Introduction

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 intelli-
gent I/O based systems with inter-domain communication.
Utilizing standard PCI Express Gen2 interconnect, the PES64H16G2 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 direc-
tions and is fully compliant with PCI Express Base specification 2.0.
