4.8 EMI/RFI and ESD Protection
The BitsyXb board incorporates a number of industry-leading features that protect it from
electrostatic discharge (ESD) and suppress electromagnetic and radio-frequency interference
(EMI/RFI). Transient voltage suppressors, EMI fences, filters on I/O lines and termination of
high-frequency signals are included standard on all systems. For details, see electrical
specifications for subsystems of interest.
4.8.1 Agency Certifications
Many products using Eurotech single-board computers have successfully completed FCC and CE
emissions testing as a part of their design cycle. Because Eurotech supplies only the single-board
computer and not fully integrated systems, Eurotech cannot provide meaningful system-level
emissions test results.
See the crystal frequencies (section 6.3.10) and electrical specifications for information that may
be helpful during agency certifications.
4.8.2 Protecting the Power Supply Inputs
It is the responsibility of the designer or integrator to provide surge protection on the input power
lines. This is especially important if the power supply wires will be subject to EMI/RFI or ESD.
