Broadcom 7-nm CMOS 800GbE (8:8) PAM-4 PHY - BCM87800
The Broadcom BCM87800 is the industry’s highest-performance and lowest-power single-chip 800GbE PAM-4 PHY transceiver capable of driving eight lanes of 106-Gb/s PAM-4 at 53 Gbaud, while supporting DR8 and 2xFR4 optical links. The BCM87800 leverages Broadcom’s market-leading 7-nm PAM-4 PHY transceiver technology platform already proven with the BCM8740X PHY, and it provides a path to accelerating 800G QSFP-DD/OSFP optical module availability. Broadcom’s advanced DSP technology and equalization techniques compensate for optical impairments while maintaining the world’s lowest power to enable the deployment of 25.6 Tb/s and higher- density switch ASICs inside pluggable optical modules and co-packaged optical solutions.
