Host Interface Overview
UART Interface
The default UART communication setting for the M10478 is NMEA-0183 protocol at 4800 Baud, 8 data bits, 1
stop bit, no ow control.
• TX: Output from the GSD4e
• RX: Input to the GSD4e
• RTS (optional): hardware ow control, high when ready to transmit
• CTS (optional): hardware ow control input, high when host allows transmission
While RX and CTS inputs are 3.3V compatible, if RX is driven from a source higher than 1.8V, current may
ow from the driver in reverse through the GSD4e’s ~80kΩ internal pull-up resistor. TX has maximum 1.8 V
logic high output level and may require an external level shifter to interface with a 3.3V input on a host.
UART Interface Logic Levels
Symbol Description Min Max Unit
VIL Low Level Input Voltage -0.4 0.45 V
VIH High Level Input Voltage 0.7 x VCC 3.6 V
VOL Low Level Output Voltage - 0.4 V
VOH High Level Output Voltage 0.75 x VCC - V
Conguration 1:
• RX and TX data lines only, no hardware or software ow control
Conguration 2:
• RX and TX lines for data transmissions
• RTS and CTS for hardware ow control under standard hardware ow control principles
• Transmission stops at the end of the current character and restarts when CTS goes high.
GSD4e may lose or garble serial messages if host ow control throttling is too severe. GSD4e design expects
unrestricted outow of serial messages.
The UART interface can be run at baud rates from 1200 to 1.8432 MBaud. The default protocol is determined
by hardware conguration (see Hardware Baud Rate Selection Table above).

Host SPI Interface (Slave)
The host interface SPI is a slave mode SPI.
The 4 SPI pins are:
• Pin 13: slave SPI data output (MISO)
• Pin 12: slave SPI data input (MOSI)
• Pin 14: slave SPI clock input (CLK)
• Piin 16: slave SPI chip select (CS#) active low
The maximum clock frequency supported is 6.8MHz.
To allow the module to awaken or signal the host that messages are ready within the GSD4e, the GSD4e
software can be programmed or congured to generate a “Message Waiting” signal on a pre-assigned GPIO.
While the Host SPI serial Input and Host SPI clock Input are 3.3V compatible, if Host SPI serial Input is driven
from a source higher than 1.8V, excess leakage current may ow through the ~80kΩ internal pull-up resistor.
Host SPI serial Output has maximum 1.8V logic high output level and may require an external level shifter to
interface with a 3.3V input.
The following internal operation details are provided to assist with implentation troubleshooting:
• TX and RX each have independent 1024 byte FIFO buffers
• RX and TX each have independent software-specied two byte idle patterns
• TX FIFO is disabled when empty and transmits its idle pattern until re-enabled
• RX FIFO detects a software specic number of idle pattern repeats and then disables FIFO input until
the idle pattern is broken
• FIFO buffers can generate an interrupt at any ll level
• SPI detects synchronization errors and can be reset by software.

Host I2C Interface
The GSD4e supports two-wire I2C operation in multi-master mode only, with behavior comparable to UART
mode operation.
• Address format is 7-bit (default) or 10-bit. I2C supports multiple masters and multiple slaves. The
GSD4e address as master (when sending) is 0x62 and as slave (when receiving) is 0x60
• Current I2C Data rates: bit clock rates are 400 kbps (default – fast mode) and 100 kbps (standard
mode). High speed mode is not supported. Data rate can be changed using OSP message ID 178
• Internal FIFOs for RX and TX are 64 bytes.
For proper operation, external pull-ups are required to ensure proper rise times with stray shunt capacitances
from attached loads and traces.
SPI and I2C Interface (Master Mode)
The M10478 provides an auxiliary serial interface that can be congured as either a master I²C interface or a
master SPI bus. These features are implemented using either 2 or 4 of the GPIO pins on M10478. Only one
of these buses may be implemented on a receiver.
At start-up, the receiver automatically detects either an I²C EEPROM or a SPI serial ash memory and sets
itself appropriately. If GSD4e WLCSP does not detect memory of either type, the system is congured for an
I²C bus for sensor interface.
Master I2C Interface
This mode is the default for the receiver. It can be used to communicate with MEMS sensors such as
accelerometers, Magneto-meters and altimeters, and with EEPROM storage devices. Some features of the
interface include:
• Support for most common sensor formats (accelerometers, gyros, magnetometers, altimeters)
• Support for multiple data lengths
• Standard I2C bus data rates of 100kbps and 400kbps
• Accepts both 64KB and 128KB EEPROMS
• 128KB EEPROMs can store server-generated EE les up to 7 days in length
Master SPI Interface
Non-volatile memory storage can be provided by either 2Mbit or 4Mbit serial ash memories from either
SST or EON. The ash memory can store a ROM patch, both server-generated and client-generated
extended ephemeris les (up to 31 days in length if 4MB or greater), satellite almanacs, crystal temperature
characterization data and data logs. All of these items can be stored simultaneously on the same ash device.
Through the master SPI interface, GSD4e WLCSP reads and writes data at approximately 1.0Mbps, with a
maximum of 1.25Mbps

