Environmental requirements 2.7.1. Temperature range   Operating Temperature Range -20 ~ +55°C : This range is defined by 3GPP (the global standard for wireless  mobile  communication).  Telit  guarantees  its  modules  to comply with all the 3GPP requirements and to have full functionality of the module with in this range.  extended temperature -40 ~ +85°C  & commercial temperature 0~+70°C: Telit guarantees full functionality within this range as well. However, there may possibly be some performance deviations in this extended range  relative  to 3GPP  requirements, which  means:    some  RF parameters may deviate from 3GPP specification in the order of few dB.  For example: receiver sensitivity or maximum output power may be slightly degraded.  Even  so,  all  the  functionalities  like data  connection,  SMS ,  USB communication,  UART  activation  etc.  will  be  maintained,  and  the effect of such degradations will not lead to malfunction.   Storage and non-operating Temperature Range  –40°C ~ +105°C

Power supply 5.1. Input supply  There are 2 input power supplies defined on the xE922-3GR module,  V_BAT, V_BAT_PA.  V_BAT_PA pin supplies transmit RF front end (RFFE) power amplifiers (PA) of the cellular network (2G/3G) connection feature of the module.  V_BAT pin supplies the remaining module circuitry, distributed via an internal power management unit (PMU).  Although defined separately, V_BAT and V_BAT_PA can be connected together. The split implementation allows for separate power consumption characterization of the RFFE as well as optional noise filtering network to isolate V_BAT from the typical bursty character of V_BAT_PA in 2G mode operation.    NOTE: In GSM/GPRS mode, RF transmission is not continuous and is packed into bursts at a base frequency of about 216 Hz with relative current peaks as high as about 2 A. Therefore the power supply must be designed to withstand these current peaks (from V_BAT_PA input supply pin) without  big  voltage  drops;  this  means  that  both  the  electrical  design (current rating  and/or decoupling buffer capacitors) 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. This will reflect on all the audio paths producing an audible annoying noise at 216 Hz; if the voltage drops during the peaks, current absorption is too high. The device may even shut down as a consequence of the supply voltage drop.

Page 42 of 112  Both V_BAT_PA and V_BAT are protected by Zener transient voltage suppressor diodes internal the module.

For performance specification of this protection please consult the datasheet.

RTC backup  The internal PMU features real-time clock (RTC) based on 32 kHz oscillator, to keep track of date and time. This feature is supplied by an internal LDO V_RTC, typical 2.3V +-5%. V_RTC is ‘always on’ when V_BAT supply is present (>2.5V min).  V_RTC is internally decoupled with 100 nF. When V_BAT is removed from the module, in case RTC tracking is needed an external supercap is required connected to module pin V_RTC.

An external capacitor for RTC buffering can be added, typical 100uF, up to maximum 220uF directly to the LGA pin V_RTC.  In case an extreme large (super) capacitor, typical 1 F, is applied, a series resistor of typical 470 Ohm should be added. Typical current drawn from V_RTC by the RTC clock: 2.6µA An RTC alarm is one of the possible events to power ON the module.

Power ON/OFF and reset control  6.1. Power On  Once power applied to the V_BAT, the power on can be triggered by four possible events: · ON_OFF key event (+ application of power to system with ‘first connect’ enabled) · External charger detection (CHG_POK) · RTC alarm 6.1.1. ON_OFF key action If the ON_OFF key is forced by external circuitry to V_RTC, the sytem startup procedure begins.  · Active logic : HIGH · T_on minimum : 100msec  · Debounce :15msec   When the system is supplied with V_BAT for the first time, it will automatically start up without waiting for an event.   This so called ‘first connect’ power up condition can be disabled by adding a pulldown resistor on ON_OFF signal of typical 10 kOhm.  Once the system is ON, if the ON_OFF key is forced to V_RTC for minium T_off  > 10 seconds, the system will switch OFF again.  After the initial startup procedure and when FW has booted, the ON_OFF key will be re-programmed to wake up the system when asserted during sleep mode.

Page 50 of 112  6.1.2. Switching ON due to charging If an external charger is detected the system startup procedure begins. An external charger can be detected by LOW level detection on CHG_POK and / or CHG_INT input pins.  Both pins have an internal pullup applied to V_RTC. (See chapter 7.2 for charger IC connections) 6.1.3. Switching on due to RTC alarm The real time clock can generate a wake-up signal called RTC alarm. Once the PMU detects this level high the system startup procedure begins.  6.2. Power off There are two ways to trigger a power off cycle of the system. 6.2.1. Soft power off Based on application specific implementation and/or user interaction, the SW can trigger a power off cycle. 6.2.2. Emergency power off  In case the PMU detects a HW failure, the PMU will shut down by itself. The following events will trigger an emergency power off: · PMU watchdog time-out · ON_OFF key pressed for more than 10 sec · ADC_VBATMEAS < threshold ( default 2.3V) Overtemperature (refer to thermal design guide) 6.3. Reset For soft reset, the system SW can trigger two types of soft reset.  One type will reset the DBB and go through the PMU power off/on sequence,  The other type will only reset the CPU while keeping voltage regulators enabled.  For hard reset, the system can be reset by pulling LGA pin AU5 “MAIN_RESET_IN” active LOW.

