A two-phase return-to-zero (RZ) asynchronous transceiver circuit for pipe-lined SoC interconnects

Abstract

A new delay-insensitive two-phase asynchronous handshaking protocol has been developed. The new protocol utilizes return to zero data format which simplifies communication circuits design significantly. Robust transceiver circuitry that implement this protocol have been developed and simulated using a 0.13mum, 1.2V technology to verify their performance.
