The ExpressLane™ PEX 8604 device offers 4 PCI Express Gen 2 (5.0 GT/s) lanes, which supports up to four ports. The switch conforms to the PCI Express Base Specification, rev 2.0. The PEX8604 is the industry's smallest 4-lane Gen 2 device and it enables users with the ability to connect multiple PCI Express endpoints which are used in a variety of consumer and embedded applications including Multi-Function Printers, wireless ethernet modules, IO expansion modules, Express Card applications as well as other low power applications. The PEX 8604 boasts unsurpassed performance with its non-blocking architecture, capable of supporting both host-centric as well as true peer-to-peer traffic on its ports. The PEX 8604 supports x2 port width natively on the upstream port which allows it to interface directly and seamlessly to embedded processors commonly used in such applications. The PEX 8604 also features an on-chip Non-Transparent port for dual-host and failover applications, supports dual-clock domain operation by virtue of support for Spread Spectrum Clock (SSC) isolation as well as two Virtual Channels for enhanced QoS. The device is hardware configurable and/or software programmable, allowing users to tailor their port configurations and QoS operating characteristics to suit their application requirements. The PEX 8604 is offered in a 15 x 15mm 196-ball PBGA. This device is available in both leaded and lead-free packaging. This device supports Access Control Services (ACS).
