NetLogic Supplies SerDes for Arista's Low-Latency Switch

NetLogic Microsystems supplied several key innovations in high-speed physical layer SerDes development that resulted in the world's lowest latency 10 Gigabit Ethernet (GbE) PHY solution used in Arista's next-generation data centers switch.


NetLogic Microsystems' new dual-channel AEL2020-LL PHY with integrated SerDes features an ultra low-latency of 70 nanoseconds (ns), which is nearly a half of existing solutions. In addition to the ultra low-latency, the AEL2020-LL PHY device offers the industry's lowest power consumption and supports multiple protocols and multiple media types – single-mode fiber (10GBASE-LR), multi-mode fiber (10GBASE-SR and 10GBASE-LRM), direct-attached copper (10GBASE-CR) and extended reach optics (10GBASE-ER).


"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."http://www.netlogicmicro.com
