Product Brief

12 Lane 3-Port

PCI Express® Switch

◆

Flexible Architecture with Numerous Configuration Options

Device Overview

The 89HPES12N3A, a 12 lane 3-port PCI Express® switch, is a

member of the IDT PRECISE™ family of PCI Express switching solu-

tions. The PES12N3A is a peripheral chip that performs PCI Express

Packet switching with a feature set optimized for high performance

applications such as servers and storage. It provides connectivity and

switching functions between a PCI Express upstream port and two

downstream ports or peer-to-peer switching between downstream ports.

–

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

Automatic lane reversal on all ports

Automatic polarity inversion on all lanes

–

Ability to load device configuration from serial EEPROM

◆

Legacy Support

–

PCI compatible INTx emulation

Bus locking

The 89HPES12N3A offers an enhanced architecture and feature set

in a package that is pin-compatible with the first generation

89HPES12N3 12-lane, 3-port PCIe switch.

Highly Integrated Solution

–

Requires no external components

–

Incorporates on-chip internal memory for packet buffering and

queueing

Features

◆

–

Integrates twelve 2.5 Gbps embedded SerDes with 8B/10B

encoder/decoder (no separate transceivers needed)

High Performance PCI Express Switch

–

Twelve 2.5Gbps PCI Express lanes

Three switch ports

◆

Reliability, Availability, and Serviceability (RAS) Features

–

Supports ECRC and Advanced Error Reporting

Upstream port configurable up to x4

Downstream ports configurable up to x4

Low-latency cut-through switch architecture

Support for Max Payload Sizes up to 2048 bytes

One virtual channel

–

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

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

CRC (ECRC)

–

Supports PCI Express Native Hot-Plug, Hot-Swap capable I/O

Compatible with Hot-Plug I/O expanders used on PC and

server motherboards

Eight traffic classes

PCI Express Base Specification Revision 1.1 compliant
