24 to 34-Gb/s ×4 Multi-Rate VCSEL-Based Optical Transceiver with Referenceless CDR

Abstract

A high-density multi-rate VCSEL transceiver with CDRs was developed. We succeed in suppressing the jitter of optical link by developing CDR for the receiver, and realized a 24 to 34-Gb/s ×4 interconnect with retime function.
