Device Overview

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

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 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.
