The maximum current that can be drained from the ON_OFF* pad is 0,1 mA. A simple circuit to do it is: NOTE: Don't use any pull up resistor on the ON_OFF* line, it is internally pulled up. Using pull up resistor may bring to latch up problems on the UE910 power regulator and improper power on/off of the module. The line ON_OFF* must be connected only in open collector or open drain configuration.

TIP: To check if the device has powered on, the hardware line PWRMON should be monitored. NOTE: It is mandatory to avoid sending data to the serial ports during the first 200ms of the module start-up.

The external power supply must be connected to VBATT & VBATT_PA signals and must fulfil the following requirements: POWER SUPPLY Nominal Supply Voltage Normal Operating Voltage Range Extended Operating Voltage Range 3.8 V 3.40 V÷ 4.20 V 3.10 V÷ 4.50 V NOTE: The Operating Voltage Range MUST never be exceeded; care must be taken when designing the application’s power supply section to avoid having an excessive voltage drop.

Therefore the power supply has to be designed in order to withstand with these current peaks without big voltage drops; this means that both the electrical design and the board layout must be designed for this current flow. If the layout of the PCB is not well designed a strong noise floor is generated on the ground and the supply; this will reflect on all the audio paths producing an audible annoying noise at 216 Hz; if the voltage drop during the peak current absorption is too much, then the device may even shutdown as a consequence of the supply voltage drop. NOTE: The electrical design for the Power supply should be made ensuring it will be capable of a peak current output of at least 2 A. The UE910-EUx variants are supporting EDGE class 33; the NAx variants support EDGE class 10. Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 29 of 79 UE910 Hardware User Guide 1VV0301012 Rev.2 – 24-04-2013 The principal guidelines for the Power Supply Design embrace three different design steps: the electrical design the thermal design the PCB layout. The electrical design of the power supply depends strongly from the power source where this power is drained. We will distinguish them into three categories: +5V input (typically PC internal regulator output) +12V input (typically automotive) Battery The desired output for the power supply is 3.8V, hence there's not a big difference between the input source and the desired output and a linear regulator can be used. A switching power supply will not be suited because of the low drop out requirements. When using a linear regulator, a proper heat sink shall be provided in order to dissipate the power generated. A Bypass low ESR capacitor of adequate capacity must be provided in order to cut the current absorption peaks close to the UE910, a 100μF tantalum capacitor is usually suited. Make sure the low ESR capacitor on the power supply output (usually a tantalum one) is rated at least 10V. A protection diode should be inserted close to the power input, in order to save the UE910 from power polarity inversion. Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 30 of 79 UE910 Hardware User Guide 1VV0301012 Rev.2 – 24-04-2013 An example of linear regulator with 5V input is: The desired output for the power supply is 3.8V, hence due to the big difference between the input source and the desired output, a linear regulator is not suited and shall not be used. A switching power supply will be preferable because of its better efficiency especially with the 2A peak current load represented by the UE910. When using a switching regulator, a 500kHz or more switching frequency regulator is preferable because of its smaller inductor size and its faster transient response. This allows the regulator to respond quickly to the current peaks absorption. In any case the frequency and Switching design selection is related to the application to be developed due to the fact the switching frequency could also generate EMC interferences. For car PB battery the input voltage can rise up to 15,8V and this should be kept in mind when choosing components: all components in the power supply must withstand this voltage. A Bypass low ESR capacitor of adequate capacity must be provided in order to cut the current absorption peaks, a 100μF tantalum capacitor is usually suited. Make sure the low ESR capacitor on the power supply output (usually a tantalum one) is rated at least 10V. For Car applications a spike protection diode should be inserted close to the power input, in order to clean the supply from spikes. A protection diode should be inserted close to the power input, in order to save the UE910 from power polarity inversion. This can be the same diode as for spike protection.

