Working Principles

The MAX9120EXK-T is designed to transmit and receive high-speed signals over long distances. It utilizes differential signaling, where data is transmitted as the voltage difference between two complementary signals. This approach minimizes noise susceptibility and enhances signal integrity.

The driver section of the IC amplifies the input differential signal and drives it onto the transmission line. On the receiving end, the receiver section detects the differential voltage and converts it back into a digital signal. The receiver also incorporates a threshold voltage reference (VREF) for accurate detection of the received signal.
