considerate must be kept into account that the capacitance mainly depends on the
application board.
Generally, additional capacitance is required when the power line is longer.
And if fast power down function is used, additional bypass capacitors should be mounted
on the application board.
EMC Recommendations
EMC protection on all the pins of LN920 should be designed by application side according
to the customer’s requirement.
ESD rating on all pins of LN920 Family :
Human Body Model (HBM): ± 1000 V
Charged Device Model (CDM): ± 250 V
All Antenna pins up to ± 4 kV
Warning: Do not touch the modem without proper electrostatic
protective equipment. The product must be handled with care,
avoiding any contact with the pins because electrostatic discharge
may damage the product itself.
