The PHY, which is 28nm, utilises eight system-side and 16 line-side differential, high performance I/Os with transmit and receive equalisation. This provides longer channel lengths and improved jitter performance. The BCM82764 is fully-compliant to many 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, Executive Vice President and General Manager, Infrastructure & Networking Group, Broadcom. “Our 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.”