USB port The xE922-3GR module includes a Universal Serial Bus (USB) transceiver, which operates at USB high-speed (480Mbits/sec). It can also operate with USB full-speed (12Mbits/sec) hosts. It is compliant with the USB 2.0 ‘DRD’ dual role specification, 15 endpoints, and can be used control and data transfers as well as for diagnostic monitoring and firmware update.  The interface does not support ‘OTG’ (HNP) to switch roles on the fly. Once the module enumerates as a device or host, it stays in that mode. The USB cable needs to be removed and reconnected to enumerate in the alternate mode. The USB port on the Telit xE922-3GR is typically the main interface between the module and OEM hardware.  The USB_D+ and USB_D- signals have a clock rate of 480MHz in HS mode. The signal traces should be  routed carefully. Trace lengths, number of vias  and capacitive loading should be minimized. The impedance value should be as close as possible to 90 Ohms differential. The table below describes the USB interface signals:  For proper DRD operation USB_ID (W17) should be connected to GPIO1_EINT2 (AT18) to detect device connection in low power modes. NOTE:  - VBUS_DET input power is internally used to detect cable VBUS (USB device attach) and start enumeration process. It is not used for supplying internal xE922-3GR USB HW block.

Page 79 of 112  Each SoC pad’s characteristics are controlled by a peripheral called PCL (Port Control Logic). In the next page table a ‘complete’ overview of all PCL muxing options for ‘all DBB pins externally available’ on the xE922-3GR module LGA pinout is detailed out.  In order to clarify the correspondence between the module’s pin naming and chip set supplier documentation naming convention, the DBB SoC BGA ball pin /signal names as well as xE922-3GR LGA pin number / signal names are indicated in different columns.  Yellow color code highlights the xE922-3GR module’s intentional target use. Note:  Please note GPIO2_EINT4 is applicable as “input only” because of internal level shift circuitry to accommodate for 5V VBUS_USB level detect.   Please consult Intel Business Link Support (IBL) for detailed info (like SW user guide) how to program the GPIO configuration/multiplex for your specific application.  Each pad has following characteristics indicated:  Pad pull class: This is the pull-up and pull-down strength of the pad that can be enabled/disabled using PCL registers. There are three pull classes of pads on 1.8V IO domain, A, B, and D (C is not used). A is the strongest (PU=155uA typ, PD=135uA Typ), B is medium (PU=80.8uA typ, PD=64uA typ) and D is the weakest (PU=16.4uA typ, PD=16.2uA typ). Pull-up/pull-down can be enabled through PCL registers but their strength is fixed as indicated in the GPIO spreadsheet, refer to it for each individual pad’s pull class.  Drive strength, also referred to as drive/output current for the pad. 2mA, 4mA, 8mA and 12mA are supported and can be selected by PCL register.  Buffer Type: Schmitt Trigger ST or buffer BU. This setting is not selectable through PCL registers. Refer to GPIO spreadsheet for each individual pad’s buffer type.  RESET state during RESET (PU or PD): All pads come up in a default state during and after reset until PCL registers are initialized. It is important to note that connection of each GPIO to application circuit requires determination whether application circuit is sensitive to the GPIO being HIGH or LOW at reset, e.g., it might not be desirable to have an RF transmitter enabled by default during power-on reset so the GPIO allocated to its RESET and/or power-down input should be such that it holds the transmitter in “disabled” state at the time of power-on until SW takes control. Refer to GPIO table for each individual pad’s default state at reset.  Signal direction during RESET (input or output): Refer to GPIO table for each individual pad’s default direction at reset.  Functions multiplexed on each pad: Each pad not associated with dedicated interfaces can have up to 7 alternate functions multiplexed on it in addition to GPIO function. Refer to GPIO table for each individual pad’s alternate functions. Interrupts: the chip set supports sixteen external interrupts (EINT[15:0]) signals that are multiplexed on different pins but can only be used in one location. Not all interrupt signals are available as some are on pins used for dedicated functions. GPIOs and their different aspects described above can be configured through SW. Please refer to software architecture document for more details.

