The power-on time of any interface of the module must not be earlier than the boot time

of the module, otherwise the module may be abnormal or damaged.

5.5 Electrostatic property

There is no overvoltage protection inside the CLM920 NC3 module. The ESD protection

is required when the module is used to ensure product quality.

EMC design recommendations

：



The USB port needs to add TVS on VDD, D+, D- for protection, and the TVS parasitic
capacitance on D+/D- is < 2 pF.



The module's USIM card external pin needs to be TVS protected for parasitic capacitance
requirements < 10 pF.



At the module input power supply, increase the TVS. It is recommended that the clamp
voltage VCL (Clamping Voltage) is less than 12 V and the peak power PPP (Peak Pulse
Power) is not less than 100 W.



The protective device PCB layout should be as close as possible to the

“

”

shaped line

to avoid the

“

”

shaped line.



The ground plane around the module guarantees integrity and should not be split.



ESD control of the surrounding environment and operators needs to be paid during
module production, assembly and laboratory testing.
