Chapter: Overview Features
2 Overview
2.1 Features
The CB4052 is a highly complex computer motherboard in the PC/104™ form factor, complying with the
state-of-the-art "PCI/104-Express™" standard. It's based on Intel®'s GS45 chipset combined with the
ICH9M-E chip (SFF). Several CPUs are available for this board, all from Intel®'s Core™2 Duo and
Celeron® M series. Modern DDR3 technology provides top-notch memory performance, accomodating
up to 4 GByte of RAM (DDR3-1066) via SO-DIMM204. PCI bus and PCI-Express are available through
the PC/104-Plus and PCI/104-Express (type 1) connectors, respectively, giving system builders a great
deal of flexibility as far as expansion cards are concerned. Additional onboard peripheral devices include
two serial interfaces, two Gigabit Ethernet interfaces (LAN), four SATA channels, an audio interface (HDA
7.1), eight USB channels and CRT and LVDS/TFT support.

3 Connectors
This section describes all the connectors found on the CB4052.
CAUTION
For most interfaces, the cables must meet certain requirements. For instance, USB 2.0 requires twisted
and shielded cables to reliably maintain full speed data rates. Restrictions on maximum cable length are
also in place for many high speed interfaces and for power supply. Please refer to the respective
specifications and use suitable cables at all times.

Power Supply Chapter: Connectors
3.2 Power Supply
The power supply of the hardware module is realized via a 2x5-pin connector (Molex PS 43045-10xx,
mating connector: Molex PS 43025-10xx). Both 5V VCC/SVCC and 12V need to be provided. The 12V
input can optionally be tied to 5V if 12V is not required by attached peripherals. It cannot, however, be left
unconnected.
CAUTION
The CB4052 includes circuitry that will notify an intelligent power supply to shut down if the processor
reaches a critical temperature. This is achieved by deasserting the (low-active) PS_ON# signal found on
the SM-Bus connector. When PS_ON# is no longer pulled low, an intelligent power supply would take this
as a signal to shut down power. For this to work, PS_ON# must be connected to the power supply's
PS_ON input. If PS_ON# is not otherwise connected, the CB4052 can be damaged beyond repair if a
thermal shutdown event occurs. In rare instances, if power is not shut down, the board will continue to
heat up until failure occurs.
NOTE
Since this is a 90 degree connector, the symbol in the drawing below represents the connector face as
seen from the side (PCB on bottom) rather than from above.

Chapter: Connectors System
3.3 System
The system connector, which has the main functions that are necessary to start the board, is provided via
a standard IDC socket connector with a spacing of 2.54 mm.
This connector supports the following interfaces: PS/2 keyboard, PS/2 mouse, speaker, external
RTC-battery and reset of the board.
NOTE
For "Real Time Clock" an external battery (3.3V) must be connected. Connect "+" to VBAT and "-" to
GND.

Memory Chapter: Connectors
3.4 Memory
There is one conventional SO-DIMM204 socket available to equip the board with memory (DDR3-1066).
It is located on the bottom side of the board. For technical and mechanical reasons it is possible that
particular memory modules cannot be employed. Please ask your sales representative for recommended
memory modules.
With currently available SO-DIMM modules a memory extension up to 4 GByte is possible. The timing
parameters for different memory modules are automatically set by BIOS.