Loudspeaker ClassD amplifier driving a typical load of 8 ohm. Output stage directly connected to V_BAT, as such max output power depending on V_BAT level, common mode level = V_BAT/2. Switching frequency is about 1.2MHz by default, but can be fine-tuned.  For this frequency and the higher harmonics an external filtering has to be applied which could be inherently done with the connected loudspeaker as well.   Fine tuning allows interference reduction. That means the higher harmonics of the switching frequency can be moved into areas where the interference with other system components is minimized, and on the other side the optimum efficiency for the amplifier can be adjusted. If for example interference between the class-D amplifier switching frequency and the RF-TX carrier is observed, the higher harmonics can be moved to be exactly on the RF-TX carrier frequency. That would hide the class-D amplifier harmonics. For a RF-RX slot the higher harmonics can be moved to a different frequency, so that the RF-RX channel is in the middle between two of the higher harmonic spurs of the class-D amplifier.

Antenna(s) The antenna connection and board layout design are the most important parts in the full product design  and  they  strongly  reflect  on  the  product’s  overall  performance.  Read  carefully  and follow the requirements and the guidelines for a good and proper design. 16.1. GSM/WCDMA Antenna Requirements The antenna for a Telit xE922-3GR device must fulfill the following requirements: When  using  the  Telit  xE922-3GR,  since  there’s  no  antenna  connector  on  the  module,  the antenna must be connected to the  xE922-3GR antenna pad by means of a transmission line implemented on the PCB. In the case that the antenna is not directly connected to the antenna pad of the xE922-3GR, then a PCB line is required in order to connect with it or with its connector. This transmission line shall fulfill the following requirements: Antenna Line on PCB Requirements Characteristic Impedance 50Ohm Max Attenuation 0.3dB Coupling with other signals shall be avoided Cold End (Ground Plane) of antenna shall be equipotential to the xE922-3GR ground pads Furthermore if the device is developed for the US and/or Canada market, it must comply with the FCC and/or IC approval requirements: This device is to be used only for mobile and fixed application. The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. End-Users must be provided with transmitter operation conditions for satisfying RF exposure compliance. OEM  integrators  must ensure  that  the end  user  has  no  manual instructions  to GSM / WCDMA Antenna Requirements Frequency range Depending on the frequency bands provided by the network operator, and of those, which subset of band set the OEM may support while using the Telit module, the customer must use the most suitable antenna for covering those bands.  The bands supported by Telit xE922-3GR module family are given in Section 2.3 Gain Maximum Gain in 1900 MHz band  = 2.5 dBi Maximum Gain in 850 MHz band    = -1.54 dBi Impedance 50 Ohm Input power > 33dBm(2 W) peak power in GSM > 24dBm Average power in WCDMA VSWR absolute max <= 10:1 VSWR recommended <= 2:1

Page 92 of 112  remove or install the xE922-3GR module. Antennas used for this OEM module must not exceed 3dBi gain for mobile and fixed operating configurations.  16.1.1. GSM/WCDMA Antenna – PCB line Guidelines · Make sure that the transmission line’s characteristic impedance is 50ohm. · Keep the line on the PCB as short as possible since the antenna line loss should be less than around 0.3dB. · Line geometry should have uniform characteristics, constant cross section, avoid meanders and abrupt curves. · Any suitable geometry/structure can be used for implementing the printed transmission line affecting the antenna. · If a  Ground  plane is  required in the  line  geometry,  that  plane  must be  continuous  and sufficiently extended so the geometry can be as similar as possible to the related canonical model. · Keep, if possible, at least one layer of the PCB used only for the Ground plane; if possible, use this layer as reference Ground plane for the transmission line. · It is wise to surround (on both sides) the PCB transmission line with Ground. Avoid having other signal traces facing directly the antenna line trace. · Avoid crossing any un-shielded transmission line footprint with other traces on different layers. · The Ground surrounding the antenna line on the PCB must 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 the line trace. · Place EM-noisy devices as far as possible from xE922-3GR antenna line. · Keep the antenna line far away from the xE922-3GR power supply lines. · If EM-noisy devices are present on the PCB hosting the xE922-3GR, such as fast switching ICs, take care to shield them with a metal frame cover. · If EM-noisy devices are not present around the line, using geometries such as Micro strip or Grounded Coplanar Waveguide is preferred since they typically ensure less attenuation compared to a Strip line having the same length.  16.1.2. GSM/WCDMA Antenna – Installation Guidelines · Install the antenna in a location with access to the network radio signal. · If the chosen antenna is a style which requires a ground plane, ensure that it is properly attached, both electrically and mechanically, to a ground plane with dimensions and mechanical structure as recommended by the antenna manufacturer · The antenna must be installed such that it provides a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter; · The antenna must not be installed inside metal cases;

GNSS Antenna Requirements  The GNSS subsystem of xE922-3GR module is visualized on below block diagram.    The module features ‘internal’ pre-LNA_SAW / LNA / post-LNA_SAW   RF chain in front of the GNSS receiver. Two possible GNSS antenna scenarios are possible on the application main board: · Internal ‘passive’ antenna · External ‘active’ antenna Both scenarios are drawn in the figure, only one should be applied.

