In order tobe able to work in the lowest battery values it is importantto verify the losses in the power supplies lines, Flat cableand in the user PCB.The D15 is a GSM phone that transmits in pulses of about 0.5mSany 4mS. The Peak current is about 1.5A.The VCC line will drop down in the TX periods:In order to minimize the ∆ it is recommended to use a shortFlat cable as possible and to put a 1000uF capacitor (ormaximum possible) in the D15 VCC input.5.1.2 Current consumption in D15:In order to design the power supply correctly you need to takein account the current consumption of the D15 in the differentTXTXTXTransmitPeriodsVCC

APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1Exhibit 8425.1.3 How / When to make the unit to wakeup.If the D15 will have no accessories and the unit is camped theD15 will go to a "sleep mode" (current save mode).During this period of time the RS232 is not responding to anycommand from the DTE device.In order to make the unit to wakeup when the DTE will like to communicate with the radio theuser have two options:1. Activate the RTS During all the DTE/DCE dialog. (Internalythe TS line will be activated). After the communicationdisable the RTS in order to go back to sleep mode.2. Activate the TS During all the DTE/DCE dialog. After thecommunication disable the TS in order to go back to sleepmode.Note: If the RTS or TS line will be active all the time theunit will not switch to Sleep mode and the avarage currentconsumption without a call will be arround 50mA.Timing diagrams should be added. - TBD5.2 Audio circuits consideration.The D15 is able to make a voice call as well as Data calls.In voice calls the audio can be routed in a few channels:Digital audio chanel - Audio is sent via the DSC bus.Analog audio channel - Drived externaly to audio devices.Analog audio channel in Hands free mode - D15 sens theaudio out with the Echo canceling ON in the DSP, Externaldrivers are required.The Selection between each one of the channels can be doneaccording to the table XX in paragraph 4.3.2.
APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1Exhibit 8435.2.1 Digital audio.In case of digital audio channel a DCS drives is in used. Theconsideration that should be taken in this case is to be awareof the present of the hook switch. The hook switch willdestinguish if the handset is In/Out of use.There are two DSC bus accessories for audio defined for theD15:External Handset.DHFA - Car Kit for Hands Free.5.2.2 Analog Audio without Handsfree.The D15 will drive the audio out/in in order to allowed avoice call. In order to connect an Headset it is needed toamplified the speaker and microphone channels.An example for these drivers can be seen in Apendix ?? EVboard.Other point to be taken in consideration is the Buzz noiseexisting in GSM phones due to the transmission rate (217Hz).Inorder to minimize this noise the D15 have a separate groundfor the analog circuits.AnalogCircuitsLogicCircuitsPSDigital GroundDigital GroundAnalogGroundCustomer sideD15
APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1Exhibit 844The main problem causing the Buzz is drops in the Ground linebecause the peak current during TX mode. In order to minimizethe Buzz the following acts should be done:- Use short Flat cable.- Connect the analog ground from the D15 to all the analogcircuits in the customer application without connecting themto the power supply ground.- all the capacitors to ground in the audio circuits should beconnected to the analog ground.- Any reference voltage that may be used should have theexternal capacitor connected to the analog ground.5.2.3 Analog Audio with HandsfreeThe audio In/Out from the D15 for analog Handsfree are thesame as for non Handsfree.All the consideration from Paragraph5.2.2 are applicable for this mode too.The additional consideration in this case is to switch the D15DSP to Echo cancelling mode.In oreder to switch to handsfree mode use the RS232 port bysending a switch command.ATS96=1 Echo canceller is activate. (Handsfree)ATS96=0 Echo canceller is disabled. (headset - Default)
APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1Exhibit 8455.3 Data port considerations.5.3.1 Data levels.The D15 data lines are operating in 0 to 5V logic. All theIn/Out signals are bufferd by an MC74VHCT244 buffer.DTR, DSR, RTS, CTS, DCD lines are "1" (active) in 0V and "0"(inactive) in 5V.The signal treshoulds are:Vih 2.0V min.Vil 0.8V max.Voh 4.4V min. @ 50uA or 3.8V min. @ 8mA.Vol 0.1 max. @ 50uA or 0.44V @ 8mA.5.3.2 Select the data mode:The D15 can support two different modes of operation:SoftGsm - For PC applications.RS232 full flow control - General applications.The RS232 is the default mode and no action is needed toswitch to this mode.The SoftGsm require hardware connection to two lines.Down link pin should be connected via 22KOhm to ground.DSC_EN pin should be connected via 22KOhm to ground.
APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1Exhibit 8465.4 SIM lines consideration.The SIM card can be used in 3 different ways: Internaly in theD15, Externaly by connecting a socket in the customerapplication and remotly via the DCS bus.In case of externaly connection the customer concern should befor Full Type Approval that may require submittion for testingin case that the SIM lines will be longer than 10cm.This Paragraph should be completed.5.5 ESD consideration - TBD5.6 Antenna - To take from D10 manual.5.7 Software - TBD5.8 Mechanical - TBD7.
