PLX Announces New 10GBase-T PHY Optimized for ToR Switches

(March 27, 2012)

SUNNYVALE, CA -- (Marketwire) -- 03/27/12 -- PLX Technology, Inc. (NASDAQ: PLXT), a leading global supplier of high-speed connectivity solutions enabling emerging data center architectures, today announced the TeraPHY® TN8045 10GBase-T transceiver, a quad-port physical layer (PHY) housed in an industry-leading small 25mm-square package that is space-optimized to allow for 12 devices to fit side-by-side in a standard 48-port 10 Gigabit Ethernet Top-of-Rack (ToR) switch. The PLX® TN8045 is also ideal for a wide range of applications beyond these high-density ToR switches, including multi-port network adaptors that cater to servers, multi-port switch uplinks, and media converters.

The PLX TN8045 quad-port 10GBase-T PHY offers the same industry-leading cutting-edge functionally and performance as the TN8044, which is housed in a larger 27mm-square package, except the TN8045 eliminates the XAUI interface. Designed using PLX's third generation of PHY on 40nm lithography node, the unique TN8045 features a 10GBase-KR backplane interface, enhanced Energy Efficient Ethernet (eEEE) support, and is the industry's only 10GBase-T PHY with on-chip MACSec security and encryption hardware. PLX also offers the most comprehensive and proven suite of electromagnetic interference (EMI) mitigation hardware.

According to Crehan Research, 10GBase-T ToR switch ports are expected to see in excess of a twenty-fold increase over the next two years. "Reduced power, price, and footprint on 10GBase-T PHYs are enabling cost-effective 48-port 10 Gigabit Ethernet ToR switches to address the impending bandwidth needs of both cloud providers and enterprises," said Seamus Crehan, president of Crehan Research.

"High-density ToR switches are quickly becoming the mainstay of modern data center architectures, and the new TeraPHY TN8045 is designed to provide state-of-the-art 10GBase-T capabilities to this class of switch," said Ron Cates, PLX vice president of marketing, networking products. "The new 25mm by 25mm packages fit perfectly behind an array of RJ45 connectors with integrated magnetics, providing the highest density possible."

10 Gigabit Ethernet is quickly replacing the ubiquitous 1 Gigabit Ethernet standard. Data centers are being enabled with this higher-speed connectivity via PLX's 10GBase-T technology due to its 10-fold performance increase, as well as its seamless use of low-cost standard copper Ethernet cabling, unique security features and energy efficiency value. 10GBase-T PHYs are a fundamental building block of common data center hardware, including Ethernet switches, network interface cards (NICs), and network adapters. PLX innovation enabled the industry's first 10GBase-T equipment, and its industry-leading 10GBase-T PHY portfolio is designed into numerous platforms. Increasingly power-efficient and feature-rich PLX PHYs designed on a 28-nanometer node are now in development.

Pricing, Availability
The new PLX TeraPHY TN8045 quad-port transceiver is scheduled to sample in May 2012. Volume pricing starts at $82.00.
