Electrical Specification; Supply Voltage - Kontron microETXexpress-SP User Manual

Table of Contents

All dimensions are shown in millimetres. Tolerances should be ± 0.25mm [±0.010"], unless otherwise noted. The

tolerances on the module connector locating peg holes (dimensions [16.50, 6.00]) should be ± 0.10mm [±0.004"].

The 220 pin connector shall be mounted on the backside of the PCB and is seen ―through‖ the board in this view. The 4

mounting holes shown in the drawing should use 6mm diameter pads and should have 2.7mm plated holes, for use

with 2.5mm hardware. The pads should be tied to the PCB ground plane. Gray circles represent the mechanical

mounting holes. Black circles represent the mounting holes required by the PICMG COM Express® standard.

Electrical Specification

8.5 V to 18 V DC in single supply mode

VCC + 5VSB ±5% in ATX mode (VCC > 5VSB)

Note:

If a module is E1 rated and should be used in E1 temperature range the supply voltage must be 12V +- 5%!

Power Supply Risetime

The input voltages shall increase from ≤10% of nominal to within the regulation ranges within 0.1ms to

20ms.

There must be a smooth and continuous ramp of each DC input voltage from 10% to 90% of its final set-point

following the ATX specification

Supply Voltage Ripple

Maximum 100 mV peak to peak 0-20MHz
