Power(SMPS)



1-1-1 Comparison between Linear Power Supply and S.M.P.S.1-1-1 (a) Linear

The output Vs of transformer is determined by the ratio of 1st Np and 2nd Ns.Vs = (Ns/Np) x Vp

Vout is output (DC) by diode and condensor.

Input : Common power to transformer (Vp).

Fig. 1-4

• Waveform/Description



• Advantages and disadvantages of linear power supply

1). Advantages : Little noise because the output waveform of transformer is sine wave.

2) Disadvantages : Additional margin is required because Vs is changed (depending on power source. (The regulator loss is caused by margin design). Greater core size and condenser capacity are needed, because the transformer work son a single power frequency.

1-1-2 (a) AC Power Rectification/Smoothing Terminal

1) PDS01, PDS02, PDS03, PDS04 : Convert AC power to DC(Full wave rectification). 2) PER10, PER10A : Smooth the voltage converted to DC. 3) PCD01 : Noise removal at power input/output. 4) VX80JS : SMPS protection at power surge input.

1) Prevent residual high voltage at the terminals of switch during switch off/Suppress noise. High inverted power occurs at switch (PIC1) off, because of the 1st winding of transformer :(V=-L1 xdi/dt. L1 : Leakage Induction) A very high residual voltage exist on both terminals of PIC1 4, 5~8 pin because dt is a very short.2) SNUBBER circuit protects PIC1 from damage through leakage voltage suppression by RC.

1-1-2 (c) Driving circuitWhen Vin supplied, driving current Ig occurs through the PIC1. By this I1 (=Hfe x Ig) occurs through the PIC1 and the Vb is inducted to base winding coil NB. By inducted Vb, Ib start flow and the VCC voltage of PIC1 is sustained stable. Ib is constant and I1 increases in Proportion to time. After constant time passed Ib become to shortage and PIC1 is cut OFF (S/W OFF).

System Control


1-3-1 OutlineMedia Tek MT1389J is a cost-effective DVD system on chip (SOC) which incorporates advanced features likeMPEG-4 video recorder, high quality TV encoder and state of art deinterlace processing. The Media tek MT1389JEnables consumer electronics manufactures to build high quality , USB2.0,MS/SD/MMC reader, feature rich DVD Player, portable DVD players or any other home entertainment audio/video/devices.Based on media Tek’s world leading DVD player SOC architecture, the MT1389J is the new generation of theDVD player SOC. It integrates the media tek 3rd generation front en digital RF amplifier and the servo/MPEG AV decoder. To enrich the feature of DVD PLAYER, the MT1389J equips a simplified MPEG-4 advanced simple profile (ASP) video recorder to fully support the DivX1 Home Theater profile. The Progressive scan of the MT1389J utilized advanced motion adaptive de interlace algorithm to achieve the best movie/video playback. It also support a 3:2 pull down algorithm to give the best film effect. The 108MHz/12-bit video DAC provides users a whole new viewing experience.


Servo


1-4-1 OutlineSERVO system of DVD is composed of focusing SERVO, Tracking SERVO,SLED Linked SERVO and CLV SERVO (DISC Motor Control SERVO).1) Focusing SERVO : Focuses the optical spot output from object lens onto the surface. Maintains a uniform distance between object lens of Pick-up and disc (for surface vibration of disc). 2) Tracking SERVO: Make the Object lens follow the disc track in use of tacking error signal (created from pick-up).3) SLED Linked SERVO : When the tracking actuator inclines outwardly as the object lens

follows the track during play, the SLED motor moves slightly ( and counteracts the incline).4) CLV SERVO(DISC Motor Control SERVO) : Controls the disc motor to maintain a constant linear velocity ( necessary for RF signal).



