Working Principles

SN75LVDS391D works based on the LVDS technology, which uses a differential signaling scheme. In this scheme, data is transmitted as a pair of complementary signals, with one signal being the inverse of the other. This differential signaling helps in reducing common-mode noise and improving noise immunity.

The transmitter receives digital data inputs and converts them into LVDS signals. These LVDS signals are then transmitted differentially through the corresponding output channels. At the receiving end, an LVDS receiver decodes the differential signals back into digital data.
