10GBASE-T PHY enables single row top-of-rack design
Broadcom Corporation announced the availability of what is said to be the industry's smallest quad 10GBASE-T physical layer transceiver (PHY). The BCM84848 second-generation 40nm 10GBASE-T PHY delivers 50 percent lower power in the industry's smallest footprint, according to the company, to enable next-generation 10GBASE-T Top-of-Rack switch platforms. Designed as a companion device to the StrataXGS Trident Switch Series, this PHY allows OEMs to implement top-of-rack switches with 48 ports of 10GBASE-T and four 40 Gigabit Ethernet (GbE) QSFP uplinks while maintaining minimal depth of the platform, thus avoiding the dual row layout required with larger PHY packages. Offering a small footprint via a 23-mm x 23-mm package, the BCM84848 PHY allows sufficient space for QSFP uplinks and 10GBASE-T RJ45 connectors. Forward compatibility to next-generation 28nm process ensures scalability and preserves customer investments, eliminating the need to redesign the board when moving to the next node.
