid termination for receiving LVDS signals appears in
