89HPES32H8

Data Sheet

32-Lane 8-Port PCI Express®

System Interconnect Switch

◆

Flexible Architecture with Numerous Configuration Options

Device Overview

–

Port arbitration schemes utilizing round robin algorithms

Virtual channels arbitration based on priority

Automatic per port link width negotiation to x8, x4, x2 or x1

Automatic lane reversal on all ports

Automatic polarity inversion on all ports

Supports locked transactions, allowing use with legacy soft-

ware

The 89HPES32H8 is a member of the IDT PRECISE™ family of PCI

Express® switching solutions. The PES32H8 is a 32-lane, 8-port system

interconnect switch optimized for PCI Express packet switching in high-

performance applications, supporting multiple simultaneous peer-to-

peer traffic flows. Target applications include servers, storage, communi-

cations, and embedded systems.

Features

–

Ability to load device configuration from serial EEPROM

Ability to control device via SMBus

◆

High Performance PCI Express Switch

◆

–

Eight maximum switch ports

Highly Integrated Solution

• Four main ports each of which consists of eight SerDes

• Each x8 main port can further bifurcate to 2 x4-ports

Thirty-two 2.5 Gbps embedded SerDes

–

Requires no external components

Incorporates on-chip internal memory for packet buffering and

queueing

–

• Supports pre-emphasis and receive equalization on per-port

basis

–

Integrates thirty-two 2.5 Gbps embedded full duplex SerDes,

8B/10B encoder/decoder (no separate transceivers needed)

◆

–

Delivers 128 Gbps (16 GBps) aggregate switching capacity

Low-latency cut-through switch architecture

Support for Max Payload Size up to 2048 bytes

Supports two virtual channels and eight traffic classes

PCI Express Base Specification Revision 1.1 compliant

Reliability, Availability, and Serviceability (RAS) Features

–

Redundant upstream port failover capability

Internal end-to-end parity protection on all TLPs ensures data

integrity even in systems that do not implement end-to-end

CRC (ECRC)
