Chapter II Operating Principle of Servo Circuit

I. Processing Procedure of Digital Signal

ABS530T(RU) adopts Sanyo double super error correction mechanism and MTK decoding solution, and its servo circuit mainly consists of preposition signal processing, digital servo processing, digital signal processing IC MT1389 and driver circuit BA5954. MT1389 is also a main part of the decoding circuit.

The A, B, C, D, E, F, SA, SB and RFO signal transmitted from the mechanism are mainly inputted through the 2-13 pins of MT1389, and after amplifying treatment of built- in amplifier of MT 1389, the signals are treated in two parts within MT1389:

After being processed by the internal digital servo signal circuit of MT1389, part of the signal forms into corresponding servo control signal, and output focus (FOSO), tracking (TRSO), main shaft (DMSO) and feed (FMSO) servo control signal from the P42, P41, P37 and P38 of MT1389 and send them to the driver circuit BA5954 to amplify the drive. After drive amplification, the signals will drive the focus coil, tracking coil, main shaft motor and feed motor. The focus and tracking servos will be used to adjust the object lens and enable laser beam to identify signal from compact disc correctly; the feed servo will be used to drive the laser head to move longitudinally, and scan the compact disc; the main shaft servo is used to control the main shaft motor to read the signals in constant linear speed and drive the disc to rotate.

After being processed by the internal VGA voltage-controlled amplifier of MT1389 in amplification and balance frequency compensation; another part of the signals is converted into digital signal by the internal A/D converter. When the mechanism reads the CD/VCD signals, these signals will be EFM demodulated in MT1389, and after accomplishing CIRC error regulation in internal MT1389, output to the next grade to carry out audio and video decoding; when the deck reads the DVD signals, these signals will be ESM demodulated in MT1389, and after accomplishing RSPC error regulation in internal MT1389, output to the next grade to carry out audio and

video decoding.

II. Processing Procedure of Control Signal

1. Automatic control of laser power, with the circuit shown as the Figure II:

MT1389 is integrated with APC (automatic light power control) circuit. Its Pin 20 is the pin for inputting VCD laser power rate detection signal, the Pin 21 is the pin for inputting DVD laser power rate detection signal, and the Pin 23 is the pin for outputting VCD laser power rate drive control. When the Pin 23 finds that the laser output power rate is too strong, the output voltage on Pin 23 will increase after the processing of internal circuit of MT1389, and then the conduction degree of V302 (2SB1132) and the voltage on its integration polar will decrease, which consequently lead to the decrease of voltage supplied to the laser tube, the weakening of laser head lighting, and thus achieve the automatic adjustment on laser output power. The Pin 22 is the pin for outputting DVD laser power drive control, with the specific control procedure similar to that of VCD.

2. The tray open/close control circuit is shown as the Figure III:

Figure 3 Different from the circuit in former MTK solution, the MT1389 is integrated with preposition signal processing circuit, so the tray open/close control signals are accomplished by MT1389, that is to say, the close control signal is accomplished by the Pin 51 of MT1389, while the open control signal by Pin 39 of MT1389.

When we press the open button, the Pin 51 of MT1389 is in high power level, while the Pin 39 is in low power level, and then the triode V308 will be on-state. Through resistor R323, the base of V306 will be made to be in low power level, and V306 will be on-state, with the current direction as the following figure:

Power voltage VCC ? V306E-C junction ? motor negative terminal LOAD- ? motor positive Load +? V308 C-E junction ? grounding

So the motor will rotate clockwise to accomplish the action of tray closing.

When we press the open button, the Pin 51 of MT1389 is in low power level, while the Pin 39 is in high power level, and then the triode V307 will be conducted. Through resistor R324, the base of V309 will be made to be in low power level, and V309 will be conducted, with the current direction as the following figure:

Power voltage VCC ? V309E-C junction ? motor negative terminal LOAD- ? motor positive Load +? V307 C-E junction? grounding

So the motor will rotate anti-clockwise to accomplish the action of tray opening.

3. The main shaft motor braking circuit is as the Figure IV:

To prolong the lifespan of motor and reduce the influence of start-up impact current, with the installation of disc, our R&D personnel design the main shaft motor to be in the state of constant operation, so that even if the STOP button is pressed, the disc will not be stopped. Therefore, when we press the OPEN button, a braking signal is required to stop the rotation of main shaft motor immediately to accomplish the opening action in a short time.

