Chapter Two Working Principle of Servo Circuit
1. Digital signal processing
DK1050S uses Sanyo’s double-beam super error correction loader and MTK decoding scheme. Its servo circuit mainly consists of advanced signal processing, digital servo processing, digital signal processing IC MT1389 and drive circuit BA5954, of which MT1389 is also one of the main components of the decoder circuit. Signals A, B, C, D, E, F, SA, SB and RFO, transmitted from the loader, are input from pins 2-13 of MT1389 and, after being amplified via the internal pre-amplifier of MT1389, are divided into two parts in MT1389: One part of these signals, after being processed by MT1389’s internal digital servo signal circuit, form corresponding servo control signals and output control signals focus (FOSO), tracking (TRSO), main axle (DMSO) and feed (FMSO) from MT1389’s Pin P42, Pin P41, Pin P37 and Pin P38 respectively, which are then sent to the drive circuit BA5954 for drive amplification. After drive amplification, these output control signals drive the focus coil, tracking coil, Main axle motor and feed motor respectively. Focus and tracking servos are used for correcting object lens and enable laser beams to correctly read signals from CD; feed servo is used for driving laser head to make radial movement to scan the disk; main axle servo is used to control the Main axle motor to read signals at constant linear velocity to drive the disk. The other part of the signals, after amplification, equal frequency compensation, etc via the internal voltage-controlled amplifier (VCA) of MT1389, are converted by the internal A/D
converter into digital signals and, when the loader reads CD/VCD signals, these signals are EFM demodulated in MT1389 and, after CIRC error correction in MT1389, are output for post audio and video frequency decoding; when the loader reads DVD signals, these signals are ESM demodulated in MT1389 and, after RSPC error correction in MT1389, are sent for post decoding.
2. Control signal processing
1). Laser power auto control. The circuit is as shown in Diagram 2.
Diagram 2 MT1389 has an internally integrated APC (auto optical power control) circuit. Pin 20 is the pin for VCD laser power strength detection signal input, Pin 21 is pin for DVD laser power strength detection signal input and Pin 23 is pin for VCD/CD laser power drive control output. When it is detected by Pin 20 that laser output power is too strong, MT1389’s internal circuit will process it so voltage output by Pin 23 will increase and V302 (2SB1132) conductivity will decrease,then the
collector electrode voltage will drop, the voltage supplied to the laser tube will also drop, the light from the laser head will become weaker, thus automatically adjusting the laser power output. Pin 22 is the pin for DVD laser power drive control output and the control process is similar to that of VCD. 2). Inject/Eject control circuit. The circuit is as shown in Diagram 3.
Diagram 3 What is different form the previous MTK circuit is MT1389 has an internally integrated advanced signal processing circuit, and the inject/eject control signals are processed by MT1389. The inject
control signal are processed by Pin 51 of MT1389 and the eject control signal is processed by Pin 39 of MT1389. When we press the inject button, Pin 51 of MT1389 is high level and Pin 39 is low level. Now, the triode V308 conducts and the passes resistance R323, making the base of V306 low level. V306 also conducts. The direction of current is as shown in the following diagram:
Power supply voltage VCC ? V306 E-C junction? motor positive end LOAD+ ? motor negative end LOAD- ? V308 C-E junction ? ground
So the motor runs clockwise and completes the inject operation. When we press the eject key, Pin 51 of MT1389 is low level and Pin 39 is high level. Now the triode V307 conducts and passes resistance R324, making the base of V309 low level. V309 also conducts. The direction of current is as shown in the following diagram:
Power supply voltage VCC ? V309 E-C junction? motor negative end LOAD+ ? motor positive end LOAD- ? V307 C-E junction ? ground So the motor runs counterclockwise and completes the eject operation.
