24 to 34-Gb/s ×4 multi-rate VCSEL-based optical transceiver with referenceless CDR

摘要

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 x4 interconnect with retime function.
