Product Technical Specification & Customer Design Guidelines

Power supply noise

Noise in the power supply can lead to noise in the RF signal.

The power supply ripple limit for the module is no more than 200 mVp-p 1 Hz to

100

kHz. This limit includes voltage ripple due to transmitter burst activity.

Additional decoupling capacitors can be added to the main VCC line to filter noise

into the device.

SED (Smart Error Detection)

The module uses a form of SED to track premature modem resets.

• Module tracks consecutive resets occuring soon after power-on.

• After a sixth consecutive reset, the module waits in boot-and-hold mode for a

firmware download to resolve the power-cycle problem.
