LVDS Output Interface Applications
LVDS specifies a small swing of 325mV typical, on a
nominal 1.2V common mode above ground. The
common mode voltage has tight limits to permit large
variations in the 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.
