Working Principles

The LTC2862AMPS8-1#TRPBF operates based on the principles of differential signaling. It uses two complementary signals, A and B, to transmit data over a twisted pair cable. The driver section amplifies the differential signals, while the receiver section detects and converts them back into digital data.

During transmission, the driver outputs either a high or low voltage level on the A and B pins, creating a voltage difference between them. The receiver then compares the voltage levels on the twisted pair cable to determine the transmitted data.
