Device Overview

The 89HPES8NT2 is a member of the IDT PRECISE™ family of PCI

Express® switching solutions offering the next-generation I/O intercon-

nect standard. The PES8NT2 is a 8-lane, 2-port peripheral chip that

provides high-performance switching and non-transparent bridging

(NTB) functions between a PCIe® upstream port and an NTB down-

stream port. The PES8NT2 is a part of the IDT PCIe System Intercon-

nect Products and is intended to be used with IDT PCIe System

Interconnect Switches. Together, the chipset targets multi-host and intel-

ligent I/O applications such as communications, storage, and blade

servers where inter-domain communication is required.

Features

◆

High Performance PCI Express Switch

– Eight PCI Express lanes (2.5Gbps), two switch ports

– Delivers 32 Gbps (4 GBps) of aggregate switching capacity

– Low latency cut-through switch architecture

– Support for Max Payload size up to 2048 bytes

– Supports one virtual channel and eight traffic classes

– PCI Express Base specification Revision 1.0a compliant

◆

Flexible Architecture with Numerous Configuration Options

– Supports automatic per port link width negotiation (x8, x4, x2,

or x1)

– Static lane reversal on all ports

– Automatic polarity inversion on all lanes

– Supports locked transactions, allowing use with legacy soft-

ware

– Ability to load device configuration from serial EEPROM

– Ability to control device via SMBus

◆

Non-Transparent Port

– Crosslink support on NTB port

– Four mapping windows supported

• Each may be configured as a 32-bit memory or I/O window

• May be paired to form a 64-bit memory window

– Interprocessor communication

• Thirty-two inbound and outbound doorbells

• Four inbound and outbound message registers

• Two shared scratchpad registers

– Allows up to sixteen masters to communicate through the non-

transparent port

– No limit on the number of supported outstanding transactions

through the non-transparent bridge

– Completely symmetric non-transparent bridge operation

allows similar/same configuration software to be run

– Supports direct connection to a transparent or non-transparent

port of another switch

◆

Highly Integrated Solution

– Requires no external components

– Incorporates on-chip internal memory for packet buffering and

queueing

– Integrates eight 2.5 Gbps embedded full duplex SerDes, 8B/

10B encoder/decoder (no separate transceivers needed)
