Product Description

GPS RADIONOVA M10372 is a highly integrated

GPS RF Antenna Module suitable for L1-band GPS

and A-GPS systems. The device is based on the high

performance SiRFstarIV GPS architecture combined

with Antenovas high efciency antenna technology

designed to provide an optimal radiation pattern for

GPS reception.

All RF front-end and baseband components are

contained in a single package laminate base module

providing a complete GPS receiver for optimum

performance. M10372 operates on a single 1.8V

positive bias supply with low power consumption andavailable low power modes for further power savings.

M10372 is a complete GPS system solution with a

stand-alone GPS engine that can generate a PVT

solution without relying upon host-device processing

power and is compatible with UART, SPI and I2C host

processor interfaces.

Custom versions of the M10372 can also incorporate

an antenna switch for optional active antenna

connection. Custom versions are subject to minimum

order quantities.

Recommended Application Schematic for M10372-A1 without

external antenna support

The following schematic shows the recommended connection for the module (without external antenna

support) for stand alone applications. Please contact Antenova for A-GPS applications.

L1-4 and C1,2,3 and 5 are LC lters to prevent in-band GPS noise being conducted into the module. In the event that CTS and RTS are

also connected to the host processor, then similar lters should be used on these lines. Filter components should be placed as close to

the M10372 connector as possible.

A large capacitor should also be included on the VCC line in order to keep the input voltage ripple to a minimum. R1 and R2 are hardware

straps to set the host port conguration on startup.

Recommended Circuit Schematic for M10372-A1X modules to

Support External Antenna

To support an external antenna the module includes an on board RF switch. The host device can control this

switch via the Pin 22 voltage (Vcnt). When this pin is high, the RF switch disconnects the embedded internal

antenna, and routes the signal from pin 28 to the RF front end. In order to provide this control voltage, acurrent detector circuit is suggested. Optional over-voltage protection can also be provided, to protect the

power supply in the event of a short circuit in the antenna connection.

A suggestion for such a circuit is given in the gure below:

U1 and Q1 provide a current sense function, amplifying the voltage drop across sense resistor R1. Thiscurrent sense voltage is used to control the output of the window comparator U2. When the current through

the antenna bias circuit is between 5 and 50mA, then the comparator asserts high, and the RF switch selects

the external antenna. Outside of this range, the comparator detects either a DC short or open circuit in the

bias circuit and asserts low, selecting the internal antenna.

Additionally, the current sense voltage is fed to the gate of Q2, increasing the resistance in the bias circuit as

the voltage rises, and choking off the antenna supply current when it rises above 100mA.

Module Communication - UART

The default UART communication setting for the M10372 is NMEA-0183 protocol at 4800 Baud, 8 data bits, 1

stop bit, no ow control. After boot-up, the host can select a different data rate from 1200 baud up to 1.8432

Mbaud. There is also the option to use hardware ow control.