1-4-2 Block Diagram

DECK



1-4-3 Operation1) Focusing SERVO

2) Focusing SERVO The focus loop is changed from open loop to closed loop, and the triangular waveform moves the object lens up and down (at pin 17 of MIC1 during Focus SERVO ON.) at that time, S curve is generated in MIC1. Summing signal of PD A,B,C,D, is generated, and zero cross (1.65V) point occurs when S curve is focused and ABCD signal exceeds a preset, constant value. The focus loop is changed to closed loop, and the object lens follows

the disc movement, maintaining a constant distance from the disc. (these operations are same in CD and DVD).

(2) PLAY

When focus loop closes the loop during focus servo on, both pin 13 and 14 of IC3 are controlled by MIC1



2) TRACKING SERVO (1) NORMAL PLAY MODE For DVD Composite : The signal output from PD A,B,C,D of Pick-up, the tracking error Phase difference of A+C and B+D in RIC1, and inputs to MIC1. Then, it is output to MIC1 via digital equalizer, and applied to the tracking actuator through FIC3. Pin 15 of MIC1 is controlled by VREF(approx.1.65V)during normal play. Meanwhile, DVD repeats the track jump from 1 to 4 in inner direction at normal play (because data-read speed from disc is faster than data output speed on screen). For CD,VCD Receive the signal output trough E,F of pick-up. The tracking error signal is similar to DVD.

2) SEARCH Mode: Search mode : Fine seek, (Moving the tracking actuator slightly little bellow 255 track) and coarse search, moving much in use of sled motor. The coarse search will be described in sled linked servo an now, the fine is explained shortly. If the object lens is located near target, cut off the tracking loop and give the control signal as many as desired count to move the tracking actor via MIC1 pin 26 terminal (TRACK_PWM).

3) SLED LINKED SERVO• Normal Play mode Move SLED motor slightly by means of PWM signal in MIC1 pin 23, as tracking actuator moves along with track during play. Control to

move the entire Pick-up as the tracking actuator moves.• Coarse search mode in case of long-distance search (such as chapter search ), MIC1 uses open-loop jump method. Then, read ID an compute the existing track count after input of next track. If the existing track count is within fine seek range, tracking begins using fine seek.

4) CLV SERVO(DISC MOTOR CONTROL SERVO) Detect SYNC signals from R/U in MIC1, and out put PWM signal to MIC1 for constant linear velocity.


DVD Data Processor


1-5-1 Outline

The MT 1389J (highly-integrated device) includes the full front-end disc controller, back-end decoder Functions As well as the host control CPU.The principal off-chip component include the disc drive with its optical pick up, tray sled and spindle drivers and motors,16Mbits of SDRAM, and the audio Digital-to-Analog converters some applications.

In case of general disc refresh, the memory is almost filled up periodically because write rate memory after disc playback and signal process is faster A/V decoder. When the memory is filled, this status is reported by interrupt to main micom, which controls the servo to kick back the pick-up to the previous track after memorizing the last data read from disc until now. It takes some times to jump to the previous track and return to the original (jump location) again. The memory will have an empty space because A/V decoder reads out data of memory.When the memory has an empty space, where data can be processed and written and the pick-up correctly gets to the original location (before kick back location) again, it reads data again avoids the interrupt of data read previously. The basic operation repeats to perform as described above.

MIC1 (A/V decoder with video encoder) diverges from the 27MHz crystal, then generates VSYNC an HSYNC.MIC1( A/V decoder with video encoder), copy guard processing an D/A conversion of 8bit video data internally inputted from video decoder block by MIC1.Video signal converted into analog signal is outputted via amplifier of analog part.

1-6-2 NTSC/PAL Digital Encoder (MT 1389J ; Built in video encode)

MIC1 inputted from pin 161 with 27MHz generates HSYNC an VSYNC which are based on video signal.MIC1 is synchronous signal with decoded video signal and control the output timing of 8bit video signal.The separate signal is encoded to NTSC by control of MIC1.The above signals, which are CVBS (Composite Video Burst Synchronize), Y/Pr and Pb, are outputted from MIC1 directly.In Course of encoding, 8bit data can extend to 10bit or more.To convert the extended data to quantization noise as possible,MIC1adopts 10bit D/A converter.MIC1 perform video en-coding as well as copy protection.
