Description of the EB16NT2

Eval Board

Introduction

The 89HPES16NT2 switch (also referred to as PES16NT2 in this manual) is a member of IDT’s PCI

Express® standard (PCIe®) based line of products.It is a 16-lane,2-port peripheral chip that provides high-

performance switching and non-transparent bridging (NTB) function between an upstream port and an NTB

downstream port.

The 89EBPES16NT2 Evaluation Board (also referred to as EB16NT2 in this manual) provides an evalu-

ation platform for the PES16NT2 switch. It is designed to functionas an add-on card to beplugged into a x8

PCIe slot available on a motherboard hosting an appropriate root complex, microprocessor(s), and an NTB

downstream port to be connected to another root complex, microprocessor(s) via a PCI Express cable. The

EB16NT2 is a vehicle to test and evaluate the functionality of the PES16NT2 chip. Customers can use this

board to get a headstart on software development prior to the arrival of their own hardware. The EB16NT2

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 EB16NT2 board.

Notes Board Features

Hardware

PES16NT2 PCIe 2-port Non-Transparent switch

– Two ports, 16 PCIe lanes

– PCIe Base Specification Revision 1.0a compliant

– 8 GBps (64Gbps) aggregate switching capacity

– Up to 2048 byte maximum Payload Size

– Automatic lane reversal and polarity inversion supported on all lanes

– Automatic per port link width negotiation to x8, x4, x2,x1

– Load configuration from an optional serial EEPROM via SMBUS

Upstream, Transparent/Non-Transparent Port

– One edge connector on the upstream port, to be plugged into a slot with x8 capable on a host

motherboard

– Transparent or Non-Transparent port via x8 PCI Express connector

Numerous user selectable configurations set using onboard jumpers and DIP-switches

SMBUS Slave Interface (4 pin header)

SMBUS Master Interface connected to the Serial EEPROMs through I/O expander

Push button for Warm Reset

Several LEDs to display status, reset, power, etc.

One 10-pin JTAG connector (pitch 2.54 mm x 2.54 mm)

Software

There is no software or firmware executed on the board in transparent mode. However, useful software

is provided along with the Evaluation Board to facilitate configuration and evaluation of the PES16NT2

within host systems running popular operating systems. In non-transparent mode, IDT provides Windows

XP or a Linux device driver for PES16NT2 Non-Transparent Bridge endpoints. This driver includes two

separate drivers, PCI endpoint driver and NDIS Ethernet miniport driver. Please contact [email protected]

for additional information.

Installation programs

– Operating Systems Supported: Windows2000, WindowsXP, Linux

GUI-based application for Windows and Linux

– Allows users to view and modify registers in the PES16NT2

– Binary file generator for programming the serial EEPROMs attached to the SMBUS.

Other

A metal bracket is required to firmly hold in place the four endpoints plugged into the EB16NT2

board.

SMBUS cable may be required for certain evaluation exercises.

SMA connectors are provided on the EB16NT2 board for specific test points.
