Optical transmitter and receiver chip structure for synchronously networking by using reverse clock

Abstract

The invention provides an optical transmitter and receiver chip structure for synchronously networking by using a reverse clock. Clock synchronization is carried out among a plurality of chips, therefore, convergence of data among the chips can be realized, and digital sampling of digital convergence is ensured, so that a transmitted signal is enabled to be complete. The optical transmitter and receiver chip structure comprises a digital to analog converter, an analog to digital converter, a digital logic module, a staticizer and a clock signal module, and is characterized by also comprising a clock restoring circuit, a local/remote clock selective switch and a serializer, wherein the output end of the digital to analog converter is externally connected with an analog video output, an analog video input is connected with the input end of the analog to digital converter, the output end of the analog to digital converter is connected with the input end of the digital logic module, the output end of the digital logic module is connected with the input end of the serializer, and the output end of the serializer is externally connected with an optical module through a data line.
