Abstract
This paper presents an 86. 71875GHz R transceiver IC featuring a fully integrated clock and data recovery (CDR)-assisted carrier synchronization loop for waveguide links. The IC fabricated in 28nm CMOS demonstrates 57. 8125Gb/s PAM-4 data transmission over a 1. 5m waveguide channel. The proposed carrier synchronization can be achieved only by using a base-band CDR without using power-and-area-hungry RF circuits. The test chip achieves the best figure of merit (FoM) of 3. 5pJ/b/m in terms of throughput-distance, and energy efficiency compared to the prior art.
