7/24/2002 - Broadcom Corporation (Nasdaq: BRCM), the leading provider of integrated circuits enabling broadband communications, today announced that it is sampling the Broadcom® BCM5464S, the fifth member of its QuadSquad™ family of Gigabit quad transceivers optimized for high-port density Gigabit Ethernet switches and routers.
Broadcom's BCM5464S uses the industry's only 0.13-micron Gigabit physical layer (PHY) architecture in production, enabling industry leading power dissipation at less than 700-milliwatts per port, a 30% power reduction over Broadcom's existing Gigabit Ethernet PHYs. The BCM5464S solution greatly reduces system costs by simplifying typical high-density board designs, further facilitating the deployment of Gigabit Ethernet bandwidth to the desktop. Additionally, this device features a choice of reduced pin count SerDes (Serializer/Deserializer) or Serial Gigabit Media Independent Interfaces (SGMII) for the MAC interface, and a choice of copper or fiber for the media interface, offering system manufacturers design flexibility.
"Power dissipation is a critical factor limiting the design of 36-, 48- and 72-port networking systems," said Robert A. Rango, Vice President and General Manager of Broadcom's Network Infrastructure Business Unit. "Broadcom's new quad transceiver offers a dramatic improvement in power, while greatly reducing system costs for systems containing advanced switch ASICs with SGMII, such as Broadcom's StrataXGS™. With the BCM5464S and StrataXGS, two to six PCB layers can be eliminated, a significant cost savings to equipment manufacturers building these high-density designs."
The BCM5464S incorporates Broadcom's fifth-generation Gigabit Ethernet transceiver technology implemented in the advanced 0.13-micron CMOS process. This product joins Broadcom's existing family of Gigabit Ethernet transceivers that include the BCM5404, BCM5421, BCM5421S, BCM5414, BCM5424 and BCM5434.
Broadcom's DigiPHY™ Ethernet transceivers are the most widely deployed and field-proven in the industry, with over 4.5 million Gigabit ports shipped to date. Over 100 designs incorporating Broadcom's Gigabit PHYs have been announced and are shipping, and over 200 designs have been awarded and are under development.
BCM5464S Product Details
The on-chip SerDes interface provides a four-pin connection to the switch/MAC, while the SGMII interface is an alternative six-pin MAC/PHY interface. These reduced pin count interfaces simplify design and can lower system cost by reducing board layout constraints in high-density solutions. In addition, with these interfaces on the BCM5464S, fewer pins are required for the switch/MAC ASIC, which can reduce the switch/MAC cost by enabling smaller die sizes than would be possible with existing Gigabit Media Independent Interface (GMII) or Ten Bit Interfaces (TBIs).
Broadcom's StrataXGS family of Gigabit Ethernet switch devices takes advantage of the SGMII interface to offer triple speed functionality, while minimizing design complexity. For a 48-port system, using the SerDes interface instead of the traditional GMII interface can save over 1000 pins and 1000 traces, a reduction of 84%. Reduced routing between the StrataXGS switch ASIC and the BCM5464S removes 2 to 6 layers of the system level PCB, slashing board costs by 25 to 50 percent. The integration of this high-speed I/O technology minimizes chip count, simplifies board design, and reduces overall system cost.
A unique feature of the BCM5464S is its ability to support both copper and fiber networks, with an integrated SerDes PHY interface that can connect directly to a fiber optic module. Switching between copper and fiber media can be accomplished either automatically or through software control. For legacy switch/MACs, the BCM5464S supports the IEEE 802.3 standard GMII and Reduced GMII (RGMII) interfaces, with advanced timing mode. Broadcom's advanced timing solution provides a DLL-based delay for receive and transmit clocks, eliminating the need for timing delay traces required by the RGMII specification.
To provide robust operation at Gigabit speeds even over marginal cable plants, the BCM5464S incorporates the industry's most powerful transceiver DSP engine, with 20% more horsepower than competitive solutions. The BCM5464S 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. In addition, Ethernet@WireSpeed™ technology, a standard feature on Broadcom Gigabit PHYs for the last two years, enables equipment manufactured using the BCM5464S to auto-negotiate to the maximum speed possible over an impaired cable plant, regardless of the maximum speed advertised by the end equipment.
The BCM5464S's cable diagnostic capability has been helping debug cable plant issues since it was introduced with Broadcom's first Gigabit Ethernet PHY, the BCM5400. This diagnostic 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. Built-in diagnostics help pinpoint the cause of network malfunctions without deploying field support personnel or bringing down the network.
The BCM5464S Gigabit Ethernet-over-Copper Transceiver is currently sampling to Broadcom's early access partners and is priced at $55 in quantities of 10,000 units.
