Page 15: Quick Start
3 Quick Start In order to allow an easy and quick start with the A5100-A module, this chapter pro- vides a short overview on the important steps to be taken to receive NMEA messages with position information on a serial port (UART). -
Page 16: Figure 6: Minimum Configuration A5100-A With Vbak
3: Quick Start Figure 6 shows the minimum configuration for NMEA outputs and commands sent via an RS232 interface based on the GPS/GLONASS module A5100-A using a pas- sive antenna and with backup voltage on V_BAK. Before removing Vcc, it is highly recommended to put A5100-A into hibernation mode either by ON_OFF pin or soft- ware command. -
Page 17: Antennas
The A5100-A supports passive antennas via an integrated LNA directly. 3.2.2 Active Antennas The A5100-A also supports active antennas directly, i.e. by offering an antenna volt- age feed pin (VANT – pin 9). It is recommended to use an active antenna with a supply voltage of 3 to 5 VDC and a maximum current draw of 50 mA. -

V_BAK at all times so that Navigation data and initial condition (timing and approximate location) are kept current. To reduce power con- sumption, customers can take advantage of the many sophisticated low power mode features available in the SiRFstarV chipset. GPS/GLONASS Receiver Module A5100-A User Guide... -
Page 19: Self-Start Configuration
3: Quick Start 3.5 Self-start Configuration In order to minimize the GPIO required for operating A5100-A, WAKEUP (pin 19) and ON_OFF (pin 6) can be tied together for entering the self-start mode such that no ON_OFF pulse requires. The following picture shows the recommended connection for self-start configuration with UART host port enabled. -
Page 20: Figure 9: Self-Start Configuration A5100-A With Vbak
No power save mode (PTF / MPM / TP) will be supported. Customer can toggle the ON_OFF pin so as to put the module into hibernation and then re- move the Vcc. A5100-A will be self-started again in full power mode when Vcc applied. -

6°C / second max. Time 25°C to peak temperature 8 minutes max. Table 9: Reflow soldering profile A5100-A The solder pads hold solder of a thickness of about 150 µm for improved solder pro- cess results. As results of soldering may vary among different soldering systems and types of sol- der and depend on additional factors like density and types of components on board, the values above should be considered as a starting point for further optimization. -

Vias to GND Layer GPS receiver solder pads Figure 14: Antenna connector strip line A5100-A In order to achieve the impedance of 50 , the width of the strip line needs to be calculated. It depends on the thickness or height of the PCB layer (both parameters are shown in following drawing). - Page 32 In this case, the width should be about 1.8 times the height of the PCB: W = 1.8 x H In the example, one would get a width of W = 1.8 x 0.8 mm = 1.44 mm.

Page 35: Applications And Hints
In order to enter Hibernate Mode it is necessary to send a shutdown command or to toggle to ON_OFF pin by pulling the signal to HIGH for about 200ms. Starting with ROM2.1 the according command is supported in NMEA and SiRF Binary mode. After GPS/GLONASS Receiver Module A5100-A User Guide... - Page 36 The RTC will keep on run- ning and SRAM is backed with the typical current of 20 μA drawn from Vcc. To wake the module up again, toggling the ON_OFF pin is necessary (200ms pulse width). GPS/GLONASS Receiver Module A5100-A User Guide...

Page 37: Battery Back-Up
While the “Super cap” is charged through the module during normal operation, the battery (primary cell) is decoupled thru a diode! Figure 16: Strip line parameters A5100-A An alternative to this solution is to switch the supply voltage from the Vcc pin to the Vbak pin. -
