A 224Gb/s per wire single-ended PAM-4 transceiver front-end achieves high-density communication, doubling pin efficiency compared to standard differential signaling systems.
Up to 29dB equalization compensates severe channel insertion loss across long-reach wireline channels, ensuring reliable data recovery at 224Gb/s per lane.
Architectural analysis of single-ended channels demonstrates operation beyond 30dB insertion loss, suggesting viable integration into 800GbE and 1.6TbE systems.
