The ExpressLane

enabling users to add scalable high bandwidth non-blocking interconnection to a

wide variety of applications including control planes, communication platforms,

servers, storage systems and embedded systems. The PEX 8618 is well suited for

fan-out, aggregation, peer-to-peer, and intelligent I/O module applications

Low Packet Latency & High Performance

The PEX 8618 architecture supports packet cut-thru with a maximum latency of

140ns. This, combined with large packet memory and non-blocking internal switch

architecture, provides full line rate on all ports for low-latency applications such as

communications and servers. 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 throughout

Data Integrity

The PEX 8618 provides end-to-end CRC protection (ECRC) and Poison bit support

to enable designs that require guaranteed error-free packets. PLX also supports

data path parity and memory (RAM) error correction as packets pass through the

switch

Dual-Host and Fail-Over Support

The PEX 8618 supports full non-transparent bridging (NTB) functionality to allow

implementation of multi-host systems and intelligent I/O modules in applications

which require redundancy support such as communications, storage, and servers.

Non-transparent bridges allow systems to isolate host memory domains by

presenting the processor subsystem as an endpoint rather than another memory

system. Base address registers are used to translate addresses; doorbell registers are

used to send interrupts between the address domains; and scratchpad registers are

accessible from both address domains to allow inter-processor communication

Interoperability

The PEX 8618 is designed to be fully compliant with the PCI Express Base

Specification r2.0 and is backwards compatible to PCI Express Base Specification

r1.1 and r1.0a. Additionally each port supports auto-negotiation, lane reversal and

polarity reversal. Furthermore, the PEX 8618 is designed for Microsoft Vista

compliance. All PLX switches undergo thorough interoperability testing in PLX’s

Interoperability Lab and compliance testing at the PCI-SIG plug-fest to ensure

compatibility with PCI Express devices in the market.

Device Operation Configuration Flexibility

The PEX 8618 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

and functional monitoring during the operation phase
