BROADCOM UNVEILS PCI EXPRESS GIGABIT ETHERNET CONTROLLERS.
For the past 10 years, the PCI bus architecture has been ubiquitously deployed as a system I/O interconnect technology. However, as processors, memory and other devices in the PC scale to increasingly faster speeds, it has become necessary for interconnect technology to advance as well. PCI Express is an advanced version of the current PCI bus that provides a standards-based, high-speed, low pin count, chip-to-chip interface for computing platforms. Rather than utilizing a shared, parallel bus structure such as with PCI or AGP, PCI Express provides a new architecture whereby each link is a serial communications channel comprised of two differential wire pairs that provide 2.5 Gigabits per second (Gbps) of throughput in each direction. The new standard is the natural evolution of the AGP, PCI and PCI-X standards used today. Its low pin count enables a new generation of small form fact or computing devices through smaller motherboards, while its speed capabilities reduce bottlenecks typically associated with current PCI and AGP solutions.
"As enterprise servers and clients migrate to increasingly faster Ethernet speeds, PCI Express allows the LAN connection architecture to scale with the end-users' throughput requirements. The BCM5721, BCM5751 and BCM5751M are the industry's first and only Gigabit Ethernet controllers designed specifically to address the needs of today's high-performance computing platforms," said Thomas Lagatta, group vice president for Broadcom's Enterprise Computing Group. "Based on our SerDes expertise and six prior generations of field-proven NetXtreme technology, this new family of GbE controllers is the most advanced GbE solution in the market today."
"Gigabit Ethernet has become the mainstream LAN technology used throughout the business world today," said Sean Lavey, semiconductor program manager for IDC. "We expect the support for PCI Express within GbE controllers will accelerate this adoption as it enables new types of PC and server form factors while dramatically increasing network performance."
The BCM5721 for High Performance Servers
Broadcom's new NetXtreme BCM5721 GbE controller is targeted at server platforms. Combining performance enhancements with a PCI Express 1x host interface, the BCM5721 enables 2 Gbps throughput for the most demanding server applications. To reduce the total cost of server ownership, the BCM5721 supports the Intelligent Platform Management Interface (IPMI) 1.5 manageability standard that allows servers to be remotely managed. The BCM5721 also incorporates the industry's most advanced server software (the Broadcom Advanced Server Program or BASP) which offers several teaming functions not available from any other GbE controller solution.
The BCM5751 for Desktop and Workstation PCs
Broadcom's BCM5751 is designed for use with desktop and workstation PCs and has been optimized to provide the industry's best price and performance combination. The BCM5751 provides significant advances in client manageability by adding support for the Alerting Standards Forum (ASF) 2.0 specification. This provides IT professionals with automatic alerts when support issues occur and allows them to remotely address these concerns.
The BCM5751M for Mobile PCs
Broadcom's BCM5751M GbE controller has been optimized for the tight space constraints of mobile PCs, enabling the industry's smallest footprint. In addition, the BCM5751M can sense how the mobile PC is being utilized and will reduce the power down to the lowest level necessary for that usage. Whether docked or mobile, transmitting data or not, the BCM5751M's advanced power management logic provides six power-down modes to always use the lowest power possible, extending battery life. Through an integrated Trusted Platform Module (TPM), the BCM5751M also includes support for the Trusted Computing Group 1.1b specification, offering security features and strong authentication to protect corporate information from attack.
Additional Product Information
Built upon six generations of field-proven Gigabit Ethernet media access controller (MAC) and physical layer (PHY) transceiver technology, the BCM5721 , BCM5751 and BCM5751M utilize a fully integrated 10/100/1000BASE-T Gigabit Ethernet MAC, PCI Express bus interface, on-chip buffer memory, and integrated PHY in a single-chip solution designed specifically for LAN on motherboard (LOM) and network interface card (NIC) applications. These three chip s are fabricated in a low-voltage, 0.13-micron CMOS process that provides low power consumption.
The three new devices include a comprehensive software suite offering a complete solution for client and server applications, including drivers for all popular operating systems. The NetXtreme architecture also features a unique processor-based design, enabling advanced management software to run in firmware so it can be remotely upgraded via simple downloads.
Broadcom's new family of NetXtreme PCI Express controllers complement the company's Gigabit Ethernet networking product portfolio that includes switching solutions, transceivers, and security processors for servers, workstations, desktops and mobile PCs, providing the industry's most comprehensive portfolio of Gigabit Ethernet solutions. Broadcom's Gigabit Ethernet solutions are the most widely deployed and field-proven in the industry.
