LVDS Description and Family Characteristics
Low Voltage Differential Signaling (LVDS) defines areduced swing, differential I/O technology for high-speedinterface (Figure 1 and Figure 2). Many LVDS devices aredefined by the ANSI/TIA/EIA-4 standard also known asRS-4. RS-4 compliant devices provide specific I/Ocharacteristics designed to provide a low noise, low power,low EMI, high-speed interface. All Fairchild LVDS devicesmeet or exceed the ANSI/TIA/EIA-4 standard.
LVDS devices are typically used for point-to-point and lim-ited multi-drop cable driving configurations. Many FairchildLVDS devices offer features to increase performance suchas common mode (Figure 3) for increased application flexi-bility and failsafe to eliminate false or unexpected states.Many LVDS devices are pin replacements for existing inter-face technologies such as RS-422, PECL, and LVPECL.This compatibility makes upgrades to higher performancepossible with minimum redesign.
