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

AN1035, AN977, AN971, AN916, AN805, AN903.
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
stub(s), and other impedance discontinuities as well as
ground shifting, noise margin limits, and total termination
loading must be taken into account.
The DS90LV018A differential line receiver is capable of de-
tecting signals as low as 100 mV, over a
range centered around +1.2V. This is related to the driver
