Overview
2 OVERVIEW
2.1 FACE Module Concept
The CompuLab product line of industrial PCs is designed to support custom functionality and I/O
extensions with FACE (Function And Connectivity Extension) modules.
FACE modules are implemented by an internal extension board and a simple sheet-metal panel. The
extension board is connected to the PC motherboard with two board-to-board connectors featuring
standard PC interfaces such as PCIe, USB2, SATA, SMBus etc.
This document outlines the FACE module interface specification and custom FACE module design
requirements and recommendations.

FACE_PRSNT#

I
FACE module presence
detection. Must be connected
to GND.
PWR_BTN#
PX1-A43
I
Power button - causes an SMI
or SCI to indicate a system
request to enter a sleep state. If
the system is already in a sleep
state, this signal will cause a
wake event. If PWR_BTN# is
asserted for more than 4
seconds, it will cause an
unconditional transition (power
button override) to the S5 state
with only the PWR_BTN#
available as a wake event.
Override will occur even if the
system is in the S1 state. This
signal has an internal pull-up
resistor.
SLEEP_S3#
PX1-B43
O
S3 sleep power plane control.
Assertion of SLP_S3# shuts
off power to non-critical
components when system
transitions to S3, S4, or S5
states. De-assertion of
SLP_S3# turns on power to
non-critical components when
system transitions from S3, S4,
or S5 back to S0.

Electrical design recommendations
5 ELECTRICAL DESIGN RECOMMENDATIONS
5.1 General Design Guidelines
Ensure that all VCC and GND power pins are connected.
Major power rails – VCC and GND must be implemented by planes, rather than by traces. Using
at least two planes is essential to ensure the system signal quality, as the planes provide a current
return path for all interface signals.
It is recommended to put several 100nF and 10/100uF capacitors between VCC and GND near
the FACE module interface connectors.
It is recommended to connect the standoff holes of the baseboard to GND, in order to improve
EMC.
Trace impedance of 50-55 Ω ± 15% should be maintained for single-ended signals unless
specified otherwise.
Pay attention to the current return paths (which are as important as the routing), length matching,
and signal spacing to maintain proper signal integrity.
Maintain a solid power and ground reference plane, and do not route high-speed signals across
plane splits. If plane-crossing is absolutely unavoidable, use a high frequency stitching capacitor
Refer to the reference schematic designs available in the FACE module design package.
5.2 PCIe Design Guidelines
One AC coupling (series) capacitor of 100nF is required on each PCIe receive signal.
AC coupling (series) capacitors for PCIe transmit and clock signals are located on the fit-PC3
motherboard. No capacitors are required on the FACE module PCB.
Capacitor packs are not allowed for AC coupling. Use only discrete capacitors.
The AC coupling capacitors should be located as close as possible to the PCIe device.
Target impedance for PCIe differential pairs should be 85 Ω ± 15%.
Trace spacing should be ≥ 4:1 on both sides of the pair.
Avoid stubs or test points on the signal pairs.
Please refer to the reference schematics and layout designs available in the FACE module design
package.
5.3 SATA Design Guidelines
AC coupling (series) capacitors for SATA signals are located on the fit-PC3 motherboard. No
capacitors are required on the FACE module PCB.
Target impedance for SATA differential pairs should be 90 Ω ± 10%.
Trace spacing should be ≥ 5:1 on both sides of the pair.
Avoid stubs or test points on the signal pairs.
Please refer to the reference schematics and layout designs available in the FACE module design
package.

Electrical design recommendations
5.4 USB Design Guidelines
No termination resistors are required.
Target impedance for USB differential pairs should be 90 Ω ± 15%.
Trace spacing should be ≥ 4:1 on both sides of the pair.
Avoid stubs or test points on the signal pairs.
Provide ESD suppression components for any USB pair that is accessible to the end user, and
optionally for any USB pair that is not accessible to the end user. No stubs are allowed from the
USB signals to the ESD components. Place these components between the common mode choke
and connector. It is recommended to place ESD suppression components as close as possible to
the connector and at no further than 0.5” from the connector body.
Decouple the ESD suppression component with a high frequency capacitor placed directly across
the device power and GND pins, no further than 50 mils away.
Provide the option for a common mode choke for EMI suppression for any USB pairs that can be
connected to cabled devices. The chokes should be bypassed with 0-Ω resistors by default. The
resistors must be located under the choke to minimize stubs. Place the choke within 1.0” of the
USB connector.
Please refer to the reference schematics and layout designs available in the FACE module design
package.
5.5 Power Supplies Design Guidelines
Implement FACE module power supply rails with DC-DC switching regulators.
12V power rail should be used to supply the FACE module DC-DC switching regulators.
Maximal current consumption from the 12V power rail should not exceed 1A.
Maximal current consumption from the 5V power rail should not exceed 2A.
SLP_S3# signal may be utilized to implement power supply control. Please note SLP_S3#
polarity requirements.
Please refer to the reference schematics and layout designs available in the FACE module design
package.
