  • Page 7 Initialization The GXB5005 has a reset pin (Pin 16) and normally this pin should be left open. The GXB5005 can perform the power-on reset operation only by turning on or off the power supply pin (Pin 17). In addition, when configuring the component in order to realize the reset from the system side during operation, connect the reset pin to the external circuit.

  • Page 9: Uart Interface

    1 bit NMEA0183 Format The GXB5005 can output 8 different types of sentence: GPGGA, GPGLL, GPGSA, GPGSV, GPRMC, GPVTG, GPZDA and PSGSA. If 9600bps, 19200bps or 38400bps baud rate is set for port setting, it outputs 7 types of sentence: GPGGA, GPGSA, GPGSV, GPRMC, GPVTG, GPZDA and PSGSA as default. Moreover, if 4800bps baud rate is set, it outputs 4 types of sentences: GPGGA, GPGSA, GPGSV and GPRMC as default.
  • Page 10: 1Pps Output

    GXB5005 1PPS Output The 1PPS output provides a timing pulse synchronized to GPS time once a valid fix is available. The figure below shows the behavior of the 1PPS output signal after reset. For a period of 160μs after reset, the 1PPS signal outputs the system clock.
  • Page 11: Backup Mode

    GXB5005 Backup Mode The backup mode is established by setting all inputs Low except for B.U. (Vbat: 2.6 to 3.0V). In this mode, the low power consumption can be achieved by stopping all oscillators except for RTC oscillator. Although all registers are initialized, the SRAM for both of Ephemeris data and Almanac data in backup area are held.
