CL865-DUAL Hardware User Guide 1vv0301104 Rev.1 – 2014-03-07 6.3. General Design Rules The principal guidelines for the Power Supply Design embrace three different design steps: 6.3.1.  the electrical design  the thermal design  the PCB layout Electrical Design Guidelines The electrical design of the power supply depends strongly on the power source from which this power is drained. We will distinguish them into three categories: 6.3.2.

CL865-DUAL Hardware User Guide 1vv0301104 Rev.1 – 2014-03-07 An example of linear regulator with 5V input is: 6.3.3. + 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 suitable and must not be used. A switching power supply would be preferable because of its better efficiency, especially with the 1A peak current load represented by CL865.

CL865-DUAL Hardware User Guide 1vv0301104 Rev.1 – 2014-03-07 An example of switching regulator with 12V input is in the below schematic: 6.3.4. 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. A single 3.7V lithium-ion cell battery type is ideal to supply power to the Telit CL865 module. WARNING: The three battery cells (Ni/Cd or Ni/MH 3.6V nom.

CL865-DUAL Hardware User Guide 1vv0301104 Rev.1 – 2014-03-07 6.3.5. Thermal Design Guidelines The thermal design for the power supply heat sink must be done with the following specifications: Average current consumption during CDMA 1x @PWR level max : 620mA NOTE: The average consumption during transmissions depends on the power level at which the device is requested to transmit via the network. The average current consumption hence varies significantly.
PAGE 30
CL865-DUAL Hardware User Guide 1vv0301104 Rev.1 – 2014-03-07 6.3.6. Power Supply PCB layout Guidelines As seen in the electrical design guidelines, the power supply must 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 operation of the circuitry. A misplaced component can be useless or can even decrease the power supply performance.

Analog Audio Interface (AVI) The CL865 provides an analog audio interface; one differential input for audio to be transmitted(Uplink) and a balanced output for audio to be received(Downlink).
PAGE 45
CL865-DUAL Hardware User Guide 1vv0301104 Rev.1 – 2014-03-07 10.1.1. MIC Connection If a “balanced way” is anyway desired, much more care has to be taken to VMIC noise and ground noise. TIP: Since the J-FET transistor inside the microphone acts as RF-detector-amplifier, ask vendor for a microphone with anti-EMI capacitor (usually a 33pF or a 10pF capacitor placed across the output terminals inside the case).

CL865-DUAL Hardware User Guide 1vv0301104 Rev.1 – 2014-03-07 10.1.2. EAR Connection The audio output of the CL865 is balanced, this is helpful to double the level and to reject common mode (click and pop are common mode and therefore rejected). These outputs can drive directly a small loudspeaker with electrical impedance not lower than 32Ohm. TIP: in order to get the maximum audio level at a given output voltage level (dBspl/Vrms), the following breaking through procedure can be used.

Indication of Network Service Availability The STAT_LED pin status shows information on the network service availability and Call status. In the CL865 modules, the STAT_LED usually needs an external transistor to drive an external LED.
PAGE 52
CL865-DUAL Hardware User Guide 1vv0301104 Rev.1 – 2014-03-07 11.6. RTC Bypass Output The CL865 module is provided by an internal RTC section. The RTC function of CL865 cannot be operated with VRTC only because the RTC section is not an independent part in CL865 unlike other Telit’s products. So the external RTC backup capacitor will be also useless and VBATT must be connected to the CL865 to use the RTC feature.