3). Main axle motor control braking circuit. The circuit is as shown in Diagram 4. In order to extend the service life of the motor and reduce the impact of starting current on the motor, when there is a disk, our R&D personnel design the main axle motor to be always at the status of running, so even if “STOP” key is pressed, the disk will not stop running. This way, when we press the “EJECT” key, a braking signal is needed to immediately stop the main axle motor and the “EJECT” operation can be completed within a short period of time. When it is playing, if we press the “EJECT” key, the main axle drive signal will disappear, but the main axle motor, due to the effect of moment, will still run. At this time, the electromotive force generated by the motor operation can obtain induction voltage on the sampling resistances R321 and R340 and, through resistances R319 and R320, adds them to Pin 36 and Pin 35 of
MT1389, and after internal processing and amplification in MT1389, is output from Pin 34, then
4
sent to Pin 47 of MT1389 via R318. After internal analog/digital conversion and corresponding processing, MT1389 outputs a transient motor anti-braking signal from its Pin 37, thus immediately stopping the main axle motor to ensure that the disk no longer evolves when it is being ejected.
3. Servo drive circuit
The servo drive of this machine uses one 4-channel BA5954 drive circuit. This circuit is specially designed for servo. The circuit is as shown in Diagram 5. MT1389 digital servo circuit generates four servo control signals: Focus control signal, tracking control signal, feed control signal and main axle control signal. These signals are respectively added to Pin 1, Pin 26, Pin 23 and Pin 5 of BA5954. After being amplified by BA5954 drive, the focus control signal and tracking control signal are output from Pin 13, Pin 14 and Pin 15, Pin 16 of BA5954 and then added to the focus and tracking coils to drive the laser head to complete the focus and tracking operations. Feed and main axle drive signals are output from Pin 17, Pin 18 and Pin 11, Pin 12 of BA5954 and then added to the feed motor and main axle motor to drive the laser head to make radial movement and make the disk evolve at constant linear velocity.
Pin 28 (STBY) of BA5954 outputs enable/disable signals. Only when this pin is high level can the output terminal outputs drive voltage.
Chapter Three Working Principle of Decoder Circuit
The decoder circuit of this machine mainly consists of the decoder chips MT1389, SDRAM AE45164016, FLASH ROM 29LV160BE, audio frequency DAC CS4360, etc.
1. System control circuit
1). Resetting circuit is as shown in Diagram 6:
Focus coil
Tracking coil
Feed motor
Main axle motor
Diagram 5
Diagram 6 The resetting circuit of this machine consists of the triode Q204 9014, resetting capacitor TC217 22uF/16V and inverter U205 HCU04. When we open the machine, because the end voltage of the capacitor cannot change suddenly, Q204 base is low level. The emitter of Q204 is low level and, after secondary inversion and trimming by U205, outputs low-level resetting signal to Pin 110 of MT1389 to provide resetting for MT1389. When charging ofTC217 is finished, Q204 base changes to high level and Q204 conducts. Its emitter is high level and, after secondary inversion and trimming by U205, it outputs high level and adds it to Pin 110 of MT1389 to enable it to maintain high level during normal operation.
2). Clock circuit X201 27MHz crystal oscillator, C275/27PF, C276/27PF and inverter HCU04 form the clock oscillation circuit. The clock signal generated passes R244 and R248 and is then added to Pin 229 and Pin 228 of MT1389 to provide MT1389 with working clock.
3). Data communication circuit The data communication circuit of this machine mainly consists of the decoder chip MT1389, SDRAM AE45164016 and FLASH ROM 29LV160BE. It is shown in Diagram 7. MT1389 is a super large-scale integrated circuit, whose working voltages are +3.3V and +1.8V. Its main functions are advanced RF small signal processing, digital servo processing, digital signal processing, MPEG decoding, video decoding, etc. At the same time, the built- in MCU of MT1389 is also the system control circuit of complete machine. AE45164016 is a 4M*16bit large-capacity SDRAM. Its working voltage is +3.3V. The 6ns module used in DV971 is very fast and its maximum working frequency can reach 166MHz. As the working buffer memory of decoder chip MT1389, its main function is to store the audio and video data flows in the time of decoding. 29LV160BE is FLASH ROM, whose capacity is 16Mbit and working voltage is +3.3V. It is mainly used to store user information, such as OSD characters, working micro-codes, starting LOGO, ETC.
