Because the STK-MBa53 is a development platform, no EMC specific tests have been carried out.
During the development of the STK-MBa53 the following standard was taken into account:
EMC-Interference radiation:
Measurement of the electrically radiated emission for standard, residential, commercial and light industrial environments in the
range of 30 MHz to 1 GHz according to DIN EN 55022 A1:2007.

Most of the interfaces on the STK-MBa53 are protected against electrostatic discharge13.
The interfaces, which provide an ESD protection is described in the corresponding paragraphs in section 4.
Following measures are recommended for a baseboard:
•
Generally applicable:
Shielding of the inputs
(shielding connected well to ground / housing on both ends)
•
Supply voltages:
Protection by suppressor diode(s)
•
Slow signal lines:
RC filtering, perhaps Zener diode(s)
•
Fast signal lines:
Integrated protective devices (suppressor diode arrays)

Reliability and service life
No detailed MTBF calculation has been done for the STK-MBa53. The STK-MBa53 is designed to be insensitive to vibration and
impact. Middle grade connectors, which guarantee at least 100 mating cycles, were used for the STK-MBa53.
The connector for the LVDS interface guarantees 30 mating cycles.
Information to the mating cycles of the remaining connectors can be looked up in the corresponding paragraphs in section 4.

WEEE regulation
The company placing the product on the market is responsible for the observance of the WEEE regulation.
To be able to reuse the product, it is produced in such a way (a modular construction) that it can be easily repaired and
disassembled.
