GE865 Hardware User Guide 1vv0300799 Rev.11 – 13-07-2010 6 Power Supply The power supply circuitry and board layout are a very important part in the full product design and they strongly reflect on the product overall performances, hence read carefully the requirements and the guidelines that will follow for a proper design. 6.

GE865 Hardware User Guide 1vv0300799 Rev.11 – 13-07-2010 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.11 – 13-07-2010 An example of linear regulator with 5V input is: 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.11 – 13-07-2010 A protection diode should be inserted close to the power input, in order to save the GE865 from power polarity inversion. This can be the same diode as for spike protection. An example of switching regulator with 12V input is in the below schematic (split in 2 parts): Reproduction forbidden without Telit Communications S.p.A.
GE865 Hardware User Guide 1vv0300799 Rev.11 – 13-07-2010 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.

GE865 Hardware User Guide 1vv0300799 Rev.11 – 13-07-2010 6.3.3 Power Supply PCB layout Guidelines 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.
GE865 Hardware User Guide 1vv0300799 Rev.11 – 13-07-2010 7 Antenna The antenna connection and board layout design are the most important aspect in the full product design as they strongly affect the product overall performances, hence read carefully and follow the requirements and the guidelines for a proper design. 7.

GE865 Hardware User Guide 1vv0300799 Rev.11 – 13-07-2010 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.11 – 13-07-2010 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.11 – 13-07-2010 9.3 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.
GE865 Hardware User Guide 1vv0300799 Rev.11 – 13-07-2010 NOTE: The input lines working at 2.8VCMOS can be pulled-up with 47KΩ In case of reprogramming of the module has to be considered the use of the RESET line to start correctly the activity. The preferable configuration is having an external supply for the buffer. Reproduction forbidden without Telit Communications S.p.A.

GE865 Hardware User Guide 1vv0300799 Rev.11 – 13-07-2010 10.1 Electrical Characteristics TIP: Being the microphone circuitry the more noise sensitive, its design and layout must be done with particular care. Both microphone paths are balanced and the OEM circuitry must be balanced designed to reduce the common mode noise typically generated on the ground plane. However the customer can use the unbalanced circuitry for particular application. 10.1.
GE865 Hardware User Guide 1vv0300799 Rev.11 – 13-07-2010 10.1.2 Output Lines TIP : We suggest driving the load differentially , thus the output swing will double and the need for the big output coupling capacitor avoided. However if particular OEM application needs, also a Single Ended (S.E) circuitry can be implemented but the output power will be reduced four times.
GE865 Hardware User Guide 1vv0300799 Rev.11 – 13-07-2010 11 General Purpose I/O The general purpose I/O pads can be configured to act in three different ways: input output alternate function (internally controlled) Input pads can only be read ; they report the digital value (high or low) present on the pad at the read time .

If the digital output of the device to be connected with the GPIO input pad has interface levels different from the 2.8V CMOS, then it can be buffered with an open collector transistor with a 47K pull up to 2.8V.
GE865 Hardware User Guide 1vv0300799 Rev.11 – 13-07-2010 11.5 Using the RFTXMON Output GPIO5 The GPIO5 pin, when configured as RFTXMON Output, is controlled by the GE865 module and will rise when the transmitter is active and fall after the transmitter activity is completed. There are 2 different modes for this function: 1) Active during all the calls: For example, if a call is started, the line will be HIGH during all the conversation and it will be again LOW after hanged up.
