摘要
本文提出了一种低功耗、基于dsp的单片800GbE PAM-4 PHY收发器，采用7nm工艺，可驱动8通道，最高速率为112gb /s。它通过单片集成激光驱动器支持电气和光学链路，为EML和硅光子学提供直接驱动PAM-4输出能力。收发器在奈奎斯特支持42 dB IL通道，预fec误码率<3E-8。低摆幅驱动模式下的每车道模拟功率效率为2.59pJ/b，直接驱动模式下为4.58 pJ/b。
An 800GbE PAM-4 PHY Transceiver for 42 dB Copper and Direct-Drive Optical Applications in 7 nm
This work presents a low power DSP-based single-chip 800GbE PAM-4 PHY transceiver in 7 nm process capable of driving eight lanes of up to 112-Gb/s. It supports both electrical and optical links with monolithic integrated laser driver enabling direct-drive PAM-4 output capability for EML and silicon photonics. The transceiver supports 42 dB IL channel at Nyquist with pre-FEC BER<3E-8. The per-lane analog power efficiency is 2.59pJ/b for low-swing drive mode and 4.58 pJ/b for direct-drive mode.
