BCM85812: BROADCOM INTRODUCES NEW 800G PAM-4 TRANSCEIVER PHY
The monolithic fully integrated 800G PAM-4 PHY delivers best-in-class performance and efficiency for pluggable transceiver modules.
Broadcom Inc. has announced the availability of its 5nm 100G/lane optical PAM-4 DSP PHY with integrated transimpedance amplifier (TIA) and laser driver, the BCM85812, optimized for 800G DR8, 2x400G FR4 and 800G AOC module applications. Built on Broadcom’s proven 5nm 112G PAM-4 DSP platform, this fully integrated DSP PHY delivers superior performance and efficiency and drives the overall system power down to unprecedented levels for hyperscale data center and cloud providers.
BCM85812 Product Highlights
- Monolithic 5nm 800G PAM-4 PHY with integrated TIA and high-swing laser driver
- Delivers best-in-class module performance in BER and power consumption.
- Drives down 800G module power for SMF solutions to sub 11W and MMF solutions to sub 10W.
- Compliant with all applicable IEEE and OIF standards, capable of supporting MR links on the chip-to-module interface.
- Fully compliant with OIF 3.2T Co-Packaged Optical Module Specs
- Capable of supporting optical modules from 800G to 3.2T
Demo Showcases at OFC 2023
Broadcom will demonstrate the BCM85812 in an end-to-end link connecting two Tomahawk 5 (TH5) switches using Eoptolink’s 800G DR8 optical modules. Attendees will see a live traffic stream of 800GbE data running between two TH5 switches. Broadcom will showcase various 800G DR8, 2x400G FR4, 2x400G DR4, 800G SR8, and 800G AOC solutions from third-party transceiver vendors that interoperate with each other, all using Broadcom’s DSP solutions.
Additionally, Broadcom in collaboration with Semtech and Keysight will demonstrate a 200G per lane (200G/lane) optical transmission link leveraging Broadcom’s latest SerDes, DSP and laser technology. These demonstrations will be in Broadcom Booth 6425 at the Optical Fiber Communication (OFC) 2023 exhibition in San Diego, California from March 7th to 9th.