Power Management
Full Power ON mode
In the FULL ON state, the ARM processor in the GSD4e is enabled and clocked and the system is under
software control. This is the operating state during all acquisition and tracking modes. All RF/BB domains are
powered and clocked. However, the software has control of clocks and bias currents, it removes the clocks
and bias currents from digital and RF/analog circuits when these circuits are not in use.
Hibernate
In Hibernate state, only essential areas are powered, RTC, IO, RAMs. Current levels are typically 20μA.
At start-up, the module requires an ON_OFF pulse sent from the host. A second pulse sent from the host will
re-enter hibernate mode. The ON_OFF pulse needs to be the rising edge of a low to high pulse, this needs to
be longer than 90us.
If the host device does not require the hardware selection of hibernate mode, the wakeup pin can be
connected to the ON_OFF pin to automatically wake the module to a full power state.
Trickle Power (TP)
Trickle power enters a duty cycle mode to reduce the average current consumption, but still retaining a high
standard of accuracy and performance from the module. This means being able to still track weak signals
Typically under normal conditions TP mode runs in full power for 100-900ms and provides a x, followed by a
1-10 second interval of a low power standby state. Once in a while (typically every 1800 seconds) the module
will return to Full power mode to update the ephemeris data.
When in TP, if the signal conditions are harsh (below 30dB-Hz) the module will automatically switch to Full
Power mode to improve the navigation performance. When conditions return to normal, the module will
return to TP mode. This results in variable power savings but for a xed output rate, much more reliable
performance. Applications using TP Mode perform similarly to applications using full power, but with
signicant power savings in strong-signal conditions.
Push to Fix (PTF)
Push to x is similar to TP except:
• The time in the OFF state is longer
• It uses the hibernate settings
• It has a typical duty-cycle of about 2 hours
• It is prepared to wake any time in response to an edge on the ON_OFF pin
PTF Mode is for applications that require infrequent position reporting. The GPS generally stays in a low-
power mode, up to 2 hours. Upon wake-up, GPS data is checked for aging validity versus the position update
rate to determine if a refresh of position, time, ephemeris data and RTC calibration is required before the next
Hibernate cycle. The PTF Mode puts the receiver into a background duty-cycle mode that provides a periodic
refresh of position, GPS time, ephemeris and RTC calibration every 10 seconds to 2 hours.

GPS RADIONOVA® RF Antenna Module
Part No. M10478
By default, the PTF Mode period is 30 minutes. It is programmable between 10 seconds and 2 hours. When
the PTF Mode is enabled at power on or a new PTF Mode cycle, the receiver stays on FP Mode until a good
navigation solution is computed. The Hibernate state follows for the remainder of the period. If it takes 36
seconds to x position and refresh ephemeris on the default period of 30 minutes, the GPS sleeps for the 29
minutes and 24 seconds.
Upon wakeup, the module will remain in full power mode until a good navigation solution is found.
Micro Power Mode (MPM)
MP Mode is a very low-power maintenance mode. The objective of MP Mode is to remain below a stated
average current level while maintaining a low level of uncertainty in time, frequency, position and ephemeris
state.
MP Mode operates by capturing a buffer of GPS samples at infrequent intervals and analysing the data
to update its time, frequency and position estimates. For satellites needing updated ephemeris data, a
data collection is scheduled when strong signals are detected. During the data collection phase, time and
frequency calibration operations are also carried out.
When switched on the module updates in cycles, usually 1-10 minutes, or maintenance cycles of 30–60
minutes.
Typical Capture/Update frequency varies: about once every ten minutes for 9 seconds. Data collection is
twice an hour at ~18 seconds each.
Please contact Antenova for more information for MPM and all other low power states.
SiRF Instant Fix (AGPS)
There are two methods to acquire extended ephemeris data:
• SGEE (Requires network connections)
• CGEE (Module Generated - no network connection needed)
SGEE (Server Generated Extended Ephemeris)
SGEE requires periodically accessing servers to download an extended ephemeris (EE) le and transfer it to
GSD4e. GSD4e can store EE data to serial EEPROM, ash or host.
CGEE (Client Generated Extended Ephemeris)
The M10478 supports CGEE (Client Generated Extended Ephemeris). CGEE functionality enables devices
without an Internet connection to generate EE information based on BE collected from satellites during normal
use. This means the module will collect data automatically to generate a predicted ephemeris le, which
can dramatically reduce TTTF. The CGEE is default ON, but only if the module has an external serial ash
connected to the SPI bus to be able to store the data. Up to 31 days of predicted data can be stored.
Please contact Antenova for more information on SGEE and CGEE

