Abstract

Used to receive the digital signal after the sending position processing; the low -voltage differential signal input level, coupling through the signal line and the low -voltage differential signal output level,The low -voltage differential signal output level and the input level of the low -voltage differential signal input, coupled with the signal line, used to isolate the low -voltage differential signal output level co -mode voltage and the low -voltage differential signal input level co -mode voltage, And generate the co -modular voltage of the low -voltage differential signal input level.

Description

technical field [0001] The present invention relates to the technical field of circuits, and in particular, to a digital signal transmission processing device and method. Background technique [0002] LVDS (Low-Voltage Differential Signaling, Low-Voltage Differential Signaling) is a signal transmission mode voltage standard proposed by National Semiconductor (NS, now TI) in 1994. It can realize point-to-point or point-to-multipoint connection and has the advantages of low power consumption, low bit error rate, low crosstalk and low radiation. It has been widely used in serial high-speed data communication occasions, such as high-speed backplane , cable and board-to-board data transfer and clock distribution, and communication links within a single PCB. [0003] LVDS (Low Voltage Differential Signaling) is a physical layer data interface standard designed primarily for high-speed, low-power, and low-noise point-to-point communication over a 100Ω medium with controllable bala...
