NetLogic Microsystems offers low-latency 10 Gigabit Ethernet PHY
NetLogic Microsystems, Inc. (NASDAQ: NETL) says its new dual-channel AEL2020-LL 10 Gigabit Ethernet (GbE) PHY with integrated serializer/deserializer (SerDes) features a latency of 70 nsec, a figure the company asserts is nearly a half that of competing chips.
NetLogic Microsystems, Inc. (NASDAQ: NETL) says its new dual-channel AEL2020-LL 10 Gigabit Ethernet (GbE) PHY with integrated serializer/deserializer (SerDes) features a latency of 70 nsec, a figure the company asserts is nearly a half that of competing chips. The AEL2020-LL PHY also offers the industry’s lowest power consumption, NetLogic Microsystems says.
The low-latency AEL2020-LL PHY supports multiple protocols and media types, including singlemode fiber (10GBase-LR), multimode fiber (10GBase-SR and 10GBase-LRM), direct-attached copper (10GBase-CR), and extended reach optics (10GBase-ER). The device is designed to provide full Physical Coding Sublayer (PCS), PMA, and XGXS sub-layer functionality through the consolidation of the receiver and transmitter PHY functions on a single chip.
The device also integrates encode/decode/alignment logic, FIFOs, on-chip clock generation and data recovery, multiple loop-back features, PRBS Ethernet frame generation and verification for both the line- and the system-side. The AEL2020-LL features packet, Pseudo Random Binary Sequence (PRBS), CJPAT, and CRPAT generators and checkers; Management Data Input/Output (MDIO), Joint Test Action Group (JTAG), SDA/SCL physical interfaces; and is available in RoHS 5/6 and RoHS 6/6 package options.
“As the leading provider of ultra-low latency 10 Gigabit Ethernet switches for clouds and data centers, we are very pleased with NetLogic Microsystems' continued technical leadership in reducing PHY latency,” said Andy Bechtolsheim, chairman and chief development officer at Arista Networks. "Our close collaboration with NetLogic Microsystems has been key to achieve the lowest Ethernet switch latency in the industry.”
“Achieving 70-nsec latency in 10GE PHY with integrated SerDes while maintaining low power consumption is no simple feat,” said Jag Bolaria at The Linley Group. “This innovative design is very positive for an industry that is increasingly migrating to cloud-based applications in the data center, and should help NetLogic Microsystems maintain its market and technology leadership in 10-to-100 GbE PHYs.”