External Matching
The M10478 module uses a matching circuit on the host PCB in order to ne-tune the on-board antenna
to each specic application. This “external matching” allows compensating for the detuning of the antenna
caused by various different components that can be close to the M10382 module in the actual application
(plastic case, battery, speakers etc).
The external matching must be placed on the host PCB between ANT_OUT (PIN3) and ANT_IN (PIN1).
Although 2 components are typically more than enough to match the antenna to the 50Ω impedance required,
a P-network topology with 3 components is recommended for safe proving.
Schematic
Both low-pass and hi-pass topologies for the matching network can be used with similar results. As the
same footprint can be used for both topologies, the exact type and value of the components used can be
determined during the optimization phase.
• The initial values can be simply chosen as the null-circuit (no impedance matching):
• Hi-pass:
• C1 = 18pF
• L1, L2 = Not Fitted
• Low-pass:
• L1 = Jumper (0Ω resistor)
• C1, C2 = Not Fitted

Type of Matching Components
• Capacitors:
• Use 0402, COG components
• Inductors:
• High-Q, wire wound inductors in 0402 size are recommended for maximum performance,
e.g. Murata LQW15 series
• Good quality multi-layer type inductors (e.g. Murata LQG15 series) can also be used as a
lower cost alternative
Matching Procedure
The types and values of the matching components must be chosen so that the impedance seen by port
ANT_IN (PIN4) is as close as possible as 50Ω. Although it is a relatively simple operation, it requires some
RF skills and a VNA (Vector Network Analyzer). Please contact an Antenova M2M FAE to get support on
dening the optimal matching for your specic device.
External Antenna Support
A low cost external circuit can be used to provide external antenna support. Please contact Antenova for more
information, and example circuit.
PCB Matching Circuit Layout
The layout of the external matching circuit should be done using the following guidlines:
• Minimize the length of the tracks connecting the ANT_OUT and ANT_IN pads to the matching
• Minimize the length of the tracks between the components
• Use a solid groundplane under the matching circuit area
• Absolutely avoid routing any track under the matching circuit area
• Connect the top ground layer with the ground layer underneath using several vias
Layout drawings (Gerber or other format) are available from Antenova. Please contact your local FAE.

Internal Antenna Clearance
The M10478 module internal antenna requires a small clearance on the host PCB to operate. The clearance
means that no Ground or tracks of any kind are allowed to be within this area. This must also be clear through
the entire PCB stack up. The minimum area needed clear is 6mm X 4.87mm.

GPS RADIONOVA® RF Antenna Module
Part No. M10478
Module Placement Guidelines
Due to the internal antenna, care must be taken when dening the placement of the module on the host PCB.
Here are some guidelines that should be used when deciding the position of the module.
• The module top edge must be placed almost level with the edge of the host PCB
• The edge of the host PCB that the module is to be placed at must be a minimum of 40mm in length.
• The central placement of the module is advised. However, an offset placement is also possible.
• For an offset closer to the PCB edge to the right side of the module, a minimum of 10mm distance is
required to the edge of the host PCB.
• For an offset closer to the PCB edge on the left side of the module, a minimum of 15mm distance is
required to the edge of the host PCB. This additional distance is due to the matching circuit placement.

• For an offset closer to the PCB edge to the left side of the module, a minimum of 15mm distance is
required to the edge of the host PCB. This additional distance is due to the matching circuit placement.
• The antenna uses the host PCB ground to effectively radiate. As such, a GND plane must be placed
on the host PCB on at least one layer.
• In the example below, the only area void of GND is the antenna keep-out area.

• An ideal stack-up for a host PCB would be to use the top and bottom layers as GND planes, while
using the internal layers for any signal and power planes. This not only helps the GPS antenna to
perform effectively, but also helps to reduce any potential noise issues that can be associated with
mixed signal PCB’s.
• An exaggerated example below shows a 4 layer host PCB, GND ooding all available space not used
by signals or components.
Please contact Antenova M2M for advice on placement.

Reow Soldering
Placement
Typical placement systems used for any BGA/LGA package are acceptable. Recommended nozzle diameter
for placement: 5mm
Soldering Paste
Use of “No Clean” soldering paste is strongly recommended, as it does not require cleaning after the
soldering process has taken place. An example of suitable soldering paste is Alpha OM350.
Soldering
The recommended soldering prole for M10478 is shown below. However, it is the responsibility of the
Contract Manufacturer to determine the exact reow prole used, taking into consideration the parameters of
the host PCB, solder paste used, etc.
Prole Feature Pb-Free Solder

Peak Package Body Temperature (Tp)245°C
Time within 5°C of peak temp (tp)30s
Average Ramp up rate - Ts(max) to (Tp)3°C/s
Ramp Down Rate 6°C/s max
Example Reow prole
The Pb Free Process-Package Peak Reow Temperature is 260ºC.
Exceeding the maximum soldering temperature could permanently damage the module.

Multiple Soldering
The M10478 module can be submitted up to 2 reow soldering processes.
Upside-down soldering is acceptable but it is recommended that the Contract Manufacturer qualify the
process before mass production. The second reow must take place within the recommended oor life limit
(MSL3). Please contact Antenova for further information.
Hand Soldering
Hand-soldering and rework of the M10478 module is acceptable, however care must be taken to avoid short
circuits due to the small size of the module pads.