2. Audio/video output circuit
1). Video output circuit DK1050S not only outputs three interleave video signals: CVBS composite video signal, S terminal Y-C signal and Y/Cb/Cr color difference signal, but also outputs two line-by-line video signals: Y/Pb/Pr line-by-line color difference signal and VGA line-by-line signal. Its decoder chip MT1389 has a built- in video encoder circuit that can directly outputs analog composite video signal CVBS, S terminal, color-difference signal and VGA signal. CVBS composite video signal is output from Pin 198 of MT1389; S terminal signal Y-C is output from Pin 194 and Pin 196 of MT1389; color difference signal and R-B-G signal in VGA interface are output from Pin 203, Pin 202 and Pin 200 of MT1389; synchronous signals HSYNC and VSYNC of line and field in VGA interface are output respectively from Pin 207 and Pin 205 of MT1389. It must be noted that interleave color difference, line-by-line color difference signal and line-by-line R-B-G signal are output from the same pin. So the corresponding signal output shall be selected through setting according to the port connected to TV; otherwise, there might be sound without picture. 2). Audio output circuit After being processed by MT1389, the audio frequency signal outputs data signals of five audio tracks from its Pin 217, Pin 218 and Pin 219, and outputs clock signals of five channels from its Pin 214 and Pin 215. These signals, after passing IC 74HCT125, are sent to the audio frequency signal processing IC TAS5508 for audio frequency signal processing (see Exhibit for detailed IC data). After that, ten groups of PWM signals are output, six of which are sent to power amplification, two are sent to earphone output and two sent to auxiliary channels. Of the six groups of signals sent to the power amplification IC, the surround sound and super bass share one N13 IC TAS5508 and the main audio track and the middle share N14 IC TAS5508. Signals are amplified in this IC. Because it is digital high-frequency signal amplification, the efficiency is very high and the heating value of power IC is very small. After amplification, the

output is still digital signal, so in order for output in the speaker, the amplified digital signal shall be processed before output. For a PWM signal that contains audio frequency signals, because the high-frequency signal’s frequency is very high and exceeds the hearing of human ear, so we can neglect the influence of high-frequency signals in the process of processing and only restore low-frequency audio frequency signals.
TAS5508 is an advanced 8-channel digital high-performance IC modulated by pulse width. It applies to processing of most audio frequency digital signals and presents good noise coefficients and dynamic range within 20— 20KHZ. Its characteristics are as follows:
(1) Auto control over clock speed and data sampling speed; (2) 8 groups of channels for audio frequency input; (3) 8 groups of PWM output that can be configured into 6-channel stereo sound output line or
8-channel line output; (4) Line output is one group of PWM signals drives one different input open-loop amplifier.
IC TAS5112 is a high-performance audio frequency digital power amplifier. When bridged with a 6-ohm load, each channel can output up to 50W and has a 95DB dynamic range. The distortion is low and power efficiency can reach 90%. The heating value is low. It provides low-voltage protection, hi-temperature protection, over-current protection, etc, and has a built- in drive power adjustment door circuit. It is suitable for home theaters, DVD receivers, mini composite acoustics, etc. Please see the appendix for detailed introduction to IC. When the disk is normally read, the digital signals and clock signals processed from 1389, after selection by IC 74HCT125, are sent to Pins 26-31 of IC TAS5508 for processing. Now, plug in the earphone, the PH-SEL is high level and MUTE, when normally working, is also high level. Pin 37 of TAS5508 is also high level. The oscilloscope can detect all data lines and clock lines. Of the signals from 5508, one group is sent to N8 and N9 and, after processing, is output from the auxiliary channel; one group is sent to the earphone for processing; PWM signals are sent to the amplifier for amplification. When the earphone is plugged in, the PH-SEL signal is peremptorily short circuited to the earth and changes to low level. The amplifier is mute, but the auxiliary channel output is normal. When reading the disk, the system by default selects Karaoke for input. So, when playing the disk, Karaoke can be opened and this machine also has the auto accompaniment function that is realized by software. When playing VCD, if the system detects external input, it automatically shields the human voice signal in the disk and only keeps the accompanying sound. DK1050S has the radio function and can receive RDS signals. Radio head control lines CE, DI, CL and DO, through 28P drop-out lines, are respectively connected to MT1389. When any control line is abnormal, radio function will become abnormal. The RDS signal received by the radio head is sent to special-purpose IC SAA6588 for processing. 