Design of scrambling circuit of 100Mb/s Automotive Ethernet Physical Coding Sublayer
In order to avoid the spectral spurious caused by the high-speed data transmission process,based on the protocol IEEE 802.3bw,this paper proposes a side-stream processing system that conforms to the coding sublayer(PCS)transmission under the 100BASE-T1 Ethernet physical layer(PHY).Design and implementation of scram-bling and descrambling circuit.This paper expounds the principle details of side stream scrambling and descrambling,and designs a side stream scrambling and side stream descrambling circuit based on the classical state machine struc-ture,combined with the internal control signals of the protocol and the requirements of data flow.Through the realiza-tion and simulation of the design,the simulation results meet the requirements of the protocol,and the scrambling and descrambling circuit is compatible with the control signal of the PCS system,and can be applied to the design of the 100Mb/s automotive Ethernet interface circuit.
