Integrator’s Reference Manual

Caution You CANNOT have both a DC power supply and an AC adapter connected to the modem at the same time. This may cause the modem

to fail to power up and may damage the modem. If you connect the Diagnostic cable to service-program the modem while using a DC power source, make sure the AC wall adapter of the Diagnostic cable is not plugged in to an AC outlet.

Surge Protection

As an OEM, you are responsible for ensuring that the input voltage specification will never be exceeded.

Minimal transient protection is provided on the GSP-1620 modem board but this is intended only for low energy/duration events (total transient power less than 1 kW). It is not intended to protect the modem in case of a sustained over-voltage/lightning condition.

The use of a fuse is strongly recommended in the power supply connecting to the GSP-1620 modem. The input surge current requirements of the GSP-1620 modem are such that a fuse with a minimum melting I2t rating of 0.02 A2 seconds will be sufficient.

EMI Filtering

Adequate conducted EMI filtering has already been provided in the GSP-1620 modem to pass FCC and ETSI limits. Additional filtering should not be necessary to meet these requirements.

Caution Should additional filtering be necessary, you must take precautions to ensure that the above criteria are not violated. Please contact

QUALCOMM Incorporated for further details in such a case.

Power Consumption

Power consumption depends on a variety of factors such as transmit power, input voltage, and data rate. Table 7-3 summarizes the power consumption of the GSP-1620 modem at an input voltage of +12 V DC. All power estimates include