3. Auxiliary channel, optical fiber and co-axial input This machine has auxiliary channels, radio function, optical fiber and co-axial external input. This machine has radio function, and auxiliary channel input function and Karaoke function. All external input shall be selected by N3 CD4052 and then undergo the analog/digital conversion via N7 CS5340 and be sent to MT1389 for signal processing. Subsequent processing and output share the same process as normal disk reading signal output. Optical fiber and co-axial signals, after inductance filtering and capacitance filtering, are sent to the
serial audio frequency digital signal to receive the input Pins 4, 12 and 14 of signal IC CS8415. After passing this IC, the serial audio frequency digital signal is converted into PCM signal, which is then output from Pin 16 (sampling rate signal), Pin 17 (clock signal of main track) and Pin 18 (audio frequency digital signal) of IC and sent to IC 1389 for signal processing.
Chapter Four Working Principle of power board
This machine has two groups of power supply. One group supplies power for the decoder board and small-power IC; the other group supplies power for the power amplification IC and the voltage is high. But both groups have the same design principle. Introduction to the principle of circuit The 220V AC current passes the power plug, protector tube, varistor R501 and common mode rejections BC501 and L501 and is added to the integrated bridge rectification circuit. The diode is IN4007 that has a good performance/price ratio and has a higher durable pressure than IN4001. After bridge rectification, 311V is output and flows through TC501 filter, then is respectively added to two transformers and sent to the DRAIN control pin of switch modules U501 and U502. The power supply working voltage of IC is directly rectified, filtered, divided by the resistor and then supplied to IC. Diode D508, capacitor C516 and resister R516 form the absorb circuit to provide windings 1-4 of the transformer with the discharge circuit for reverse electromotive force. Pin FB controlling the IC is the feedback control pin. According to its current, the pulse width’s conduction and starting and ending time are determined to ensure the stability of voltage output. Five branch circuits are coupled to secondary via the transformer.
1. Voltage output from Pins 11 and 13 of transformer T502, after being rectified and filtered, outputs a group of +28V voltage for power amplification IC;
2. Voltage output from Pin 16 of transformer T501, after being rectified and filtered, outputs a group of +12V voltage that, after being rectified by IC LM7805, outputs a group of +5V voltage; 3. Voltage output from Pin 14 of transformer T501, after being rectified and filtered, outputs a +5V voltage to supply one end of coupling amplifier U502;
4. Voltage output from Pin 12 of transformer T501, after being rectified and filtered, outputs a +3.3V voltage and to supply a group of stable voltages for CPU;
5. Voltage output from Pin 9 of transformer T501, after being rectified and filtered, outputs a group of 21V voltage for displayer driver IC. Clamp ZD501 on -21V supplies panel display screen with filament voltage. Voltage to ground of FL+ and FL- is about -16V.
Because the two groups of power switches of the machine have different working principles, here we only analyze the group that supplies CPU with +5V voltage. Feedback sampling of this group of power supply comes from 5V. It supplies the coupling amplifier HS817 via D514 and R517. At the same time, it is divided by R519 and R520 to supply the reference voltage pin R of 2.5V comparator. When 5V is high, the Pin KA of comparator LM17431A conducts, passes photoelectrical coupler HS817 and is sent to the fourth pin of switch IC 5L0380R to reduce the conduction time of internal switch tube, reduce the coupling of transformer, lower the 5V output and achieve the goal of automatic regulation and vice versa. It must be noted that, in this power switch, the two groups of power switches use a base voltage that is different from IC. The group supplying the amplifier outputs a higher voltage, so it uses
LM431 that has better performance and a higher endurable pressure. However, the group supplying 3.3V voltage, because the output voltage is low, uses 17431. Because these two kinds of IC are different, care shall be taken in the process of maintenance to avoid confusion. This machine uses DC switches.
