Kontron User's Guide ETXexpress® CD 17
3.2 Mechanical Specifications
Dimensions
95.0 mm x 125.0 mm
Height approx. 12 mm (0.4”)
3.3 Electrical Specifications
Supply Voltage
12V DC +/- 5%
8.5V DC to 18V DC widerange input (see 2.2.2)
Supply Voltage Ripple
Maximum 100 mV peak to peak 0 – 20 MHz
Supply Current 5 V_SB
0,33 A in S5 mode
0,43 A in S0
Note: S3 cold will drive all the powersupply for memory refreshing and chip supply through the 5V_SB line.
Therefore up to 2A of current is specified for the connectors and should be in mind when the powersupply is
dimenstioned.
The board works also without a 5V_SB line but not the ACPI states S3 and S5.
3.3.1 Power Consumption
The maximum Power Consumption of the different COMe-bCD2 modules is between 18 - 40W (100% CPU
load; 90°C CPU temperature). Further details with measurements and TDP values of the single variants
can be found in our
customer section . Information there is available after registration.
All boards were equipped with DDR2 SDRAM. The Modules were tested using maximum CPU frequency.
