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 following requirements and guidelines for a proper design. 6.1. Power Supply Requirements Condition Nominal Supply Voltage Normal operating Voltage Range Extended operating Voltage Range Value 3.80 V 3.40 V - 4.
GE864GE864 -QUAD V2 / GE864GE864 -DUAL V2 Hardware User Guide 1vv0300875 Rev.1 – 2010-03-29 The GSM system is made in a way that the RF transmission is not continuous but it is packed into bursts at a base frequency of about 216 Hz. The relative current peaks can be as high as about 2A. 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.

A linear regulator can be used. A switching power supply will not be suited because of the low drop out requirements.
GE864GE864 -QUAD V2 / GE864GE864 -DUAL V2 Hardware User Guide 1vv0300875 Rev.1 – 2010-03-29 6.2.1.2. + 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 GE864-QUAD V2 / GE864-DUAL V2.

Battery Source Power Supply Design Guidelines The desired nominal output for the power supply is 3.8V and the maximum voltage allowed is 4.5V. A single 3.7V Li-Ion cell battery type is suited for supplying the power to the Telit GE864-QUAD V2 / GE864-DUAL V2 module. CAUTION: The three cells Ni/Cd or Ni/MH 3,6 V Nom.
GE864GE864 -QUAD V2 / GE864GE864 -DUAL V2 Hardware User Guide 1vv0300875 Rev.1 – 2010-03-29 NOTE: 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.
GE864GE864 -QUAD V2 / GE864GE864 -DUAL V2 Hardware User Guide 1vv0300875 Rev.1 – 2010-03-29 6.2.4. • 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.
GE864GE864 -QUAD V2 / GE864GE864 -DUAL V2 Hardware User Guide 1vv0300875 Rev.1 – 2010-03-29 • In abnormal conditions, the maximum RF output power may be up to 34 dBm. For this particular application, we recommend the customer to involve TTSC (Telit Technical Support Center) in the design phase of the application.

RS232 Level Level T ranslation In order to interface the Telit GE864-QUAD V2 / GE864-DUAL V2 with a PC com port or a RS232 (EIA/TIA-232) application a level translator is required.
GE864GE864 -QUAD V2 / GE864GE864 -DUAL V2 Hardware User Guide 1vv0300875 Rev.1 – 2010-03-29 NOTE: In order to be able to do in circuit reprogramming of the GE864-QUAD V2 / GE864DUAL V2 firmware, the serial port on the Telit GE864-QUAD V2 / GE864-DUAL V2 shall be available for translation into RS232 and either it is controlling device shall be placed into tristate, disconnected or as a gateway for the serial data when module reprogramming occurs.
GE864GE864 -QUAD V2 / GE864GE864 -DUAL V2 Hardware User Guide 1vv0300875 Rev.1 – 2010-03-29 The RS232 serial port lines are usually connected to a DB9 connector with the following layout: 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.

GE864GE864 -QUAD V2 / GE864GE864 -DUAL V2 Hardware User Guide 1vv0300875 Rev.1 – 2010-03-29 NOTE: The UART input line TXD (rx_uart) of the GE864-QUAD V2 / GE864-DUAL V2 is NOT internally pulled up with a resistor, so there may be the need to place an external 47KΩ pull-up resistor, either the DTR (dtr_uart) and RTS (rts_uart) input lines are not pulled up internally, so an external pull-up resistor of 47KΩ may be required.
GE864GE864 -QUAD V2 / GE864GE864 -DUAL V2 Hardware User Guide 1vv0300875 Rev.1 – 2010-03-29 10. Audio Section Overview The first Baseband chip was developed for the cellular phones, which needed two separated amplifiers both in RX and in TX section. A couple of amplifiers had to be used with internal audio transducers while the other couple of amplifiers had to be used with external audio transducers.

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 its particular application. 10.2.1.
GE864GE864 -QUAD V2 / GE864GE864 -DUAL V2 Hardware User Guide 1vv0300875 Rev.1 – 2010-03-29 10.2.2. Output Lines Characteristics TIP: TIP We suggest driving the load differentially from both output drivers, thus the output swing will double and the need for the output coupling capacitor avoided. However if particular OEM application needs also a Single Ended circuitry can be implemented, but the output power will be reduced four times .

GE864GE864 -QUAD V2 / GE864GE864 -DUAL V2 Hardware User Guide 1vv0300875 Rev.1 – 2010-03-29 The disk and diaphragm are attracted to the core by the magnetic field. When an oscillating signal is moved through the coil, it produces a fluctuating magnetic field, which vibrates the diaphragm at a frequency of the drive signal. Thus the sound is produced relative to the frequency applied. Diaphragm movement 1.1.

Indication of Network Service Availability The STAT_LED pin status shows information on the network service availability and Call status. In the GE864-QUAD V2 / GE864-DUAL V2 modules, the STAT_LED usually needs an external transistor to drive an external LED. Therefore, the status indicated in the following table is reversed with respect to the pin status.