During playing, if we press the OPEN button, the main shaft drive signal will disappear, and because of inertia, the main shaft motor is still in operation. As the electromotive force generated in the operation of motor receives the induction voltage on sampling resistors R321 and R340, which, through the resistor R319 and R320, is added to the Pin 36 and Pin 35 of MT1389, and outputted from the Pin 34 after internal processing for amplification in MT1389, and delivered to Pin 47 of MT1389 through R318. After the internal A/D conversion and corresponding processing, an

instant motor reversal braking signal will be outputted from the Pin 37 of MT1389 to stop the rotation of main shaft motor immediately, so as to ensure the standstill of the disc when opening the player.

III. Servo drive circuit

The servo drive of the player is accomplished through a piece of 4-channel dedicated drive circuit BA5954, with the circuit as Figure V:

The 4 servo control signals generated in digital servo circuit processing of MT1389, i.e. focusing control FOSO, tracking control TRSO, feed control FMSO and main shaft control DMSO signals, are added to the pins 1, 26, 23 and 5 of BA5954 respectively, and after drive amplification of BA5954, the focusing and tracking drive signals will be outputted from the pins 13 and 14 and pins 15 and 16 of BA5954 respectively, and added to the focusing and tracking coils to drive the light head to accomplish the actions of focusing and tracking.

The feed and main shaft drive signals will be outputted from the pins 17 and 18 and pins 11 and 12 of BA5954 respectively, and added to the feed motor and main shaft motor to drive the light head to move longitudinally and enable the disc to rotate in constant linear speed.

The STBY on Pin 28 of BA5954 is an output-enabling signal, and only when the pin is in high power level, there will be output of drive voltage on the output terminal.

Chapter III Operating Principle of Decoding Circuit

The decoding circuit of the player mainly consists of decoding chips (including MT1389, SDRAM AE45164016 and FLASH ROM 29LV160BE) and audio DAC CS4360.

I. Control Circuit of System

1. Reset circuit is as the Figure VI:

The reset circuit of the player consists of triode Q204 9014, reset capacitor TC217 100uF/16V and phase inverter U205 HCU04. In starting up, as the terminal voltage of capacitor cannot be changed suddenly, the basic of Q204 is in low power level. After the cut-off of Q204, its emission polar is in low power level, after secondary phase inversion by U205 and regulation, the low power level reset signal is outputted to the Pin 110 of MT1389 to reset MT 1389. When the recharging of TC217 is finished, the base of Q204 will be in high power level, Q204 will be conducted, and the emission polar is in high power level. After the secondary phase inversion and regulation by U205, a high power level is outputted and added to the Pin 110 of MT1389 to maintain high power level during its normal operation.

2. Clock circuit

The crystal oscillator of X201 27MHz, C275/27PF, C276/27PF and phase inverter HCU04 form into clock oscillation circuit, and the clock signals generated are added to the pins 229 and 228 of MT1389 through R244 and 4248 to provide operating clock for MT1389.

3. Data communication circuit

The data communication circuit of the player consists of decoding chip MT1389, SDRAM, AE45164016 and FLASH ROM 29LV160BE, as the Figure VII:

MT1389 is a piece of super large integrated circuit, with the operation voltage of +3.3V and +1.8V. Its functions include: RF small signal preposition processing, digital servo, digital signal processing and accomplishing MPEG decoding and video coding. The built- in MCU of MT1389 is also the system control circuit of the whole player.

AE45164016 is a piece of 4M*16bit large capacity SDRAM, with the operation voltage of +3.3 V. In DV971, the 6ns module is adopted, with high speed and the maximum operation frequency up to 166MHz. Its main function is for operation buffer storage of decoding chip MT1389 to store the audio and video data stream in decoding.

29LV160BE is a piece of 16Mbit FLASH ROM, with the operation voltage of +3.3V, mainly for storing the user’s information including OSD character information, operational microcode and LOGO in start-up.

II. Audio and Video Output Circuit

1. Video output circuit

ABS530T(RU) can not only output three types of interlacing video signal (including CVBS composite video, S terminal Y-C signal and Y/Cb/Cr color difference signal), but also output two types of progressive video signal (including Y/Pb/Pr progressive color difference signal and VGA progressive signal).

The decoding chip MT1389 has built- in video encoding circuit for direct output of analogue composite video signal CVBS, S terminal, color difference signal and VGA signal.

The CVBS composite video signal is outputted from the Pin 198 of MT1389, the S terminal signal Y-C is outputted from the pins 194 and 196 of MT1389, the color difference signal and the R-B-G signal of VGA port is outputted from the pins 203, 202 and 200 of MT1389, the row and field synchronization signals of VGA port are outputted from the pins 207 and 205 of MT1389 respectively.

