PCE-5120 User Manual 2
Chapter 1 Hardware Configuration

1.1 Introduction

The PCE-5120 is designed with the Intel® 945G chipset and ICH7R (I/O
controller) to support Core™ 2 Duo, Dual-Core Pentium® D / Pentium®
4 / Celeron® D processors (refer to “Processor Support” on page vi) with
a 533/800/1066 MHz front side bus and DDR2 533/667 MHz memory up
to 4 GB. It follows the PICMG 1.3 specification and is the best solution
for high-performance computing and applications in which a wide I/O
bandwidth is demanded.
The PCE-5120 offers a high-performance cost-saving integrated graphics
unit, built into the Intel® 945G chipset, and features the unique Intel®
Extreme Graphics architecture to maximize VGA performance and share
system memory up to 224MB. Whenever higher graphics computing abil-
ity is required, the PCE-5120 also provides a mainstream PCI Express x
16 Link to the PICMG 1.3 backplane to interface add-on graphic cards. In
addition, the PCE-5120 has a single/dual Gigabit Ethernet LAN via dedi-
cated PCI Express x 1 bus, which offers bandwidths up to 500 MB/sec.,
eliminating the network data flow bottlenecks, and incorporating Gigabit
Ethernet to operate at 1000 Mbps. High reliability and outstanding perfor-
mance make the PCE-5120 the ideal platform for industrial networking
applications.
By using the Intel® ICH7R chipset, the PCE-5120 offers another four
PCI-Express x 1 Link to backplane which can be configured for support-
ing variety expansion slots. With four on-board SATA2 interfaces (band-
width = 300MB/sec), the PCE-5120 may support software RAID 0, 1, 5,
10 functions; eight USB 2.0 connections (four on board and four to back-
plane). These powerful I/O capabilities ensure even more reliable data
storage capabilities and suitable for work with high-speed I/O peripher-
als.
In addition, the PCE-5120 also provides most of the popular I/O inter-
faces such as one ATA-100 EIDE ports, AC'97 audio interface, four RS-
232 ports (COM2 port may be configured for supporting RS-232/422/485
through a pin header), one enhanced parallel port and floppy disk inter-
face.
