Device Overview

PCI Express® switching solutions. The PES64H16G2 is a 64-lane, 16-

port system interconnect switch optimized for PCI Express Gen2 packet

switching in high-performance applications, supporting multiple simulta-

neous peer-to-peer traffic flows. Target applications include servers,

storage, communications, embedded systems, and multi-host or intelli-

gent I/O based systems with inter-domain communication.

provides the most efficient system interconnect switching solution for

applications requiring high throughput, low latency, and simple board

layout with a minimum number of board layers. Each lane is capable of 5

GT/s of bandwidth in both directions and is fully compliant with PCI

Express Base specification 2.0.

Features

The 89HPES64H16G2 is a member of the IDT PRECISE™ family of

Utilizing standard PCI Express Gen2 interconnect, the PES64H16G2