When the power of the machine is just on, voltage output from Pin No.16 of transformer, after being rectified by D507 half wave, generates a 76V high-frequency voltage on silicon-controlled pin 1. This voltage passes capacitors C507 and R513 and is coupled to Pin No.3 of Q501, the same high-frequency voltage. Because of the effect of feedback stable voltage, Pin No.2 of Q501 gets a stable 5V DC voltage. Its wave shape is as follows: It can be seen from the above diagram that when T=t01, Pin P1 of Q501is high level and Pin P3 of Q501 is also high level and Q501 deducts and Pin P3 outputs a 5V DC voltage; when T=t12, Pin P1 of Q501 and Pin P3 of Q501 are low level and, because U2 > U1, Q501 stops and Pin P3 does not output voltage and 5 VDC voltage is supplied by capacitor TC505; At the moment the power is on, the voltage of U1 is 76V. But, because the conduction of silicon-controlled, Pin P2 of Q501shall be maintained at 5V causing the voltage of U1 to drop to around 7V, so other secondary windings do not output. Power switch only outputs CPU5V and the power supply is at the low-load working status. When the machine is open, only 5V is supplied to the panel via transformer coupling and the complete machine is stand-by. When pressing the stand-by on the panel or on the remote controller, Pin 40 of panel IC TP6317 outputs a high level and triode V503 conducts, giving Pole G of Q501a low level and silicon-controlled Q501 stops. Triode V504 conducts and triode V502 stops. Other windings begin to work normally.

Chapter Five Panel Control and VFD Display Circuit The panel mainly consists of the VFD display screen, drive IC TP6317, remote receiving head HSOO38A2, keys control and indicator display circuit. It mainly accomplishes the man-machine dialogue and displays the working status. Diagram of components is as follows:
Under the control of built-in CPU of MT1389 and via VFDST (status), VFDCK (clock) and VFDAT (data), U401 IC TP6317 is controlled to display complete-machine working status and receive the user control command given by TP6317 to control the complete-machine control circuit and enable complete machine to work under designated status. When pressing the user operating panel key, the control command via the key scans the circuit and sends control command to IC TP6317. After internal encoder drive of IC TP6317, control data is output from Pin 5 and Pin 6 (VFDAT) to internal CPU of MT1389 and the CPU controls the controlled circuit and controls VFD via IC TP6317. VFD401 is a vacuum fluorescent display screen. Its most obvious feature is height. Its working princip le is similar to TV display tube. Pins 1, 2, 34 and 35 supply the filament; Pins 27-32 supply the GRID poles. In each GRID there are 16 different characters for display. Pins 4-19 are SEG poles. CPU, through controlling IC TP6317, finally controls SEG poles, thus enabling the characters of working status to display on the display screen.
Remote receiving head circuit mainly consists of remote receiving head HS0038A2. Pin No.1 is for grounding, Pin No.2 is the supply end and Pin No.3 is the output pin for received signals and is directly connected to the CPU inside MT1389 to control corresponding circuit. This machine has the earphone output function. One of the pins inside the earphone is directly connected to TAS5508. When the earphone is plugged in, detection line H-DET is grounded and becomes low level. When Pin 12 of TAS5508 becomes low level, the amplifier partially outputs mute; when it works normally, the detection pin is high level (about 3.3V).

MPEG-1/MPEG–2/MPEG4/JPEG Video decoding. This chip decodes not only VCD and DVD but also MPEG 4 network video. It can also decode “Movie Network” disks and at the same time can read JPEG pictures to play digital albums. In terms of audio frequency, it not only dual decodes AC-3/DTS, but also reads MP3. It can also decode DVD-Audio to achieve a high-resolution tonal quality that is 1000 times higher than CD. Using the built-in 8032 micro processor of the chip, MT1369E can also achieve the system control function of the complete machine, thus greatly simplifying the circuit design.
