Bangalore: Broadcom Corporation, a global innovator in semiconductor solutions for wired and wireless communications, announced the availability of 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 to enable next-generation 10GBASE-T Top-of-Rack switch platforms.

As demands for greater processing power and performance impose on rack space, OEM and ODM system designers must reduce footprint and power consumption. Designed as a companion device to Broadcom’s StrataXGS Trident Switch Series, the highly integrated BCM84848 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 the industry’s smallest footprint with a 23 x 23mm package, the BCM84848 PHY allows sufficient space for QSFP uplinks and 10GBASE-T RJ45 connectors, providing OEMs with a distinct competitive advantage. 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.

The BCM84848 PHY features Energy Efficient Ethernet (EEE) technology for multiple speeds including 10GBASE-T, 1000BASE-T and 100BASE-TX, expanding energy savings throughout the network by automatically reducing power consumption during periods of no activity.

The key features include robust operation over 100 meter Category 6a cables with industry standard 4-pair magnetic, lower total cost of ownership with auto-negotiation that reduces system administration costs, IEEE 1588v2 with one-step timestamp insertion provides high accuracy timing, IEEE 802.1ae MACsec provides link layer security, supports multiple speeds including 10GBASE-T, 1000BASE-T and 100BASE-TX with EEE supported on all three speeds.
