A Multi-wire Dynamic Encoding Chiplet High-speed Transmission Interface - CNRZ-5

A multi-wire high-speed modulation technique termed “Correlated Non-Return-to-Zero with five sub-channels (CNRZ-5)” is introduced, along with two code variants, namely, the CNRZ-5 Base code, and the CNRZ-5 EqualSignal code. Three test channels of the combinations of high/low reflection/losses are created. The data transmission performances of six scenarios, i.e., the combinations of two code variants and three test channels, as well as NRZ in one scenario are compared. The simulation results show that CNRZ-5 is capable of offering the flexibility of using programmable encoding schemes to adapt to channel conditions, while delivering remarkably superior performance to NRZ.
