Low-Power 8-Lane, 8-Port ExpressLane

The PEX 8509 device offers PCI Express switching capability conforming to the

PCI Express Base specification revision 1.1. This device enables users to add

scalable high bandwidth, non-blocking interconnects at the lowest cost to a wide

variety of applications including communications platforms, consumer products,

servers, storage systems, blade servers, industrial systems and embedded-control

products. The PEX 8509 can be used as a fan-out, aggregation, or peer-to-peer

switch, and is well-suited for Control Plane Applications, Docking Stations,

DVRs, Multi-Function Printers, Industrial Control Systems, Medical Imaging

Systems, Embedded Systems and AMC modules.

Port Configurations

The PEX 8509 offers eight lanes and up to eight ports supporting x1, x2 and x4 lane

widths. The ports can be configured for symmetric (each port having the same lane

width and traffic load) or asymmetric (ports having different lane widths). In the

event of asymmetric traffic, the PEX 8509 features a flexible central packet

memory that allocates a memory buffer for each port as required by the application

or endpoint. This buffer allocation along with the device's flexible packet flow

control minimizes bottlenecks when the upstream and aggregated downstream

bandwidths do not match (are asymmetric).

High Performance

The PEX 8509 architecture supports packet cut-thru with low latency (118ns).

This, combined with large packet memory (up to 1024 byte maximum payload

size) and non-blocking internal switch architecture, provides full line rate on all

ports for performance hungry applications such as docking stations, control planes,

embedded systems and AMC modules.

End-to-End Packet Integrity

The PEX 8509 provides end-to-end CRC protection (ECRC) and Poison-bit

support to enable designs that require end-to-end data integrity. These features are

optional in the PCI Express specification, but PLX provides them across its entire

ExpressLane switch product line.

Configuration Flexibility

The PEX 8509 provides several ways to configure its operations. The device can be

configured through strapping pins, I

optional serial EEPROM. This allows for easy debug during the development phase,

performance monitoring during the operation phase, and driver or software upgrade.

Interoperability

The PEX 8509 is designed to be fully compliant with the PCI-SIG PCI Express base

specification revision 1.1. Additionally, it supports auto-negotiation, lane reversal,

and polarity reversal. The PEX 8509 also undergoes extensive Interoperability

testing in PLX’s Interoperability Lab.

Low Power with Granular SerDes Control

The PEX 8509 provides low power capability that is fully compliant with the PCI

Express power management specification. For even lower power, the SerDes

physical links can be programmed for desired power or turned off when unused.
