1.3.3 SELV Requirements

The power supply connected to the PVS8 module shall be in compliance with the SELV re­quirements defined in EN 60950-1.

1.3.4 Safety Precautions

The following safety precautions must be observed during all phases of the operation, usage,
service or repair of any cellular terminal or mobile incorporating PVS8. Manufacturers of the
cellular terminal are advised to convey the following safety information to users and operating
personnel and to incorporate these guidelines into all manuals supplied with the product. Fail­ure to comply with these precautions violates safety standards of design, manufacture and in­tended use of the product. Cinterion Wireless Modules assumes no liability for customer’s
failure to comply with these precautions.

When in a hospital or other health care facility, observe the restrictions on the use of
mobiles. Switch the cellular terminal or mobile off, if instructed to do so by the guide­lines posted in sensitive areas. Medical equipment may be sensitive to RF energy.

The operation of cardiac pacemakers, other implanted medi cal equipment and hearing
aids can be affected by interference from cellular terminals or mobiles placed close to
the device. If in doubt about potential danger, contact the physician or the manufac­turer of the device to verify that the equipment is properly shielded. Pacemaker
patients are advised to keep their hand-held mobile away from the pacemaker, while
it is on.

Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it can­not be switched on inadvertently. The operation of wireless a ppliances in an aircraft is
forbidden to prevent interference with communications systems. Failure to observe
these instructions may lead to the suspension or denial of cellular services to the
offender, legal action, or both.

Do not operate the cellular terminal or mobile in the presence of flammable gases or
fumes. Switch off the cellular terminal when you are near petrol stations, fuel depo ts,
chemical plants or where blasting operations are in progress. Operation of any electri­cal equipment in potentially explosive atmospheres can constitute a safety hazard.

Your cellular terminal or mobile receives and transmits radio frequency energy while
switched on. Remember that interference can occur if it is used close to TV sets,
radios, computers or inadequately shielded equipment. Follow any special regul ations
and always switch off the cellular terminal or mobile wherever forbidden, or when you
suspect that it may cause interference or danger.

Road safety comes first! Do not use a hand-held cellular terminal or mobile when driv­ing a vehicle, unless it is securely mounted in a holder for speakerphone operation.
Before making a call with a hand-held terminal or mobile, park the vehicle.

Speakerphones must be installed by qualified personnel. Faulty installation or opera­tion can constitute a safety hazard.

IMPORTANT!
Cellular terminals or mobiles operate using radio signals and cellula r networks.
Because of this, connection cannot be guaranteed at all times under all conditions.
Therefore, you should never rely solely upon any wireless device for essential com­munications, for example emergency calls.

Remember, in order to make or receive calls, the cellular terminal or mobile must be
switched on and in a service area with adequate cellular signal strength.

Some networks do not allow for emergency calls if certain network services or phone
features are in use (e.g. lock functions, fixed dialing etc.). You may ne ed to deactivate
those features before you can make an emergency call.

Bear in mind that exposure to excessive levels of noise can cause physical damage
to users! With regard to acoustic shock, the cellular application must be designed to
avoid unintentional increase of amplification, e.g. for a highly sensitive earpiece. A pro­tection circuit should be implemented in the cellular application.

3.2 Power Supply

PVS8 needs to be connected to a power supply at the SMT application interface - 6 lines each
BATT+ and GND. There are three separate voltage domains for BATT+:

• BATT+_PA1 with 2 lines for the first power amplifier supply

• BATT+_PA2 with 2 lines for the second power amplifier supply

• BATT+ with 2 lines for the general power management.
The main power supply from an external application has to be a single voltage source and has

to be expanded to three sub paths (star structure). Capacitors should be placed as close as
possible to the BATT+ pads. Figure 2 shows two sample circuits (minimum requirement and
recommended alternative) for decoupling capacitors for BATT+.

Figure 2: Decoupling capacitor(s) for BATT+

The power supply of PVS8 must be able to provide the peak current during the uplink transmis­sion.

All key functions for supplying power to the device are handled by the power management IC.
It provides the following features:

• Stabilizes the supply voltages for the baseband using switching regulators and low drop lin-
ear voltage regulators.

• Switches the module's power voltages for the power-up and -down procedures.

• Delivers, across the VEXT line, a regulated voltage for an external application. This voltage
is not available in Power-down mode and can be reduced via AT command to save power.

3.3 USB Interface

PVS8 supports a USB 2.0 High Speed (480Mbit/s) device interface that is Full Speed (12Mbit/s)
compliant. The USB interface is primarily intended for use as command and data interface and
for downloading firmware.

