In the field of radar application, with the development of technology and the emergence and popularization of new system radars, such as DBF System Radar and phased array radar, the signal bandwidth and the number of signal channels to be processed have increased significantly, facing the problem of large amount of data transmission. Therefore, the new technology used to solve the I / O interface problem has become an inevitable trend. LVDS, a high-speed and low-power interface standard, makes it possible to solve this transmission bottleneck problem. Therefore, LVDS technology is widely used in high-speed radar and high-speed receiving system; LVDS technology is used to realize point-to-point single board interconnection. The system structure has very good scalability, realizes the high integration of line card and each subsystem, and can fully meet the requirements of data acquisition and transmission.
In civil use, this technology can support high-speed data transmission, and is most suitable for communication structure application schemes such as base stations, switches, plus / minus multiplexers, consumer product application schemes such as set-top boxes and home / enterprise video links, as well as medical ultrasonic imaging equipment and digital photocopiers, so as to ensure greater flexibility in system partition operation. System design engineers can use LVDS technology to set analog and digital signal processing sections on different circuit boards, and then use cables or backplanes to transmit the digital data output by a / D converters, so as to ensure greater flexibility in structural design. At present, all kinds of high-speed AD converters basically choose LVDS signal as the output format of sampling data, and most of its output forms are parallel output. At the same time, special chips supporting IWDS and other level exchange and LVDS speed reduction are also emerging in endlessly, mainly represented by several foreign companies such as maxm, Ni and Ti.
