Broadcom Introduces First .13-Micron Gigabit Ethernet Octal Transceiver

10/14/2004 - Broadcom Corporation (Nasdaq: BRCM), a leading provider of highly integrated semiconductor solutions enabling broadband communications, announced the industry's first 0.13-micron octal transceiver optimized for high-port density Gigabit Ethernet (GbE) switches, routers and server blades. Since low power is a key ingredient for implementing high-density Gigabit Ethernet switches, Broadcom's third generation 0.13-micron Gigabit Ethernet physical layer (PHY) device is capable of operating with less than 600-milliwatts per port, resulting in a 25% power reduction over existing Broadcom Gigabit Ethernet PHYs.

Power dissipation is a critical design factor for higher-density transceiver solutions. The dramatic power reduction achieved by the new Broadcom® BCM5478 enables the use of standard packaging, and makes it an ideal companion chip in systems that contain advanced switch ASICs with RGMII (reduced Gigabit media independent interfaces) or SGMII (serial Gigabit media independent interfaces) such as Broadcom's StrataXGS® enterprise switches. The combination of the BCM5478 and StrataXGS or ROBOswitchTM provides a complete switching solution for the enterprise and small-to-medium-sized business (SMB) markets.

"Broadcom now has the lowest power octal Gigabit PHY in the industry which is key to enabling cost-effective 48-port or greater Gigabit switches, as well as SMB switches," said Nariman Yousefi, Vice President and General Manager of Broadcom's Networking Physical Layer/Optical Line of Business. "Broadcom has been able to extend its technology leadership by leveraging the experience that we've gained from two previous ASIC devices released to production, each containing eight 0.13-micron Gigabit PHYs."

To provide the most robust operation at Gigabit speeds, even over marginal cable plants, the BCM5478 octal transceiver incorporates the industry's most powerful DSP transceiver engine, with 20% more signal processing power than competitive solutions. The BCM5478 is designed to exceed IEEE specifications for noise cancellation and transmission jitter, providing consistent and reliable operation over the broadest range of existing cable plants.

The cable diagnostic capability integrated into the BCM5478 has been debugging cable plant issues since it was introduced with Broadcom's first Gigabit Ethernet PHY, and has been incorporated into six generations of field- proven technology. This diagnostic capability allows users, IT managers and networking equipment manufacturers to remotely analyze the quality and attributes of the cable, thereby avoiding unnecessary equipment returns and service calls. The built-in diagnostics help to pinpoint the cause of network malfunctions without the necessity to deploy field support personnel or to bring down the network.

Cable electrostatic discharge (CESD) is an issue that has become more prevalent with contemporary cable installations and occurs when an electrically charged network cable is plugged into a network port. The BCM5478 octal transceiver is part of a family of Broadcom transceivers with the industry's highest tolerance to CESD. A high tolerance to CESD has been particularly challenging in 0.13-micron transceivers in the past due to the small size of the transistors, but Broadcom's octal design and CESD tolerance help reduce the risk of system returns due to a CESD-damaged port. In addition, the BCM5478 has extremely low EMI emissions, which reduces the system design constraints required to meet EMI radiation specifications. Through the use of cost-effective magnetics, the BCM5478 also lowers overall system cost.

The BCM5478 is the latest member of Broadcom's 0.13-micron Gigabit Ethernet-over-copper PHY family, joining more than a dozen additional quad and single port PHY products. Broadcom has shipped more than 75 million Gigabit PHY ports to date, making its Gigabit transceivers most field-proven and reliable in the industry.

Pricing and Availability
The BCM5478 Gigabit Ethernet octal transceiver is currently available to all customers and is priced at less than $40 in quantities of 10,000 units.
