SAFETY REQUIREMENTS AND PROTECTIVE REGULATIONS
6.1
EMC
The MBLX2160A was developed according to the requirements of electromagnetic compatibility (EMC). Depending on the target
system, anti-interference measures may still be necessary to guarantee the adherence to the limits for the overall system.
Following measures are recommended:
•
Robust ground planes (adequate ground planes) on the printed circuit board
•
A sufficient number of blocking capacitors in all supply voltages
•
Fast or permanently clocked lines (e.g., clock signals) should be kept short;
avoid interference of other signals by distance and/or shielding,
also pay attention to frequencies and signal rise times
•
Filtering of all signals, which can be connected externally
(also "slow signals" and DC can radiate RF indirectly)
6.2
ESD
A good protection against electrostatic discharge must be installed directly at the inputs of a system. On the MBLX2160A
common measures have been provided. The following measures are recommended for a carrier board:
•
Generally applicable:
Shielding of inputs (shielding connected well to ground / housing on both ends)
•
Supply voltages:
Suppressor diodes
•
Slow signals:
RC filtering, Zener diodes
•
Fast signals:
Protection components, e.g., suppressor diode arrays
6.3
Operational safety and personal security
Tests for operational safety and personal protection were not carried out due to the voltages ≤24 V DC.
