描述 Description

The Broadcom BCM81188 is a single-chip, low-power, low-latency PAM-4 PHY that integrates retimer and qualizer functions to support 400GbE applications.  In 400GbE mode, the BCM81188 converts 16 × 25G NRZ or 8 × 50G PAM-4 host side into 8 × 50G PAM-4 line side to drive optical PAM-4 links inside next generation modules, including CFP8. The BCM81188 is compliant to 400G data in accordance with IEEE 802.3bs standards.  The device also supports Broadcom's proprietary high gain Super-FEC (S-FEC) for extended reach applications. The BCM81188 supports both 400G and Quad 100G modes. 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 BCM81188 is fabricated in advanced low-power 16 nm CMOS technology and is available in a RoHS-compliant package.
