Broadcom 7 nm 400GbE PAM-4 PHY (8:4) Direct Drive- BCM87402A2KREBG
The Broadcom BCM8740x series of devices are the industry’s highest performance and lowest power single-chip 400GbE PAM-4 PHY transceiver platform capable of driving four lanes of 112-Gb/s PAM-4 at 56 Gbaud, while supporting DR4/FR4/LR4 optical links. In 400GbE mode, the BCM87402 converts eight lanes of 53 Gb/s (at 26-Gbaud PAM-4) from the system side into four lanes of 106 Gb/s (at 53-Gbaud PAM-4) with direct-drive capability for EMLs and Silicon Photonics. The BCM87402 leverages Broadcom's market-leading PAM-4 PHY technology platform and represents the industry's first 400G PAM-4 PHY transceiver with a monolithically integrated 56-GBaud PAM-4 laser driver in 7-nm CMOS. Broadcom's advanced DSP technology and equalization techniques compensate for optical impairments while maintaining the world's lowest power, enabling the deployment inside pluggable optical modules and co-packaged optical solutions.
