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 8616 is

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

High Performance & Low Packet Latency

The PEX 8616 architecture supports packet cut-thru with a maximum

latency of 150ns (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 8616 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

x8. 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 8616 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

8616’s common port

configurations.

The PEX 8616’s 4 ports can be configured to lane widths of x1, x2, x4, or
