Broadcom 7-nm CMOS 400G (4:4) PAM-4 PHY - BCM87840A0KEFBG

Product Description

Broadcom 7-nm CMOS 400G (4:4) PAM-4 PHY - BCM87840A0KEFBG

The Broadcom BCM87840 is the industry's highest- performance and lowest-power single-chip 400GbE PAM-4 PHY transceiver capable of driving four lanes of 106-Gb/s PAM-4 at 53 Gbaud, while supporting DR4, FR4, LR4, and QSFP112 optical links. 

The BCM87840 leverages Broadcom's market-leading 7-nm PAM-4 PHY transceiver technology platform already proven with BCM8740X PHY plus provides a path to accelerating 400G 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 12.8-Tb/s and higher-density switch ASICs inside pluggable optical modules and co-packaged optical solutions. 

The BCM87840 incorporates a highly differentiated feature set, including integrated voltage regulators, 400G FEC capability, and crossbar functionality to provide unmatched competitive advantage to the market. 

In 400GbE mode, the BCM87840 converts four lanes of 106 Gb/s (at 53-Gbaud PAM-4) from the system side into four lanes of 106 Gb/s (at 53-Gbaud PAM-4) to drive next- generation high-density optical PAM-4 links inside QSFP-DD and OSFP form-factor modules.