Page 94 of 112   In case of an internal antenna configuration, it is important to keep the 50 ohm transmission line (TL) short to limit possible signal degradation between antenna and internal LNA amplifier.  In  case  of  an  active  external  antenna,  a  bias  circuit to  feed  the  antenna  integrated  LNA  is required. An inductor filter is used as RF block. Also a DC-block capacitor is required in order to keep unwanted DC voltage away from the internal RF FE devices. Care should be taken to minimize stubs on the 50ohm PCB structure because of placement of these additional bias components. 16.3.1. Combined GNSS Antenna The use of combined RF/GNSS antenna is NOT recommended.  This solution could generate extremely poor GNSS reception. In addition, the combination of antennas requires an additional diplexer, which adds significant power losses in the RF path. 16.3.2. Linear and Patch GNSS Antenna Using linear type of antenna introduces at least 3dB of loss compared to a circularly polarized (CP) antenna. Having a spherical gain response instead of a hemispherical gain response could aggravate the multipath behavior & create poor position accuracy. 16.3.3. Front End Design Considerations When  using  the  Telit  xE922-3GR,  since  there  is  no antenna  connector  on  the  module, the antenna must be connected to the xE922-3GR through the PCB to the antenna pad.  In the case that the antenna is not directly connected at the antenna pad of the xE922-3GR, then a PCB line is required. This line of transmission shall fulfill the following requirements: Antenna Line on PCB Requirements Characteristic Impedance 50Ohm Max Attenuation 0.3dB Coupling with other signals shall be avoided Cold End (Ground Plane) of antenna shall be equipotential to the xE922-3GR  ground pads  Furthermore if the device is developed for the US and/or Canada market, it must comply with the FCC and/or IC requirements. This device is to be used only for mobile and fixed application.

Page 95 of 112  16.3.4. GNSS Antenna - PCB Line Guidelines · Ensure that the antenna line impedance is 50ohm. · Keep the line on the PCB as short as possible to reduce the loss. · The  antenna  line  must  have  uniform  characteristics,  constant  cross  section,  avoiding meanders and abrupt curves. · Keep one layer of the PCB used only for the Ground plane; if possible. · Surround (on the sides, over and under) the antenna line on the PCB with Ground.   Avoid having other signal traces in proximity of the transmission line where coupling may occur. · The Ground around the antenna line on the PCB must be strictly connected to the main Ground plane by placing vias at least once per 2mm. · Place EM-noisy devices as far as possible from xE922-3GR antenna line. · Keep the antenna line far away from the xE922-3GR power supply lines.  · If EM-noisy devices are around the PCB hosting the xE922-3GR, such as fast switching ICs,  ensure  shielding  the  antenna  line  by  burying  it  inside  the  layers  of  PCB  and surrounding it with Ground planes; or shield it with a metal frame cover. · If you do not have EM-noisy devices around the PCB of xE922-3GR, use a Micro strip line on the surface copper layer for the antenna line. The line attenuation will be lower than a buried one. 16.3.5. GNSS Antenna – Installation Guidelines · The xE922-3GR, due to its sensitivity characteristics, is capable of performing a fix inside buildings. (In any case the sensitivity could be affected by the building characteristics i.e. shielding) · If the chosen antenna is a style which requires a ground plane, ensure that it is properly attached,  both  electrically  and  mechanically,  to  a  ground  plane  with  dimensions  and mechanical structure as recommended by the antenna manufacturer · The antenna must not be co-located or operating in conjunction with any other antenna or transmitter. · The antenna shall not be installed inside metal cases.

Recommendations for PCB Pad Dimensions (mm)    It is not recommended to place via or micro-via, which are not covered by solder resist in an area of 0.3 mm around the pads unless it carries the same signal of the pad itself (see following figure).  Holes in pad are allowed only for blind holes and not for through holes. Recommendations for PCB Pad Surfaces: Finish Layer thickness (um) Properties Electro-less Ni / Immersion Au 3 –7 / 0.05 – 0.15 good solder ability protection, high shear force values  The  PCB  must  be  able  to  resist  the  higher  temperatures  which  occur  during  the  lead-free process. This issue should be discussed with the PCB-supplier. Generally, the wettability of tin-lead solder paste on the described surface plating is better compared to lead-free solder paste.
