SECTION 2 GENERAL DESCRIPTIONS
2.1 Multi-band :
CMD-MZ5 support E-GSM 900 and DCS 1800 multi-band functionality.
Because the usage of multi-band depends on network capabilities, the phone is able to operate as a single band mobile in GSM 900 as well as in DCS 1800; In addition, it supports the extra functionality required for multi-band mobile stations: Inter-band/"seamless" hand-over, channel assignment, cell selection and re-selection, all between both bands within a Public Land Mobile Network. The manual and automatic PLMN selection in both bands is given. The user does not need any special action to use the multi-band functionality of the phone. Users are able to manually roam between PLMN's operating in GSM 900 and DCS 1800 bands. The CMD-MZ5 is a phase II, GSM 900 class 4, DCS 1800 class 1 mobile phone. The nominal maximum output power for GSM 900 is 2W, for DCS 1800 1W.

2.2 Real Time Clock (RTC)
The real time clock is integrated into phone.
When the mobile is switched on the RTC is powered via the CPP. When the phone is powered down, the RTC is powered from the main battery via its own low quiescent current regulator. When the main battery is low or removed, a back-up battery keeps the clock alive.

2.3 Vibra Alert Functionality
The vibrator is a 1.3V device. A general port pin of the SC1 controls the switch mode of the vibration motor. It is powered through a regulator by an interface control unit. If the mobile is in the phase of switching on or off the vibrator is off at all times.

2.4 Battery Safety
The battery pack contains a safety circuitry. The charging circuitry and the safety circuitry together guarantee a double fail-safe battery pack. This means that each component can be either short or open and still all the safety requirements will not be violated. The safety concept protects against: Over voltage: The charging is stopped when Battery Voltage (Vbat) reaches 4.24V- 4.3V. The charging resumes when Vbat falls below 4.06V - 4.15V. Under voltage: When the cell voltage drops below 2.5V - 2.7V the cell is disconnected for discharging. Charging is still possible.

2.5 Battery Charging
Standard Battery 620mAh typical Li-ion 1-476-508-11 The phone can be charged even during making phone calls. However, the shortest charging time will be reached when the phone is switched off.

7.1.2 Operational Description
(1) Receiver Section Radio signals received from the antenna located on the top of cabinet enter the RF connector of common connector (CN401) provided at the bottom of cabinet. After they are separated from the signals coming from external units by a mechanical switch, they enter the antenna switch module (CP702). This module separates the signals transmitted/received to/from the antenna by means of the switch, and also selects GSM or DCS band. The received signals are separated here into GSM side and DCS side. The received signals in the GSM band pass through the band-pass filter (SWF702) from CP702 to remove the signals out of the receiving band. Then, the received signals are amplified in the low-noise amplifier using the transistor (Q702). Further, the band-pass filter (SWF704) removes unnecessary signals out of the band. The SWF704 output signals are balanced signals. Thus, the signals from band-pass filter can be entered as balanced signals to the subsequent RF IC IC604 having a balanced input system. Similarly, the received signals in the DCS band pass through the band-pass filter (FL701) from CP702 to remove the signals out of the receiving band. Then, the received signals are amplified in the low-noise amplifier using the transistor (Q701), and further the band-pass filter (SWF703) removes unnecessary signals out of the band. Same as in GSM band, the SWF703 output signals are also balanced signals, so that they can be entered to the IC604 as they are. FL701 is a dielectric filter, while SWF702 to SWF704 are all SAW filters. To prevent characteristic deterioration due to bias point fluctuation at high temperature, the Q701 and Q702 detect current flowing in the transistors using signals at pins 37 to 39 of IC604 and perform the feedback control so that the current flowing in the transistors is constant at all times. Respective input signals in GSM and DCS bands entered to the IC604 are entered to the receiving mixer in the IC604. They are mixed with local signals from VCO601 in the mixer and converted into IF signals in the 440MHz band. The output of IF signals passes through the band-pass filter (SWF601) where unnecessary signals are removed. The SWF601 output signals return to the IC604 again. The SWF601 input/output signals are all balanced signals. The signals in the 440MHz band that returned to the IC604 are adjusted to proper level signals by variable gain amplifier (PGC) in the IC604, and then they are orthogonal-demodulated with 440MHz signal obtained by dividing the oscillation frequency 880MHz by two at the signal reception from VCO602, and they become base band IQ signals in the IC604. The received signals that became base band IQ signals pass through low-pass filter in the IC604 to remove unnecessary signals, and then they are sent to the base band side. The signals sent to the base band side are IQ signals having 1.4V DC offset. (2) Transmitter Section IQ signals transmitted from base band side are modulated into signals in the transmission IF frequency band by an orthogonal modulator in the IC604. IQ signals must have DC offset voltage 1.575V typ. and signal amplitude 500mVp-p. The transmission IF frequency is 195MHz (975MHz/5) when the terminal is in GSM mode, or 325MHz (975MHz/3) in DCS mode. By this modulation, local signals are generated by dividing the oscillation frequency (975MHz) by an internal frequency divider (3/5 switching) at the signal transmission from VCO602. The modulated signals outputted from orthogonal modulator pass through low-pass filter in the IC604, and then they enter the phase comparator of the offset loop system modulator. In the offset loop system modulation, the VCO having same oscillation frequency as transmission frequency is assembled in the phase lock loop, and the reference frequency of this phase lock loop is used as transmission IF frequency to adjust the phase shift of VCO to that of transmission IF frequency. As a result, the same effect as if the phase modulation was applied to the transmission frequency can be attained. Also, the transmission frequency can be selected simultaneously by using the output of VCO mixed down with the frequency divided by VCO601 as a comparison frequency of the phase lock loop. Unlike conventional mix up system, this offset loop system can reduce spurious signals generated in the mixer. The output signals of offset loop are converted into the GMSK modulated signals by the power VCO, VCO801. This VCO has two outputs of GSM band and DCS band, and the operation modes can be switched by signal lines. The output of VCO801 is already GMSK modulated waves of transmission frequency. The output of VCO801 in the GSM band passes through the low-pass filter FL805 where harmonic component is attenuated. As the PA module CP803 has only one input, this output is composed into one in the diplexer FL806. Also, a part of signals returns to the IC604 for the input of phase lock loop. The output of FL806 enters the PA module CP803 via the matching circuit. The CP803 is a power amplifier having dual bands, and which frequency is to be outputted is switched over by the signal lines. This power amplifier has output controllable terminals, so that the output voltage can be controlled according to external voltage. The CP803 generates two outputs, GSM and DCS.

