General application guidelines and hints for LVDS drivers
and receivers may be found in the following application

AN-977, AN-971, AN-916, AN-805, AN-903.
LVDS drivers and receivers are intended to be primarily used
in an uncomplicated point-to-point configuration as is shown
in Figure 3. This configuration provides a clean signaling
environment for the fast edge rates of the drivers. The re-
ceiver is connected to the driver through a balanced media

which may be a standard twisted pair cable, a parallel pair
cable, or simply PCB traces. Typically the characteristic
impedance of the media is in the range of 100Ω. A termina-
tion resistor of 100Ω should be selected to match the media,
and is located as close to the receiver input pins as possible.
The termination resistor converts the driver output (current
mode) into a voltage that is detected by the receiver. Other
configurations are possible such as a multi-receiver configu-
ration, but the effects of a mid-stream connector(s), cable
