C, or host software

The ExpressLane

capability enabling users to add scalable high bandwidth, non-blocking

interconnection to a wide variety of applications including

workstations, storage systems, communications platforms,

embedded systems, and intelligent I/O modules. The PEX 8612 is

well suited for fan-out, aggregation, and peer-to-peer applications.

High Performance & Low Packet Latency

The PEX 8612 architecture supports packet cut-thru with a maximum

latency of 170ns (x4 to x4). This, combined with large packet memory and

non-blocking internal switch architecture, provides full line rate on all ports

for performance-hungry applications such as servers and switch fabrics.

The low latency enables applications to achieve high throughput and

performance. In addition to low latency, the device supports a max payload

size of 2048 bytes, enabling the user to achieve even higher throughput.

Data Integrity

The PEX 8612 provides end-to-end CRC (ECRC) protection and Poison bit

support to enable designs that require end-to-end data integrity. PLX also

supports data path parity and memory (RAM) error correction as packets

pass through the switch.

Flexible Register & Port Configuration

Flexible buffer allocation, along with the device's flexible packet flow

control, maximizes throughput for applications where more traffic flows in

the downstream, rather than upstream, direction. Any port can be designated

as the upstream port, which

can be changed dynamically.

The PEX 8612 also provides

several ways to configure its

registers. The device can be

configured through

strapping pins, I

interface, host software, or

an optional serial EEPROM.

This allows for easy debug

during the development

phase, performance

monitoring during the

operation phase, and driver

or software upgrade. Figure

1 shows some of the

PEX 8612’s common port

configurations.

The PEX 8612’s 3 ports can be configured to lane widths of x1, x2, or x4.
