Device Overview

of PCI Express® switching solutions. The PES64H16AG2 is a 64-lane,

16-port system interconnect switch optimized for PCI Express Gen2

packet switching in high-performance applications, supporting multiple

simultaneous peer-to-peer traffic flows. Target applications include

servers, storage, communications, embedded systems, and multi-host

or intelligent I/O based systems with inter-domain communication.

PES64H16AG2 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 89HPES64H16AG2 is a member of the IDT PRECISE™ family
