Features

PEX 8613

PCIe Gen 2, 5.0GT/s 12-lane, 3-port Switch

PEX 8613 General Features

o 12-lane, 3-port PCIe Gen 2 switch

- Integrated 5.0 GT/s SerDes

o 19 x 19mm², 324-pin PBGA package

o Typical Power: 1.74 Watts

The ExpressLane^TMPEX 8613 device offers PCI Express switching

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 8613 is

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

PEX 8613 Key Features

o Standards Compliant

- PCI Express Base Specification, r2.0

(backwards compatible w/ PCIe r1.0a/1.1)

- PCI Power Management Spec, r1.2

- Microsoft Vista Compliant

- Supports Access Control Services

- Dynamic link-width control

- Dynamic SerDes speed control

o High Performance

- Non-blocking switch fabric

- Full line rate on all ports

- Packet Cut-Thru with 140ns max packet

latency (x4 to x4)

- 2KB Max Payload Size

- Read Pacing (bandwidth throttling)

- Dual cast

o Flexible Configuration

- Registers configurable with strapping

pins, EEPROM, I²C, or host software

- Lane and polarity reversal

- Compatible with PCIe 1.0a PM

o Dual-Host & Fail-Over Support

- Configurable Non-Transparent port

- Moveable upstream port

High Performance & Low Packet Latency

The PEX 8613 architecture supports packet cut-thru with a maximum

latency of 140ns (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 8613 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.

- Crosslink port capability

o Dual-Clock Domain

- SSC clock isolation

o Quality of Service (QoS)

- Two Virtual Channels

Flexible Register & Port Configuration

The PEX 8613’s 3 ports can achieve link up to lane widths of x1, x2, or x4.

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

- Eight traffic classes per port

- Weighted round-robin source

port arbitration

o Reliability, Availability, Serviceability

- All ports Hot-Plug capable thru I²C

(Hot-Plug Controller on every port)

- ECRC and Poison bit support

- Data Path parity

- Memory (RAM) Error Correction

- INTA# and FATAL_ERR# signals

- Advanced Error Reporting

- Port Status bits and GPIO available

- Per port error diagnostics

can be changed dynamically.

The PEX 8613 also provides

several ways to configure its

registers. The device can be

configured through

PEX 8613

strapping pins, I²C

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

PEX 8613’s common port

configurations.
