PAGE 26
Product Technical Specification & Customer Design Guidelines 3.1.1 Burst transmission current requirements The power supply must be able to deliver high current peaks in a short time due to the burst transmission nature of GSM. During these peaks, the ripple (Uripp) on the supply voltage must not exceed the level noted in Table 3-1 on page 25. Table 3-3 describes radio burst rates in connected mode. For detailed power consumption figures, see Table 6-2 on page 77.

3.2 Ground connection The AirPrime SL808X Embedded Module shielding case is the grounding. The ground must be connected on the motherboard through a complete layer on the PCB. The ground connection is made by soldering the LGA ground pins and rectangular ground pad to the ground plane of the application board. For more information about ground connection, see Ground plane and shielding connection on page 97. 3.

Product Technical Specification & Customer Design Guidelines 5.2 Power on/off signal (POWER_ON_N) This signal is used to switch the AirPrime SL808X Embedded Module ON or OFF. Table 5-2: Power signal features Feature Details Purpose Power on/off • Simulates a power button. Implementation • Low = On • Digital input • Line should be driven only by an open-drain output from the host • Level is internally pulled up to 2.6 V 5.2.1 Pin descriptions Table 5-3 describes the POWER_ON_N signal pins.

2. Wait at least 50 ms, then assert POWER_ON_N (active low) for at least 400 ms to turn on the module. 3. Release the POWER_ON_N signal (module has internal pull-up to 2.6 V). Module is now in the ‘on’ (normal) power state. To power off the modem, the host must: 1. Drive the signal low for at least 500 ms in order to initiate the power-down sequence, and then release it. (The modem continually monitors POWER_ON_N.) The module should now be in the ‘off’ power state. Rev 1 Dec.

8 8: Design Guidelines This chapter provides general design guidelines for the AirPrime SL808X Embedded Module. Caution: This chapter is under development—all recommendations must be considered as ‘TBD’. For industrial assembly guidelines, refer to [7] Customer Process Guidelines—AirPrime SL Series, available from your Sierra Wireless account representative. 8.1 General rules and constraints Clock and other high frequency digital signals (e.g.
PAGE 96
Product Technical Specification & Customer Design Guidelines • The capacity to deliver high current peaks in a short time (pulsed radio emission). • The VCC_3V6 line must support peak currents with an acceptable voltage drop which guarantees a minimal VCC_3V6 value of 3.3 V (lower limit of VCC_3V6) 8.4 Antenna Another key issue in the design of a GSM terminal is the mechanical and electrical antenna adaptation.
PAGE 97
8.7 Routing constraints 8.7.1 Power supply Since the maximum peak current can reach 2 A, Sierra Wireless strongly recommends having a large width for the layout of the power supply signal (to avoid voltage loss between the external power supply and the AirPrime SL808X Embedded Module supply). Pins 42 and 44 of the AirPrime SL808X Embedded Module should be gathered in the same piece of copper, as shown in the figure below.
PAGE 98
Product Technical Specification & Customer Design Guidelines A ground plane must be available on the application board to provide efficient connection to the bottom ground of the AirPrime SL808X Embedded Module. The bottom side shielding of the AirPrime SL808X Embedded Module is achieved by soldering the ground plane of the application board and the AirPrime SL808X Embedded Module. The best shielding performance is achieved when the application ground plane is a complete layer of the application PCB.
PAGE 99
Figure 8-3: AppCad screenshot for MicroStrip design If a multi-layered PCB is used, the RF path on the board must not cross any signal (digital, analog or supply). If necessary, use StripLine structure and route the digital line(s) "outside" the RF structure as shown in the figure below. 50 line LGA pin for ANT Figure 8-4: Routing examples Stripline and Coplanar design requires having a correct ground plane at both sides. Consequently, it is necessary to add some vias along the RF path.

Product Technical Specification & Customer Design Guidelines The GSM/GPRS connector is intended to be directly connected to a 50  antenna and no matching is needed. 8.8 EMC and ESD recommendations EMC tests have to be performed on the application as soon as possible to detect any potential problems.
PAGE 101
8.9 Mechanical integration Attention should be paid to: • Antenna cable integration (bending, length, position, etc) • Leads of the AirPrime SL808X Embedded Module to be soldered to the ground plane 8.10 Operating system upgrade The AirPrime SL808X Embedded Module Operating System is stored in flash memory and can be easily upgraded.

Product Technical Specification & Customer Design Guidelines 9.4 Module testing recommendations When testing your integration design: • Test to your worst case operating environment conditions (temperature and voltage) • Test using worst case operation (transmitter on 100% duty cycle, maximum power) • Monitor temperature at the location shown below—this should be the hottest spot on the device (the WCDMA PA).

Figure 9-2: Main serial link (UART1) debug access When it is necessary to download firmware into the AirPrime SL808X Embedded Module without going through the RS232 interface, access to the embedded module is forced via the debug connector. An economical solution consists of making the debug connection using 7 test points (TP) and placing these points on the edge of the application board. 9.

12 12: Safety Recommendations (For Information Only) For the efficient and safe operation of your GSM application based on the AirPrime SL808X Embedded Module, please read the following information carefully. 12.1 RF safety 12.1.1 General Your GSM terminal is based on the GSM standard for cellular technology. The GSM standard is spread all over the world. It covers Europe, Asia and some parts of America and Africa. This is the most used telecommunication standard.
PAGE 114
Product Technical Specification & Customer Design Guidelines Do not hold the antenna when the terminal is "IN USE". Holding the antenna affects call quality and may cause the modem to operate at a higher power level than needed. 12.1.4 Antenna care and replacement Do not use the GSM terminal with a damaged antenna. If a damaged antenna comes into contact with the skin, a minor burn may result. Replace a damaged antenna immediately.
PAGE 115
12.2.5 Aircraft Turn your terminal OFF before boarding any aircraft. • Use it on the ground only with crew permission. • Do not use it in the air. To prevent possible interference with aircraft systems, Federal Aviation Administration (FAA) regulations require you should have prior permission from a crew member to use your terminal while the aircraft is on the ground. To prevent interference with cellular systems, local RF regulations prohibit using your modem while airborne. 12.2.
