Introduction
2.1
Product Description
Introduction
COM Express modules are compact, highly integrated Single Board Computers.
Typically a COM Express module consists of CPU, chipset, memory, video controller,
Ethernet controller, BIOS flash and EIDE-, SATA- and USB controller. Interface
controllers (e.g. for PCMCIA) or connectors (e.g. RJ45) are implemented on the base
board on to which the COM Express module can be mounted via one or two 220-pin
SMD-connectors. Beside the power supply also signals for PCIe- and PCI-bus, EIDE,
SATA, USB, LPC etc. are present on these connectors.
The type of interfaces that is led from the COM Express module to the base board
depends on the type of module that is used. The COM Express specification defines five
different types which differ in number and pin assignment of the module connectors.
Thanks to the standardized mechanics and interfaces the system can be scaled
arbitrarily. In spite of a modular concept the systems design is very flat and compact.
COM Express modules require a base-board for successful operation.
The base board described below acts as an evaluation board for the COM Express
modules.

PCI Express x1 Slots
One PCIe x1 slot is assigned to each of the 6 PCIe lanes of the COM Express module.
Note: The order of the connectors has changed on the new layout. Now X6 is near PEG
slot.
Note : The number of PCIe lanes available will depend on the COM Express module
used – not all modules can support 6 PCIe lanes.

PCI Express x16 Graphics Slot
A PCIe x16 graphics slot is provided for insertion of PEG graphics cards.
Depending on the chipset the PCIe signals are multiplexed with SDVO signals, thus
SDVO modules can be run in this slot as well. SDVO or PCIe graphics will be activated
automatically via PullUps of the SDVO I²C interface on the SDVO module.

LVDS EEPROM
To store configuration data of the LCD, a serial EEPROM is connected to the signals
LVDS_I2C_CK and LVDS_I2C_DAT.
To avoid conflicts with configuration EEPROMs connected via the JILI connector, this
EEPROM can be assembled optionally.

CX-MB-EVA2 User's Manual
4.6.2
Hardware
Backlight Inverter Interface
The supply voltage of the backlight can be adjusted with jumper JP0601. The according
position is printed on the PCB.
Jumper J5 should be set according to the backlight inverter used.
If the inverter needs a low active start signal, jumper J5 has to be set to L (pin1
connected to pin2).
If the inverter needs a high active start signal, jumper J5 has to be set to H (pin2
connected to pin3).
Brightness of the backlight inverter is controlled via the LVDS-BKLT-CTRL signal.
The LVDS-BKLT-CTRL signal of the COM Express module is a PWM signal with current
chipsets. This signal is integrated and then limited to the maximum allowable voltage of
the backlight inverter via a voltage divider.