WARNING: The three cells Ni/Cd or Ni/MH 3,6 V Nom. battery types or 4V PB types MUST NOT BE USED DIRECTLY since their maximum voltage can rise over the absolute maximum voltage for the UE910 and damage it. NOTE: DON'T USE any Ni-Cd, Ni-MH, and Pb battery types directly connected with UE910. Their use can lead to overvoltage on the UE910 and damage it. USE ONLY Li-Ion battery types. A Bypass low ESR capacitor of adequate capacity must be provided in order to cut the current absorption peaks, a 100μF tantalum capacitor is usually suited. Make sure the low ESR capacitor (usually a tantalum one) is rated at least 10V. A protection diode should be inserted close to the power input, in order to save the UE910 from power polarity inversion. Otherwise the battery connector should be done in a way to avoid polarity inversions when connecting the battery. The battery capacity must be at least 500mAh in order to withstand the current peaks of 2A; the suggested capacity is from 500mAh to 1000mAh. Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 33 of 79 UE910 Hardware User Guide 1VV0301012 Rev.2 – 24-04-2013 The thermal design for the power supply heat sink should be done with the following specifications: Average current consumption during HSDPA transmission @PWR level max : 800 mA Average current during idle: 1.5 mA NOTE: The average consumption during transmissions depends on the power level at which the device is requested to transmit by the network. The average current consumption hence varies significantly. Considering the very low current during idle, especially if Power Saving function is enabled, it is possible to consider from the thermal point of view that the device absorbs current significantly only during calls. If we assume that the device stays into transmission for short periods of time (let's say few minutes) and then remains for a quite long time in idle (let's say one hour), then the power supply has always the time to cool down between the calls and the heat sink could be smaller than the calculated one for 600mA maximum RMS current, or even could be the simple chip package (no heat sink). Moreover in the average network conditions the device is requested to transmit at a lower power level than the maximum and hence the current consumption will be less than the 600mA, being usually around 150mA. For these reasons the thermal design is rarely a concern and the simple ground plane where the power supply chip is placed can be enough to ensure a good thermal condition and avoid overheating. For the heat generated by the UE910, you can consider it to be during transmission 1W max during CSD/VOICE calls and 2W max during class12 GPRS upload. This generated heat will be mostly conducted to the ground plane under the UE910; you must ensure that your application can dissipate it. Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 34 of 79 UE910 Hardware User Guide 1VV0301012 Rev.2 – 24-04-2013 As seen on the electrical design guidelines the power supply shall have a low ESR capacitor on the output to cut the current peaks and a protection diode on the input to protect the supply from spikes and polarity inversion. The placement of these components is crucial for the correct working of the circuitry. A misplaced component can be useless or can even decrease the power supply performances. The Bypass low ESR capacitor must be placed close to the Telit UE910 power input pads or in the case the power supply is a switching type it can be placed close to the inductor to cut the ripple provided the PCB trace from the capacitor to the UE910 is wide enough to ensure a dropless connection even during the 2A current peaks. The protection diode must be placed close to the input connector where the power source is drained. The PCB traces from the input connector to the power regulator IC must be wide enough to ensure no voltage drops occur when the 2A current peaks are absorbed. Note that this is not made in order to save power loss but especially to avoid the voltage drops on the power line at the current peaks frequency of 216 Hz that will reflect on all the components connected to that supply, introducing the noise floor at the burst base frequency. For this reason while a voltage drop of 300-400 mV may be acceptable from the power loss point of view, the same voltage drop may not be acceptable from the noise point of view. If your application doesn't have audio interface but only uses the data feature of the Telit UE910, then this noise is not so disturbing and power supply layout design can be more forgiving. The PCB traces to the UE910 and the Bypass capacitor must be wide enough to ensure no significant voltage drops occur when the 2A current peaks are absorbed. This is for the same reason as previous point. Try to keep this trace as short as possible. The PCB traces connecting the Switching output to the inductor and the switching diode must be kept as short as possible by placing the inductor and the diode very close to the power switching IC (only for switching power supply). This is done in order to reduce the radiated field (noise) at the switching frequency (100-500 kHz usually). The use of a good common ground plane is suggested. The placement of the power supply on the board should be done in such a way to guarantee that the high current return paths in the ground plane are not overlapped to any noise sensitive circuitry as the microphone amplifier/buffer or earphone amplifier. The power supply input cables should be kept separate from noise sensitive lines such as microphone/earphone cables.

Avoid crossing any un-shielded transmission line footprint with other signal tracks on different layers; The ground surrounding the antenna line on PCB has to be strictly connected to the main Ground Plane by means of via holes (once per 2mm at least), placed close to the ground edges facing line track; Place EM noisy devices as far as possible from UE910 antenna line; Keep the antenna line far away from the UE910 power supply lines; If EM noisy devices are present on the PCB hosting the UE910, such as fast switching ICs, take care of the shielding of the antenna line by burying it inside the layers of PCB and surround it with Ground planes, or shield it with a metal frame cover. If EM noisy devices are not present around the line, the use of geometries like Microstrip or Grounded Coplanar Waveguide has to be preferred, since they typically ensure less attenuation if compared to a Stripline having same length; Install the antenna in a place covered by the GSM signal.

