Working Principles

The DS90LV027ATMX operates based on the principles of differential signaling. It uses two complementary signals, one positive (TXP) and one negative (TXN), to represent digital data. These signals are transmitted differentially over a twisted pair of wires, which helps minimize noise and maintain signal integrity.

On the receiving end, the differential signals (RXP and RXN) are converted back into digital signals using a differential line receiver. The receiver compares the voltage difference between the two signals and determines the logic level of the received data.

The device also incorporates delay control to compensate for signal propagation delays, ensuring accurate data transmission and reception.
