Low-voltage differential signaling, or LVDS,'s an electrical signaling system that can run at very high speeds over inexpensive twisted-pair copper cables. It was introduced in 1994, and has since become very popular in computers, where it forms part of very high-speed networks and computer buses. Differential vs single-ended signaling LVDS's a differential signaling system, which means that it transmits two different voltages which are compared at the receiver. LVDS uses this difference in vo… (More on Lvds)
