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.
