BCM81118中文资料16nm 50GbE PAM-4 PHY (1:1) or (2:1)数据手册Broadcom规格书

描述 Description

The Broadcom BCM81118 is a single-chip low-power, low-latency PAM-4 PHY integrating retimer and equalizer functions supporting 50GbE applications.  In 50GbE mode, the BCM81118 retimes, and equalizes a 1×50G PAM-4 or 2×25G NRZ host side signal lanes into a 1×50G PAM-4 line-side signal to drive optical PAM-4 links inside next generation modules, including SFP56.  On-chip clock synthesis is performed by a low-cost 156.25 MHz reference clock via high-frequency, low jitter phase-locked loops (PLLs).  The BCM81118 is fabricated in advanced low-power 16 nm CMOS technology and is available in a RoHS-compliant package.
