NetLogic Microsystems Introduces Comprehensive Portfolio of
Dual-Port 10-Gigabit Ethernet PHYs at Optical Fiber Communication
Conference and Exposition (OFC) 2008

NetLogic Microsystems' new AEL2020 dual-port SFP+ 10-Gigabit Ethernet PHY and AEL3020 dual-port 10GBASE-KR PHY are optimized for next-generation datacenter applications with the industry's lowest power, smallest package footprint and lowest latency.

Mountain View, Calif. – Feb. 26, 2008 – NetLogic Microsystems, Inc. [NASDAQ: NETL], the leader in the design and development of knowledge-based processors and high-speed integrated circuits, today introduced a portfolio of dual-port 10-Gigabit Ethernet (10GE) physical layer (PHY) products specifically optimized for advanced datacenter applications. These products will be showcased at the Optical Fiber Communication Conference and Exposition (OFC) 2008 Booth # 3248 in San Diego, Calif. this week. The dual-port 10GE PHY devices target both high-density SFP+ front-end applications and next-generation back plane applications. The new AEL2020 and AEL3020 devices, which are built in CMOS, integrate NetLogic Microsystems' industry-leading and market-proven Electronic Dispersion Compensation (EDC) technology, and are compliant with IEEE 802.3aq LRM and 802.3ap KR standards.

The popularity of Web 2.0 has led to an explosive growth in the amount and richness of content being generated by social networking, peer-to-peer (P2P) networking, video and music streaming portals. This trend, coupled with the broad worldwide availability of high-speed broadband services such as DSL, PON, cable modem, 3G/4G mobile access and Wi-Fi, are placing strenuous bandwidth requirements on existing datacenters. Next-generation datacenters need to deliver significantly higher performance and lower latency while meeting stringent energy efficiency and space requirements.

NetLogic Microsystems' new dual-port 10GE PHY products are ideally suited for these advanced datacenter applications. By featuring the industry's lowest power consumption, the industry's best-in-class latency which is 5X lower than competing digital solutions, and the industry's smallest footprint, NetLogic Microsystems' family of dual-port PHY products truly enable high-density 48-port 10GE SFP+ datacenter switches.

"With its new portfolio of dual 10GE PHY devices, NetLogic Microsystems has targeted the key metrics for optimal data center performance  power, latency and footprint," said Jag Bolaria, senior analyst at The Linley Group. "These vectors will differentiate these devices from competing solutions in the high-growth datacenter market segment. NetLogic Microsystems' products allow system designers to take advantage of these low power, short latency and small footprint offerings while easing the design process."

The AEL2020 features a number of advantages for use in high density SFP+ applications:

• Low-power limiting mode which substantially reduces power for SR/LR SFP+ applications to 800 milliwatts per port
• Industry-leading EDC technology that is field proven over the last 2 years and allows for IEEE 802.3aq LRM and direct-attach copper front ends
• Three taps of programmable transmit pre-emphasis on the 10GE transmitter with fine-grained control
• On-chip micro-controller per channel for flexible EDC control
• Support for 1Gbps data rates Variety of testability features which include Ethernet packet generators and checkers that allow customized frame generation and receive link margining capability for SFP+ link testing across PVT
• Available in the industry's smallest package

The AEL3020 is a dual-port device that has a XAUI system interface with a 10GBASE-KR compliant front end. Its unique features include:

• Industry-leading EDC technology that is field proven over the last 2 years
• FEC – Forward Error Correction compliant with the IEEE 802.3ap specification
• Auto-negotiation support as described in the IEEE 802.3ap specification
• Calibration of transmit equalizers with the help of training sequences on the receiver back channel
• On-chip micro-controllers for flexible EDC control
• Enhanced error statistics monitoring exceeding the IEEE 802.3ap specification
• Support for 1GBASE-KX mode

"We're excited to continue to lead the industry in all three key metrics – power, latency and footprint – with our new portfolio of dual-port PHY products targeted at next-generation datacenter designs," said Stefanos Sidiropoulos, vice president of Physical Layer Products at NetLogic Microsystems. "Our new products will enable a new class of high-density chassis-based linecards, rackmount switches and blade server cards to support media-rich applications."

The new dual-port AEL2020 and AEL3020 PHY devices from NetLogic Microsystems are currently sampling to select customers.
