Sunnyvale, Calif.PLX Technology Inc. recently rolled out a pair of high-performance PCIe switches that are intended for control planes, back planes, gigabit Ethernet cards, host bus adapters, servers, enterprise storage, and multi-function printers.
The PLX ExpressLane PEX 8617 (16 lanes, four ports) and PEX 8613 (12 lanes, three ports) are PCI-SIG PCIe 2.0 (Gen 2) specification-compliant switches that feature the company's non-transparent (NT) port functionality. An NT port isolates the address domains between two hosts which in turn enables the switches' dual virtual channels (VCs) to provide two separate data paths for memory traffic (high and low priorities) with enhanced quality of service (QoS), regardless of CPU single VC limitations.
They also feature the company's integrated spread spectrum clock (SSC) isolation technology, which provides the capability for isolating the clock domains of two systems. SSC isolation allows designers the flexibility to develop products with asynchronous clock sources, thus removing the need for a single clock source for all PCIe components in a system.
Pricing: The PEX 8617 and PEX 8613 volume prices are $18.95, and $15.35, respectively.
Availability: Sampling today with full production in June 2009.
Datasheets: PEX 8617 and PEX 8613.
