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 function as an add-on card to be plugged 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.
