LVDS Description and Family Characteristics
Low Voltage Differential Signaling (LVDS) defines a reduced swing, differential I/O technology for high-speed interface (Figure 1 and Figure 2). Many LVDS devices are defined by the ANSI/TIA/EIA-644 standard also known as RS-644. RS-644 compliant devices provide specific I/O characteristics designed to provide a low noise, low power, low EMI, high-speed interface. All Fairchild LVDS devices meet or exceed the ANSI/TIA/EIA-644 standard. LVDS devices are typically used for point-to-point and limited multi-drop cable driving configurations.