The external application is responsible for supplying the VUSB_IN line. This line is used for ca­ble detection only. The USB part (driver and transceiver) is supplied by means of BATT+. This
is because PVS8 is designed as a self-powered device compliant with the “Universal Serial Bus
Specification Revision 2.0”

1

.

Figure 3: USB circuit

To properly connect the module's USB interface to the external application, a USB 2.0 compat­ible connector and cable or hardware design is required.

3.4 Serial Interface ASC0

PVS8 offers an 8-wire unbalanced, asynchronous modem interface ASC0 conforming to ITU­T V.24 protocol DCE signalling. The electrical characteristics do not comply with ITU-T V.28.
The significant levels are 0V (for low data bit or active state) and 1.8V (for high data bit or in­active state).

PVS8 is designed for use as a DCE. Based on the conventions for DCE-DTE connections it
communicates with the customer application (DTE) using the following signals:

• Port TXD @ application sends data to the module’s TXD0 signal line

• Port RXD @ application receives data from the module’s RXD0 signal line

Figure 4: Serial interface ASC0

Features:

• Includes the data lines TXD0 and RXD0, the status lines RTS0 and CTS0 and, in addition ,
the modem control lines DTR0, DSR0, DCD0 and RING0.

• ASC0 is designed for controlling voice calls, transferring data and for controlling the module
with AT commands.

• Full multiplexing capability allows the interface to be partitioned into virtual channels.

• The RING0 signal serves to indicate incoming calls and other types of URCs (Unsolicited
Result Code). It can also be used to send pulses to the host application, for example to
wake up the application from power saving state. See [1] for details on how to config ure the
RING0 line by AT^SCFG.

• Configured for 8 data bits, no parity and 1 stop bit.

• ASC0 can be operated at fixed bit rates from 9600bps up to 921600bps.

• Supports RTS0/CTS0 hardware flow control.

• Wake up from SLEEP mode by RTS0 activation (high to low transition).

Note. If the ASC0 serial interface is the application’s only interface, it is suggested to connect
test points on the USB signal lines as a potential tracing possibility.

3.5 Analog Audio Interface

PVS8 has an analog audio interface with a balanced analog microphone input and a balanced
analog earpiece output. A supply voltage and an analog ground connection are provided at
dedicated lines.

PVS8 offers eight audio modes which can be selected with the AT^SNFS command. The elec­trical characteristics of the voiceband part vary with the audio mode. For example, sending and
receiving amplification, sidetone paths, noise suppression etc. depend on the selected mode
and can in parts be altered with AT commands (except for mode 1).

When shipped from factory, all audio parameters of PVS8 are set to audio mode 1. This is the
default configuration optimised for the Votronic HH-SI-30.3/V1.1/0 handset and used for type
approving the Cinterion Wireless Modules reference configuration. Audio mode 1 has fix pa­rameters which cannot be modified. To adjust the settings of the Votronic handset simply
change to another audio mode.

3.6 Digital Audio Interface

PVS8 supports a digital audio interface that can be employed either as pulse code modulation
or as inter IC sound interface. Operation of these interface variants is mutually exclusive.

4 GNSS Receiver

PVS8 integrates a GNSS receiver that offers the full performance of GPS/GLONASS technol­ogy. The GNSS receiver is able to continuously track all satellites in view, thus providing accu­rate satellite position data.

The integrated GNSS receiver supports the NMEA protocol via USB or ASC0 interface

1

. NMEA
is a combined electrical and data specification for communication between various (marine)
electronic devices including GNSS receivers. It has been defined and controlled by the US­based National Marine Electronics Association. For more information on the NMEA Standard
please refer to http://www.nmea.org.

Depending on the receiver’s knowledge of last position, current time and ephemeris data, the
receiver’s startup time (i.e., TTFF = Time-To-First-Fix) may vary: If the receiver has no knowl­edge of its last position or time, a startup takes considerably longer than if the receiver has still
knowledge of its last position, time and almanac or has still access to valid ephimeris data and
the precise time.

By default, the GNSS receiver is switched off. It has to be switched on and configured using
AT commands. For more information on how to control the GNSS interface via the AT com­mand AT^SGPSC see [1].

1.

Using the serial ASC0 interface NMEA data is transmitted at a fixed speed of 115200bps.

5 Antenna Interfaces

5.1 CDMA Antenna Interface

The PVS8 CDMA antenna interface comprises a main CDMA antenna as well as an optional
CDMA Rx diversity antenna to improve signal reliability and quality

1

. The interface has an im-

pedance of 50

. PVS8 is capable of sustaining a total mismatch at the antenna interface wit h-

out any damage, even when transmitting at maximum RF power.
The external antenna must be matched properly to achieve best performance regarding radi-

ated power, modulation accuracy and harmonic suppression. Matching networks are not in­cluded on the PVS8 PCB and should be placed in the host application, if the antenna does not
have an impedance of 50

.

