OEM719 Power Requirements

Voltage

+3.3 VDC ±5%

Allowable Input Voltage Ripple

100 mV p-p maximum

Power Consumption

0.9 W typical, GPS L1 only

1.3 W typical, GPS L1/L2, GLONASS L1/L2

1.8 W typical, all constellations/all frequencies, plus L-Band

These are typical values using serial ports without interference mitigation. Values can change with the number of satellites in view, firmware version, data logging rates and features in use. Use them as a guide for what you might expect but not as absolute values.

LNA Power

+5.0 VDC ±5%, 0 mA to 200 mA (supplied by card through center conductor of RF connector).

LNA Power is generated from the 3.3 V supply input for the OEM719.

Pin 1 of P1701 is not electrically connected on the OEM719. This was the external LNA power input (LNA-PWR) on the OEM615.
