74.3.1
General precautions
The following module interfaces can have a critical influence in ESD immunity testing, depending
on the application board handling. The following precautions are suggested:
HW_SHUTDOWN pin (FW75-C200 only)
Sensitive interface is the reset line (HW_SHUTDOWN pin):
A 47 pF bypass capacitor (e.g. Murata GRM1555C1H470JA01) have to be mounted on the line
termination connected to the HW_SHUTDOWN pin to avoid a module reset caused by an
electrostatic discharge applied to the application board enclosure
A series ferrite bead (e.g. Murata BLM15HD182SN1) must be added on the line connected to
the HW_SHUTDOWN pin to avoid a module reset caused by an electrostatic discharge applied
to the application board enclosure
It is recommended to keep the connection line to HW_SHUTDOWN as short as possible
Reset_N pin (LISA-C200 only)
Sensitive interface is the reset line (Reset_N pin):
A 47 pF bypass capacitor (e.g. Murata GRM1555C1H470JA01) have to be mounted on the line
termination connected to the Reset_N pin to avoid a module reset caused by an electrostatic
discharge applied to the application board enclosure
