Low latency PHY aimed at cloud applications
With the strong growth in cloud computing, large data centers, high-frequency financial trading, online advertisement insertion and high-performance computing, the response time or latency of the network becomes one of the most critical elements in data center performance.
These applications require dramatically lower latency to significantly improve user experience and financial profits. Every nanosecond of latency in the data center, for example, can make a major difference in price points on a large trading exchange in the financial industry.
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).
The AEL2020-LL dual-channel PHY device provides 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 along with the integration of 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 device also 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.