After the release of the line, the UE910 is unconditionally shut down, without doing any detach operation from the network where it is registered.

For this reason the HW_SHUTDOWN* signal must not be used to normally shutting down the device, but only as an emergency exit in the rare case the device remains stuck waiting for some network response. The HW_SHUTDOWN* is internally controlled on start-up to achieve always a proper poweron reset sequence, so there's no need to control this pin on start-up.

This level translator must: invert the electrical signal in both directions; Change the level from 0/1.8V to +15/-15V. Actually, the RS232 UART 16450, 16550, 16650 & 16750 chipsets accept signals with lower levels on the RS232 side (EIA/TIA-562), allowing a lower voltage-multiplying ratio on the level translator. Note that the negative signal voltage must be less than 0V and hence some sort of level translation is always required. The simplest way to translate the levels and invert the signal is by using a single chip level translator. There are a multitude of them, differing in the number of drivers and receivers and in the levels (be sure to get a true RS232 level translator not a RS485 or other standards). By convention the driver is the level translator from the 0-1.8V UART to the RS232 level. The receiver is the translator from the RS232 level to 0-1.8V UART. In order to translate the whole set of control lines of the UART you will need: 5 drivers 3 receivers Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 48 of 79 UE910 Hardware User Guide 1VV0301012 Rev.2 – 24-04-2013 An example of RS232 level adaptation circuitry could be done using a MAXIM transceiver (MAX218) In this case the chipset is capable to translate directly from 1.8V to the RS232 levels (Example done on 4 signals only). The RS232 serial port lines are usually connected to a DB9 connector with the following layout: Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 49 of 79 UE910 Hardware User Guide 1VV0301012 Rev.2 – 24-04-2013 The UE910 is provided by two main interfaces: Analog Audio Path Digital Audio Path The UE910 variants supporting the Audio are listed in the following table:: Product Audio Notes UE910-EUR YES Reserved Pads:,B2, B3, B4, B5 UE910-EUD NO UE910-NAR YES Reserved Pads:,B2, B3, B4, B5 UE910-NAD NO NOTE: The two Paths could not be used in parallel; If the Analog Voice lines are selected, the DVI interface is disabled and Vice versa.

This sounds strange; usually the connection to use in order to reject the common mode is the balanced one. In this situation we have to recall that the microphone is a sound to current transducer, so the resistor is the current to tension transducer, so finally the resistor feeds the input in balanced way even if the configuration, from a microphone point of view, seems to be un-balanced. The following images show some connection examples: Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 51 of 79 UE910 Hardware User Guide 1VV0301012 Rev.2 – 24-04-2013 If a "balanced way" is anyway desired, much more care has to be taken to Vmic noise and ground noise; also the 33pF-100Ohm-33pF RF-filter has to be doubled (one each wire). TIP: Since the J-FET transistor inside the microphone acts as RF-detector-amplifier, ask vendor for a microphone with anti-EMI capacitor (usually a 33pF or a 10pF capacitor placed across the output terminals inside the case). Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 52 of 79 UE910 Hardware User Guide 1VV0301012 Rev.2 – 24-04-2013 If the audio source is not a mike but a different device, the following connections can be done. Place 100nF capacitor in series with both inputs, so the DC current is blocked. Place the 33pF-100Ohm-33pF RF-filter, in order to prevent some EMI field to get into the high impedance high gain MIC inputs. Since the input is differential, the common mode voltage noise between the two (different) ground is rejected, provided that both MIC+ & MIC- are connected directly onto the source.

These outputs can drive directly a small loudspeaker with electrical impedance not lower than 16 Ohm. TIP: in order to get the maximum audio level at a given output voltage level (dBspl/Vrms), the following breaking through procedure can be used. Have the loudspeaker as close as you can to the listener (this simplify also the echo cancelling); choose the loudspeaker with the higher sensitivity (dBspl per W); choose loudspeakers with the impedance close to the limit, in order to feed more power inside the transducer (it increases the W/Vrms ratio). If this were not enough, an external amplifier should be used.