To mention specifically, the interlacing color difference signal, the progressive color difference signal and progressive R-B-G signal are outputted from the same pin, therefore the signal output shall be selected according to the ports of TV, otherwise there will be only sound but without picture display.

Figure 7

The main function of audio DAC circuit is to convert the digital audio signal decoded from MT1389 into analogue audio signal through D/A converting circuit, and output the audio signal after buffing and amplification to the next amplifying devices to restore it to voice.

The digital audio signals ASDATA0 decoded from MT1389 are outputted from the Pin 217 of MT1389, and delivered to the Pin 2 of audio DAC circuit CS4360. In the mean time, the left and right sound channel clock signal ALRCK, bit clock signal ABCK and the external audio clock signal ACLK required in D/A conversion are outputted from the pins 213, 214 and 215 of MT1389, and added to the pins 5, 3 and 4 of CS4360 respectively.

CS4340 will carry out D/A conversion on the digital audio signals from the channels of SDATA0 under the control of I2C（SDA, SCL） delivered by MT1389, and output the 2-way analogue audio signals from the pins 12 and 15 of CS4340 for the amplification in the next step. The related functions of various signals are as follows:

ASDATA0----Digital audio signal, including the signals of left and right channels

ALRCK-----Left and right bit clock signals, for separating left and right channels

ABCK-----Bit clock signal, for ensuring the accuracy of signal transmission

ACLK-----External clock signal, as the operation clock of CS4340

3. Audio output amplification circuit

The audio digital signals outputted from the decoding board are delivered to the power amplification part for processing after D/A conversion by IC CS4340.

Power amplification parts:

This model carries 2-channel power amplification, and adopts IC TDA7265 to amplify the sound channels. In rated power and the load resistance of 8 ohms, the output power of each sound channel can reach 6W. With the combination of active

The amplifying circuit adopts solely power IC amplification; therefore it has high

integration degree, simple circuit and easy control. The analogue signal outputted from IC4340 will be amplified by IC 4558, and delivered to N103 IC PT2315 for electronic sound volume regulating processing after the left and right sound channels are gated by N102 IC 4052, and then to IC TDA7265 for power amplification, and output.

IC TDA7265 is a double-channel power amplification IC, with standby and muting mode, without switching impact, but with the function of overcurrent and overload protection to prevent the IC from being damaged in abnormalities effectively. The IC can provide the maximum 30W power output for each channel in normal output mode, and when adopting BTL output, the power can reach 50W. Besides, the IC has strong anti-ripple function, and is featured with low power consumption in standby state.

The functions of the pins of IC TDA9843J are as follows:

Mark Pin Function of Pins

-VS 1 Negative supply

OUTPUT1 2 Output of first channel

+VS 3 Positive supply

OUTPUT2 4 Input of second channel

MUTE 5 Mute control line

-VS 6 Negative supply

IN-（2） 8 Channel 2 antiphase input

GND 9 Grounding pin

IN-（1） 10 Channel 1 antiphase input

IN+（1） 11 Channel 1 positive input

Additionally, ABS530T(RU) also has optical and coaxial digital audio output. The digital audio signals after the decompressing of MT1389 are outputted from the Pin 225 of MT1389 in the format of IEC958, and added to the corresponding optical and coaxial terminal output after the regulation by phase inverter HCU04 of U205.

4. Muting and power-off quieting

The muting part of the player is controlled by the SCMUT and LRSWMUT outputted by MT1389. During starting up till reading out the disc, the two controlling lines will output high power level to mute the sound channels. After the disc reads out the signals, MT1389 will alternate the two controlling lines into lower power level to carry out normal signal output. When the remote control muting is pressed, the two controlling lines will be alternated into high power level to realize muting. For this model has just the amplification output of left/right channel, the central mute control line is applied to control the mute of the Karaoke.

5. Automatic Power-on Function

This model is equipped with the IC M41T81, so that it has the function of a clock; just like a clock, when you power it off, it is supplied with the power from one group of battery inside it; when the external power is cut off, the internal power supply is switched on. Therefore, the clock can still work in case of the power cut.

The most distinctive feature of this player is its automatic turnon function. Whenever you want to turn it on, you just preset the turnon time and then set it to a standby status. As a result, when the clock runs to the preset turnon time, the player will give a high level trigger to the STANBY at P50 of 1389, and the player will be turned on. The preset time is stored in the IC 24C02 while the clock is controlled by the 1389 and IC M41T81.

