MIPI signal distance transmission device and method

Abstract

The invention aims at providing an MIPI signal distance transmission device and method. The transmission device comprises an access module, a parsing module, a receiving monitoring module, a clock processing module, a data processing module and a sending module; the access module is used for accessing a first level signal and a second level signal; the clock processing module is used for shaping aclock signal of an MIPI interface and extracting a frequency division signal; the receiving monitoring module is used for processing the first level signal accessed by the access module to obtain a synchronous signal; the parsing module is used for conducting parsing processing on the second level signal accessed by the access module according to the synchronous signal obtained by the receiving monitoring module to obtain video stream data; and the data processing module is used for conducting corresponding processing on the video stream data and then transmitting the processed video stream data to the sending module to allow the sending module to send the video stream data. Accordingly, the corresponding circuit area of a front end is decreased, the cost is reduced, and the transmissiondistance is increased.

Description

technical field [0001] The present application relates to the field of signal transmission, in particular to a MIPI signal distance transmission device and method. Background technique [0002] The interface of the current high-definition CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor) image sensor (higher than 720p) generally adopts MIPI (Mobile Industry Processor Interface, Mobile Industry Processor Interface Alliance) CSI-2 (Camera Serial Interface Version 2, camera Serial interface second edition) high-speed serial signal transmission standard or DVP (Digital Video Port, digital video interface) standard. Due to the large number of signal lines, the DVP interface standard is not suitable for long-distance signal transmission such as endoscopes. The serial MIPI interface standard has become the most suitable choice. However, since MIPI adopts the D-PHY physical layer standard, the amplitude of the signal in high-speed mode is only ...
