Working Principles

SN65LVDS93AZQLR operates based on the LVDS signaling standard. It uses a differential voltage scheme, where data is transmitted as the voltage difference between two lines (positive and negative). This differential signaling allows for high-speed data transfer while minimizing electromagnetic interference.

The transceiver receives differential input signals and converts them into single-ended signals for internal processing. It then converts these processed signals back into differential outputs for transmission. The device also incorporates features like pre-emphasis and equalization to compensate for signal degradation over long distances.
