Description of the EB4T4

Eval Board

Introduction

The 89HPES4T4 switch (also referred toas PES4T4 inthis manual) is a member of IDT’s PCI Express®

standard (PCIe®) based line of products. It is an 4-lane, 4-port switch. One upstream port is provided for

connecting to the rootcomplex (RC), and up to three downstreamports areavailable for connectingto PCIe

endpoints or to another switch. More information on this device can be found in the 89HPES4T4 User

Manual.

The 89EBPES4T4 Evaluation Board (also referred to as EB4T4 in this manual) provides an evaluation

platform for the PES4T4 switch. It is also a cost effective way to add a PCIe downstream port (x1) to an

existing system with a limited number of PCIe downstream ports. The EB4T4 eval board is designed to

function as an add-on card to beplugged into a x1 PCIe slot available on a motherboard hosting an appro-

priate root complex, microprocessor(s), and three downstream ports. The EB4T4 is a vehicle to test and

evaluate the functionality of the PES4T4 chip. Customers can use this board to get a headstart on software

development prior to the arrival of their own hardware. The EB4T4 is also used by IDT to reproduce

system-level hardware or software issues reported by customers. Figure 1.1 illustrates the functional block

diagram representing the main parts of the EB4T4 board.
