Device Overview

PCI Express® switching solutions. The PES34H16G2 is a 34-lane, 16-

port peripheral chip that performs PCI Express packet switching with a

feature set optimized for high-performance applications such as servers,

storage, and communications/networking. It provides connectivity and

switching functions between a PCI Express upstream port and up to

fifteen downstream ports and supports switching between downstream

ports.

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 89HPES34H16G2 is a member of the IDT PRECISE™ family of

Utilizing standard PCI Express Gen2 interconnect, the PES34H16G2
