At present, the popular LVDS technical specifications have two standards: one is TIA / EIA (Telecommunications Industry Alliance / Electronic Industry Alliance) ANSI / TIA / EIA-644 standard, and the other is IEEE 1596.3 standard. In November 1995, the ANSI / TIA / EIA-644 standard was introduced mainly by National Semiconductor Corporation. In March 1996, IEEE published the IEEE 1596.3 standard. These two standards focus on the specifications of the electrical characteristics, interconnection and line termination of the LVDS interface, but are not clear about the production process, transmission medium and power supply voltage. LVDS can be implemented with CMOS, GaAs or other technologies, and its power supply voltage can be from + 5V to + 3.3V or even lower; its transmission medium can be a PCB connection or a special cable. The maximum data transmission rate recommended by the standard is 655Mbps, and in theory, on a lossless transmission line, the maximum transmission rate of LVDS can reach 1.923Gbps.
