Product Description
Broadcom 7 nm 100GbE PAM-4 PHY (4:1/2:1) Direct Drive - BCM87102
The Broadcom BCM8710x series of devices are the industry’s first and highest performance and lowest power single-chip 100GbE PAM-4 PHY transceiver platform capable of driving 112-Gb/s PAM-4 at 56 Gbaud, while supporting DR/FR/LR optical links. In 100GbE mode, the BCM87102 converts either four lanes of 25.7815 Gb/s NRZ or two lanes of 53.125 Gb/s (at 26.5625-Gbaud PAM-4) from the client/system side into one lane of 106.25 Gb/s (at 53.125-Gbaud PAM-4) on the line/optics side with Direct Drive capability for EML and Silicon Photonics. Leveraging Broadcom's market-leading PAM-4 PHY technology platform, the BCM87102 represents the industry's first 100G PAM-4 PHY transceiver available in 7-nm CMOS and includes the required FEC generation and termination capability for DR4 to DR1 break-out mode and longer distance optical links and a monolithically integrated 56-GBaud PAM-4 laser driver for EML and Silicon Photonics. The BCM87102 also enables re-use of BCM8740x series advanced API-based firmware for significant module development and deployment time improvements.
