Broadcom Introduces Industry's First 40GbE Quad Port Gearbox PHY

IRVINE, CA -- Broadcom Corporation announces the industry's first quad port 40GbE gearbox PHY supporting 20 Gbps input/output (IO) designs. Optimized as a companion device to Broadcom's new StrataXGS® Tomahawk™ Switch Series, the BCM82764 high density gearbox physical layer transceiver (PHY) converts 20 Gbps signals to multiple lanes running at 10 Gbps. Using Broadcom's companion PHY, customers have the option to provide legacy 40GbE ports while taking advantage of the full bandwidth of the switch. For more news, visit Broadcom's Newsroom.

Engineered for high density switch environments, Broadcom's innovative 28 nanometer (nm) PHY utilizes eight system-side and 16 line-side differential, high performance input/outputs (IOs) with transmit and receive equalization, enabling both longer channel lengths and jitter performance optimization. The new PHY provides a fully standard-compliant interface to some of the most widely used 40G Ethernet PMDs including CR4, LR4 and SR4 links.

"The introduction of Broadcom's StrataXGS Tomahawk Switch Series and companion quad-port gearbox PHY once again demonstrates our ability to bring a cohesive solution to market," said Rajiv Ramaswami, Broadcom Executive Vice President and General Manager, Infrastructure & Networking Group. "Our new 40G Ethernet gearbox facilitates extremely large switch radixes while using minimal power and real estate, providing a very attractive option for system designers developing next generation cloud scale networking equipment."
