OUTPUT INTERFACE APPLICATIONS

LVDS specifies a small swing of 350mV typical, on a

nominal 1.25V common mode above ground. The common

mode voltage has tight limits to permit large variations in

ground between an LVDS driver and receiver. Also, change

in common mode voltage, as a function of data input, is

kept to a minimum, to keep EMI low.
