Working Principles

The SN65LVDS22DRG4 is an LVDS driver IC that utilizes low-voltage differential signaling to transmit high-speed digital signals over long distances. It operates by converting single-ended input signals into differential output signals, which are then transmitted through a twisted-pair cable. The differential signaling helps in reducing electromagnetic interference and provides better noise immunity.

The IC receives the single-ended input signals on its IN1 and IN2 pins. These signals are then converted into differential signals using internal circuitry. The differential signals appear on the OUT1 and OUT2 pins, which can be connected to the receiving end of the communication system.