25

These two outputs pass through low-pass filters CP801 and 802 respectively to remove harmonic component. These CP801 and 802 are also used as directional couplers to detect a part of the power amplifier output for the power control. The outputs of CP801 and 802 are entered to the front-end module CP702. This module switches over the transmission, reception, and band, as mentioned previously. The signals entered to the CP702 are outputted from the antenna via reversed route of received signals. The signals detected in the CP801 and 802 are entered to the D803 and D802 respectively, and they are rectified to become DC voltage components. These outputs are composed into one, and it is compared with APC signal from base band in the operation amplifier IC801 to be the signal to control the CP803 so that the output voltage can follow the APC signal. (3) PLL Section The PLL block consists of dual PLL (IC601) and VCO601 and VCO602. The VCO601 is for channel PLL and generates thefollowing oscillation frequencies. GSM band DCS band Transmission Reception Transmission Reception 1370.4 ­ 1439.6MHz 1365.2 ­ 1399.8MHz 1385.2 ­ 1459.8MHz 1365.2 ­ 1439.8MHz 400kHz step 200kHz step 200kHz step 200kHz step

The output of VCO601 is entered to the FL601 and distributed to two outputs. One of these outputs returns to the IC601, and another output is entered to the IC604. In the transmission of GSM band, the signal entered to the IC604 is divided into two internally, and therefore the frequencies of every 400kHz step are used in this case only. The VCO602 is for local PLL and generates the following oscillation frequencies.

Transmission : 975MHz Reception : 880MHz

At the signal transmission, 975MHz is divided into five in the GSM band, or three in the DCS band in the IC604. At the signal reception, 880MHz is always divided into two in the IC604. Each VCO is provided with an external switching transistor so as to control the power supply. (4) TCXO Section The X601 is a VCTCXO module and it oscillates 13MHz reference signal. This oscillation frequency can be finely adjusted by AFC signal from the DSP. The output signal of X601 is given to the IC601 as it is, and also buffered in the Q602 and then supplied to the base band. (5) Power Supply Section The power supply voltage given from the battery side is supplied directly to the power amplifier module (CP803). For other blocks, the power is supplied from the regulator ICs, IC501 and IC502. The IC501 supplies 2.8V to the PLL block, while the IC502 supplies 2.8V to other blocks.

7.3.3 Operational Description
(1) Memory Stick Bock Configuration The memory stick block consists of a CPU (IC101) with the built-in ARM 7 cores + MS I/F, digital signal processing IC (IC301), magic gate IC (IC401), audio path control IC (IC601), A/D and D/A converter (IC501), digital audio I/F (IC801), headphone amplifier (IC701), S-RAM (IC201), CMOS regulator (IC901, IC902, IC903, IC904), SIM I/F (IC205), optical connector, remote control jack, and 64M memory stick. (2) Audio Compression and Expansion Section The audio data are compressed and expanded in the digital signal processing IC (IC301) to support the SDMI (Water Mark compatible). For this purpose, the ATRAC3 system is used, and the compressed data are encrypted in the magic gate IC (IC401), and stored in the memory stick. Also, the expanded data are D/A-converted, and its low frequency components are amplified in the headphone amplifier (IC701) via audio path control IC (IC601), then outputted to the headphone. (3) Magic Gate Section The memory stick recognition is made between magic gage IC (IC401) and magic gate IC in the memory stick via CPU so as to check the memory stick for magic gate compatibility. Further, at the recording, music data compressed in the digital signal processing IC (IC301) are encrypted and stored in the memory stick. Also, at the playing, the encrypted data in the memory stick are decrypted and led to the digital signal processing IC (IC301). (4) Audio Path Control Section The output paths of received audio, played back audio, terminating tone and key tone are switched over to the receiver, headphone, or earphone, and audio signals are mixed and the volume is controlled, then the signals are led to the headphone amplifier. (5) Digital Recording Section Optical digital audio signals entered from optical connector are synchronized in the digital audio interface (IC801) and demodulated into normal format, and led to the digital signal processing IC (IC301) and compressed there. Then, they are encrypted in the magic gate IC (IC401) and stored in the memory stick. (6) Analog Recording Section Analog audio signals entered from optical connector are A/D-converted and led to the digital signal processing IC (IC301) and compressed there, and then they are encrypted in the magic gate IC (IC401) and stored in the memory stick. (7) SIM Interface Section This device is a SIM interface IC (IC205) with the built-in charge pump so as to support both 3V and 5V SIMs. (8) Remote Control Section The remote controller is equipped with the TEL key for originating a call and answering a terminating call, and the microphone for the talk through earphone and the headphone output line. The headphone output line is provided with a 3.5 stereo mini pin jack, and commercial headphones can also be used.
