Working Principles

The SN65ELT22DR is designed to transmit and receive high-speed signals over long distances. It utilizes differential signaling, where the input signal is transmitted as the voltage difference between two pins (IN+ and IN-). This differential signal provides better noise immunity compared to single-ended signaling.

The IC incorporates a line driver that amplifies the input signal and a line receiver that converts the received differential signal back into a single-ended signal. The enable pin (EN) allows the user to control the operation of the IC by enabling or disabling the transmission/reception functionality.

Detailed Application Field Plans
