Design of Highly Reliable Digital Signal Transmission System Based on Serial Communication Protocol

In order to improve the signal transmission reliability of high-speed serial digital communication, this paper designs a digital signal transmission system based on the transceiver chip TLK2711. The scheme has the advantages of high transmission rate, simple interface and strong anti-interference ability. It can be widely used in various areas of digital communications. The TLK2711 transmits the 16-bit data and control code TKLSB and TKMSB through the 8B/10B encoder to generate 10-bit valid data to the 2:1 multiplexer, and then sends it to the serializer for completion. The data is converted from parallel to serial, correctly transmitted to the receiving end, and correctly parsed by the receiving device, and a reasonable transmission protocol needs to be defined. The article gives the detailed design scheme, usage and the working mode of each module of the system, examples and references are given for similar system design. In practical application, it can be improved according to the characteristics of the use plan and the actual needs of the design.
