Description of the EB64H16
Eval Board
Foreword
This evaluation board manual includes hardware and software information on the 89HPES64H16,
89HPES48H12, and 89HPES48T12 peripheral chips. All three devices are members of IDT’s PRECISE™
family of PCI Express® switching solutions.
The 89HPES64H16 (PES64H16) is a 64-lane, 16-port switch and the 89HPES48H12 (PES48H12) is a
48-lane, 12-port switch. Both devices are system interconnect switches that perform PCI Express packet
switching with a feature set optimized for high-performance applications where multiple peer-to-peer traffic
flows are simultaneously transmitted.
The 89HPES48T12 (PES48T12) is a 48-lane, 12-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.
The same evaluation board is used for all three of these devices and, consequently, the information in
this manual applies equally, with some exceptions, to all three devices. Throughout the manual, numerous
references are made to the 89EBPES64H16 Evaluation Board (also referred to as EB64H16). These refer-
ences to the EB64H16 should be interpreted as also applying to both an EB48H12 board and an EB48T12
board, except where noted.
Introduction
The EB64H16 evaluation board provides an evaluation platform for the PES64H16 switch. The
EB64H16 has two x4 ports which can be merged to provide one x8 upstream port on a standard x16 PCI
Express connector. This port is used to connect an adaptor card with a cable to another adaptor card in the
root complex or host system. Alternatively, the upstream port can be defined as a x4 port allowing for fifteen
downstream ports
.
The downstream slots will conform to the x8 and x4 connector pin assignments but will be populated
with x16 connectors. The unused lane bits on the x16 connectors will be unconnected. The core and IO
power for the PES64H16 is derived from the 12V power supply connector from a 12VEPS type power
supply with a 24-pin connector and a 8-pin connector with 12V. The downstream slot power is controlled
through hot-plug controllers with power provided from the 12VEPS power supply connector with 12V. A
personality module is used to optionally merge two x4 ports into one x8 downstream port connector. The
PES64H16 Evaluation board block diagram is shown in Figure 1.1 and the PES48H12 / PES48T12 block
diagram is shown in Figure 1.2.
