LVDS (low-voltage differential signaling)

LVDS (low-voltage differential signaling) is a high-speed, long-distance digital interface for serial communication (sending one bit at time) over two copper wires (differential) that are placed at 180 degrees from each other. This configuration reduces noise emission by making the noise more findable and filterable. LVDS is often used in SerDes configurations.

LVDS outputs are capable of keeping up with the high data rates and keeping noise emission low, thus protecting the performance of the analog front end. Additionally, some manufacturers have reduced the number of wires necessary to transmit the signals from one point to another by serializing the output bits onto an LVDS pair, which further improves accuracy by avoiding skew-related errors that can occur when transmitting data in parallel.
