Working Principles

SN65LVDS22PWG4 utilizes LVDS technology to transmit high-speed data. It employs differential signaling, where data is transmitted as the voltage difference between two complementary signals (positive and negative). This method allows for noise rejection and enables long-distance data transmission with minimal signal degradation.

The device receives input data through the positive and negative input pins for each channel. It then processes and amplifies the signals before transmitting them differentially through the positive and negative output pins. The enable pins control the operation of each channel, allowing for selective data transmission.
