GbE switches go 'green' for SMBs

Keywords:SMB applications  single-chip GbE switch  PHY 

Broadcom Corp. announces the industry's first family of lead-free 65nm single-chip GbE switch solutions for small-to-medium-sized business (SMB) applications. This highly integrated switch family includes 5-, 8-, 16- and 24-port configurations, with full Layer 2 (L2) switching to comply with the feature set and port density requirements of today's SMB networks. This chip family is designed to support low power modes and conform to industry standards, while using packaging materials free of lead and other harmful toxins, enabling 'green' switch products for the SMB market.

"Delivering products in 65nm process technology allows Broadcom to provide its SMB customers with a feature set that rivals that of large enterprise networks, but in a cost-effective manner," said Martin Lund, vice president and general manager of Broadcom's network switching business. "Our new SMB switch family has a level of integration, power consumption and intelligence that goes beyond that of previous generation products and underscores our commitment to reduce the environmental impact of networking equipment both in power consumption and manufacturing processes. Since the SMB market is a high-volume one, our ability to impact the environment in a positive manner is amplified and more substantial."

Octal GbE PHY
The BCM53310 series includes the BCM53313 (16-port) and the BCM53314 (24- port) and provides a complete GbE L2 switching solution for customers addressing the unmanaged and smart switch space.

This new series of switches is claimed to be the first in the industry to integrate a MIPS processor, Broadcom's 65nm octal GbE PHY core, as well as QSGMII connectivity. Support for the QSGMII interface is significant as next generation switches are expected to adopt this technology as the standard interface for external PHY connectivity. Having both an integrated octal GbE PHY and QSGMII interface allows Broadcom to offer switching solutions that reduce power consumption, design complexity and total system cost, creating an optimised platform for the cost-driven SMB market. Also offered with the BCM53310 series is Broadcom's BCM54684. The BCM54684, also in 65nm, is the industry's first stand-alone octal GbE PHY with QSGMII, according to Broadcom.

Low-power device
The BCM53310 series provides a 40% reduction in total system power that helps reduce overall system costs.

The series also offers a single platform that supports both 16- and 24-port GbE unmanaged and smart switch configurations. Broadcom's web-managed SmartPATH networking software, together with the BCM53310 series, provides SMB customers with a complete hardware and software solution. The new product series also implements unique, easy-to-use features such as AutoVoIP, which provides QoS to prioritise and differentiate voice packets on the network to enable support for VoIP phones. The AutoDoS feature monitors incoming packets for denial of service (DoS) frames, providing improved security by detecting DoS attacks.

Powerful devices
The BCM53118 is a single-chip, 8-port GbE switch solution that underscores Broadcom's leadership in the unmanaged SMB switch and router market. Also designed in 65nm process technology, the BCM53118 achieves unprecedented integration, performance and support for a full L2 feature set at an optimal price point. The BCM53118 provides a 30 per cent reduction in power in full traffic mode versus previous generation 8-port switch silicon solutions. The product can also automatically detect which ports are being utilised and scale the power consumption proportionately to save an additional 26% in power. This capability solves a universal need within the networking industry to lower the thermal and power consumption in switching devices, and ultimately provide end-users with a smaller, cooler device that takes up less space.

Announced in November 2007, the BCM53115 is a single-chip, 5-port GbE switch that enables the mass deployment of GbE connectivity to consumer electronic devices and home networking equipment. This intelligent switching solution has the industry's smallest footprint and also achieves a 30% reduction in power versus previous generation 5-port switch silicon solutions.

The 65nm Broadcom BCM53310 series and BCM53118 single-chip GbE solutions are now sampling to early access customers. The BCM53115 has been sampling since November 2007. The BCM54684 65nm octal GbE PHY with QSGMII is also sampling. Pricing is available upon request.
