GE865 Hardware User Guide 1vv0300799 Rev.15– 2012-04-23 6.3. General Design Rules The principal guidelines for the Power Supply Design embrace three different design steps: • the electrical design • the thermal design • the PCB layout. 6.3.1. Electrical Design Guidelines The electrical design of the power supply depends strongly from the power source where this power is drained.
GE865 Hardware User Guide 1vv0300799 Rev.15– 2012-04-23 6.3.1.2. + 12V input Source Power Supply Design Guidelines • • • • • • • • 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 GE865.
GE865 Hardware User Guide 1vv0300799 Rev.15– 2012-04-23 6.3.1.3. Battery Source Power Supply Design Guidelines • The desired nominal output for the power supply is 3.8V and the maximum voltage allowed is 4.2V, hence a single 3.7V Li-Ion cell battery type is suited for supplying the power to the Telit GE865 module. WARNING: The three cells Ni/Cd or Ni/MH 3,6 V Nom.

GE865 Hardware User Guide 1vv0300799 Rev.15– 2012-04-23 9.2. RS232 level translation In order to interface the GE865 with a PC com port or a RS232 (EIA/TIA-232) application a level translator is required. This level translator must: • invert the electrical signal in both directions; • change the level from 0/2.8V to +15/-15V .
GE865 Hardware User Guide 1vv0300799 Rev.15– 2012-04-23 An example of level translation circuitry of this kind is: The example is done with a SIPEX SP3282EB RS232 Transceiver that could accept supply voltages lower than 3V DC. NOTE: In this case Vin has to be set with a value compatible with the logic levels of the module. (Max 2.9V DC). In this configuration the SP3282EB will adhere to EIA/TIA-562 voltage levels instead of RS232 (-5 ~ +5V). Reproduction forbidden without Telit Communications S.p.A.
GE865 Hardware User Guide 1vv0300799 Rev.15– 2012-04-23 Second solution could be done using a MAXIM transceiver (MAX218) In this case the compliance with RS232 (+-5V) is possible. Another level adapting method could be done using a standard RS232 Transceiver (MAX3237EAI) adding some resistors to adapt the levels on the GE865 Input lines. NOTE: In this case has to be taken in account the length of the lines on the application to avoid problems in case of High-speed rates on RS232.
GE865 Hardware User Guide 1vv0300799 Rev.15– 2012-04-23 5V UART level translation If the OEM application uses a microcontroller with a serial port (UART) that works at a voltage different from 2.8 - 3V, then a circuitry has to be provided to adapt the different levels of the two set of signals. As for the RS232 translation there are a multitude of single chip translators.