Regarding the return loss PVS8 provides the following values in the active band:

1.

By delivery default the optional CDMA Rx diversity antenna is configured as available for the module. To
avoid negative side effects and performance degradation it is recommended to disable the diversity an­tenna path if

- the host application does not support a diversity antenna

- the host application includes a diversity antenna - but a network simulator is used for development and
performance tests.
Please refer to [1] for details on how to configure antenna settings.

5.1.1 Antenna Installation

The antenna is connected by soldering the antenna pads and their neighboring ground pads
directly to the application’s PCB.

The distance between the antenna pads and their neighboring GND pads has been optimized
for best possible impedance. To prevent mismatch, special attention should be paid to these
pads on the application’ PCB.

The wiring of the antenna connection, starting from the antenna pad to the application’s anten­na should result in a 50

 line impedance. Line width and distance to the GND plane need to

be optimized with regard to the PCB’s layer stack.
To prevent receiver desensitization due to interferences generated by fast transients like high

speed clocks on the external application PCB, it is recommended to realize the antenna con­nection line using embedded Stripline rather than Micro-Stripline technology.

For type approval purposes, the use of a 50

 coaxial antenna connector (U.FL-R-SMT) might

be necessary. In this case the U.FL-R-SMT connector should be placed as close as possible
to PVS8‘s antenna pad.

5.2 GNSS Antenna Interface

In addition to the RF antenna interface PVS8 also has a GNSS antenna interface. The GNSS
antenna installation and connector are the same as for the RF antenna interface (see Section

5.1.1). For use with GPS and GLONASS it is recommended to use a GPS and GLONASS ca-

pable antenna.
It is possible to connect active or passive GNSS antennas. In either case they must have 50

Ohm impedance. The simultaneous operation of CDMA and GNSS has been implemented.
PVS8 provides the supply voltage VGNSS for the GNSS active antenna (3.05V). It has to be

enabled by software when the GNSS receiver shall becomes active, otherwise VGNSS should
be off (power saving). VGNSS is not short circuit protected. This will have to be provided for by
an external application. The DC voltage should be fed back via ANT_GNSS_DC for coupling
into the GNSS antenna path. Figure 5 shows the flexibility in realizing the power supply for an
active GNSS antenna by giving two sample circuits realizing the supply voltage for an active
GNSS antenna - one with short circuit protection and one with an external LDO employed.

7 Sample Application

Figure 9 shows a typical example of how to integrate an PVS8 module with an application.

The audio interface demonstrates the balanced connection of microphone and earpiece. This
solution is particularly well suited for internal transducers.

The PWR_IND line is an open collector that needs an external pull-up resistor which connects
to the voltage supply VCC µC of the microcontroller. Low state of the open collector pulls the
PWR_IND signal low and indicates that the PVS8 module is active, high level notifies the Pow­er-down mode.

If the module is in Power-down mode avoid current flowing from any other source into the mod­ule circuit, for example reverse current from high state external control lines. Therefore, the
controlling application must be designed to prevent reverse flow. If an external level controller
is required, this can be done by using for example a 5V I/O tolerant buffer/driver like a
"74AVC4T245" with OE

(Output Enable) controlled by PWR_IND.

While developing SMT applications it is strongly recommended to provide test points
for certain signals resp. lines to and from the module - for debug and/or test purposes.
The SMT application should allow for an easy access to these signals. For details on
how to implement test points see [4].

The EMC measures are best practice recommendations. In fact, an adequate EMC strategy for
an individual application is very much determined by the overall layout and, especially, the po­sition of components.

Disclaimer:
No warranty, either stated or implied, is provided on the sample schematic diagram shown in

Figure 9 and the information detailed in this section. As functionality and compliance with na-

tional regulations depend to a great amount on the used electronic components and the indi­vidual application layout manufacturers are required to ensure adequate design and operating
safeguards for their products using PVS8 modules.

8 Reference Approval

8.1 Reference Equipment for Type Approval

The Cinterion Wireless Modules reference setup submitted to type approve PVS8 is shown in

Figure 10. The module (i.e., the evaluation module) is connected to the DSB75 by means of a

flex cable and a special DSB75 adapter. The CDMA/GNSS test equipment is connected via
edge mount SMA connectors soldered to the module’s antenna pads.

For ESD tests and evaluation purposes, it is also possible connect the module to the CDMA/
GNSS test equipment through an SMA-to-Hirose-U.FL antenna cable and the SMA antenna
connectors of the DSB75 adapter.

A further option is to mount the evaluation module directly onto the DSB75 adapter’s 80-pin
board-to-board connector and to connect the test equipment as shown below.
