7.1 Overview

Figure 7-1 shows how LVDS drivers and receivers are intended to be used primarily in a simple point-to-point configuration. This configuration provides a clean signaling environment for the fast edge rates of the drivers. The receiver is connected to the source through a impedance controlled 100Ω differential PCB traces. Use a termination resistor of 100Ω and place it as close to the receiver input pins as possible. The termination resistor converts the driver output (current mode) into a voltage that is detected by the receiver.