When the MUTE1 is at the high level, the triode V107 is turned on, so that the triode V103 and V104 are turned on, and the left/right channel signal is connected with the grounding, so that the mute is realized therefore.

This mute circuit includes three diodes in parallel connection; among the three control lines, when there is any one at high level, the MUTE signal outputs at low level, so that the power amplifier tube TDA7265 works normally; only when the three control lines are at low level synchronously, the triode V106 cuts off, so that the MUTE

outputs high level and the zener diode on the power board turns on at the reversed direction while the triode V100 turns on and pulls down the voltage at P5 of TDA7265, and finally the complete muting is realized.

In addition, there is a C128 1U/50V capacitor on the peripheral circuit of IC TDA7265 and the mute control line. The start-up mute is realized, for the voltage at both ends of the capacitor can not change abruptly at the very moment when the player is turned on, so as to make the level at the P5 to be low at the very moment of turning on the player. When the player is turned off, this capacitor discharges quickly via the resistor R114 so as to make the level at P5 to become low rapidly, so that the function of turnoff muting is realized.

5. Function of Tuning

ABS530T（RU）has the function of tuning, and can receive RDS signal. The signals of radio reception, the auxiliary channel input signal and the left and right sound signal outputted from CS 4360 are gated through N111IC CD4052, and the controlling A and B are controlled by the low and high power level of AUIN SL0 and AUIN SL1 emitted from MT1389.

The radio head control lines CE, DI, CL and DO are controlled by the array lines connected to MT1389 for the direct control by 1389. When any one of the controlling lines is in abnormality, the radio reception will be in malfunction. The RDS signal received by radio head will be delivered to the dedicated IC SAA6588 for processing.

II. Analysis of Operating Principle

The player adopts linear power for power supply, and is featured with high power, stable power supply and low cost.

After the input voltage is switched via the insulating transformer, the two groups of AC outputs are rectified via the bridge rectifier composed of the VD100, VD101, VD102, VD103 and filtered via the C100, C101, C112 and C113, and then a group of ±20V DC supplies the power to the amplifier IC— such voltage outputs the stable ±12V via the IC 7812 and IC 7912. For the current is purified by two groups of filter capacitor, and the stabilizing IC is for the voltage stabilizing output, therefore the output voltage is relatively stable, with low ripple factor. After the rectifying and filtering, the other group of 8.4V AC voltage outputs +5V CD via the stabilization of IC 1805, then after the filtering and the stabilization via the stabilizing IC BA033, it outputs +3.3V to supply the power to the decoding IC. For this model adopts the linear power supply, and the voltage part and signal amplification part are on the same board, it’s better to process at the power purifying part in order to keep the effect upon the signals from the power supply surge. In doing so, the player can be ensured to have relatively low fluctuation in its service voltage in case of any change to the public power supply, so that the reliability of the player is ensured. The transformer has another group of voltage output, with an AC connecting directly to the panel so as to supply the filament voltage to the display; another group of voltage outputs a group of +27V DC after the rectifying and filtering, so as to supply the grid voltage to the display.

Additionally, this player has the timed power-on function. To ensure some circuits of this player to work normally without the external voltage so as to realize the purpose of timed start function, this player is added with a group of lithium battery supplying 3V voltage, so that the clock can still work normally when the player is turned off. When the power on the player is turned on, the VCC voltage effects on the diode VD118 and the diode cuts off, so the battery can not supply the power to the entire player. When the power on the player is turned off, the VCC is at zero without the external voltage, and the diode is positively conducted, so that the battery supplies the necessary voltage to the working part of the clock on the player to ensure its normal work.

Chapter 5: Panel control and VFD display circuit The panel mainly consists of VFD screen, driver IC6311, IR sensor HS0038A2

and button and indicator display circuit, mainly for accomplishing man-player dialogue and display of operation status.

The structural drawing is as follows:

When the user operates the panel buttons, the control command is sent to the IC 6311 through keyboard-scanning circuit, and through internal decoding drive, the IC 6311 outputs the control data from the pins 5 and 6 (VFDAT) to the built- in CPU of MT1389, which will realize the control on the controlled circuit, and control the VFD through IC 6311.

VFD401 is a vacuum fluorescence screen, and its biggest feature is its high brightness. Its operation principle is similar to the kinescope of TV. The pins 1, 2, 34 and 35 are for filament power supply; the pins 27-32 are GRID poles, each GRID has 16 different characters of display; the pins 4-19 are SEG poles, and the CPU control the SEG poles through its control on UPD6311, and display the characters of corresponding operation status on the screen.
