The MC74VHC4052 utilize silicon--gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. These analog multiplexers/demultiplexers control analog voltages that may vary across the complete power supply range (from VCC to VEE). The Channel--Select and Enable inputs are compatible with standard CMOS outputs; with pullup resistors they are compatible with LSTTL outputs. These devices have been designed so that the ON resistance (Ron) is more linear over input voltage than Ron of metal--gate CMOS analog switches. Fast Switching and Propagation Speeds Low Crosstalk Between Switches Diode Protection on All Inputs/Outputs Analog Power Supply Range (VCC -- VEE) = 2.0 to 12.0 V Digital (Control) Power Supply Range (VCC -- GND) = 2.0 to 6.0 V Improved Linearity and Lower ON Resistance Than Metal--Gate Counterparts Low Noise
2.2.2.4.2.
NLAST4599
The NLAST4599 is an advanced high speed CMOS single pole - double throw analog switch fabricated with silicon gate CMOS technology. It achieves high speed propagation delays and low ON resistances while maintaining low power dissipation. This switch controls analog and digital voltages that may vary across the full power-supply range (from VCC to GND). The device has been designed so the ON resistance (RON) is much lower and more linear over input voltage than RON of typical CMOS analog switches. The channel select input structure provides protection when voltages between 0 V and 5.5 V are applied, regardless of the supply voltage. This input structure helps prevent device destruction caused by supply voltage - input/output voltage mismatch, battery backup, hot insertion, etc.

2.2.2.7. SMPS 2.2.2.7.1. PRIMARY BLOCK
AC power applied via AC inlet, line filter components prevent chassis from incoming noise of AC line, also prevents AC line against created noises by TV. Bridge rectifier and bulk capacitor converts AC voltage to DC voltage. Applied DC voltage to primary winding is then swicthed via MOSFET by primary controller in a controlled manner. SMPS controller works on quasi-resonant PWM and gets first supply voltage from AC line (SMPS Controller supply). Controller drives MOSFET according to feedback information supplied by shunt regulator and opto-coupler, according to that information adjusts on-time of MOSFET for
required power. After the start-up in normal operation mode SMPS controller is supplied by SMT. Primary block consist of following main parts, Varistor(R803) Line Filter For EMC (C801,L800,C800), SMPS Controller (IC806) Bridge Rectifier (IC820,IC821,IC822,IC823) Rectifier For SMPS Controller(D818,D819) Bulk Cap (C809) Clamping Circuitry (C810,R820,C811,D824) SMT (Switch Mode Transformer) (TR800), SMT Driver MOSFET (Q802), Current Sense Resistor(R828) Protection Components for MOSFET Failure (D805,D806) 2.2.2.7.1.1. SMPS CONTROLLER (NCP1207)
PWM Current-Mode Controller for Free Running Quasi-Resonant Operation The NCP1207A combines a true current mode modulator and a demagnetization detector to ensure full borderline/critical Conduction Mode in any load/line conditions and minimum drain voltage switching (Quasi-Resonant operation). Due to its inherent skip cycle capability, the
controller enters burst mode as soon as the power demand falls below a predetermined level. As this happens at low peak current, no audible noise can be heard. An internal 8.0 _s timer prevents the free-run frequency to exceed 100 kHz (therefore below the 150 kHz CISPR-22 EMI starting limit), while the skip adjustment capability lets the user select the frequency at which the burst foldback takes place. The Dynamic Self-Supply (DSS) drastically simplifies the transformer design in avoiding the use of an auxiliary winding to supply the NCP1207A. This feature is particularly useful in applications where the output voltage varies during operation (e.g. battery chargers). Due to its high-voltage technology, the IC is directly connected to the high-voltage DC rail. As a result, the short-circuit trip point is not dependent upon any VCC auxiliary level. The transformer core reset detection is done through an auxiliary winding which, brought via a dedicated pin, also enables fast Overvoltage Protection (OVP). Once an OVP has been detected, the IC permanently latches off. Finally, the continuous feedback signal monitoring implemented with an overcurrent fault protection circuitry (OCP) makes the final design rugged and reliable. Features Free-Running Borderline/Critical Mode Quasi-Resonant Operation Current-Mode with Adjustable Skip-Cycle Capability No Auxiliary Winding VCC Operation Auto-Recovery Overcurrent Protection Latching Overvoltage Protection External Latch Triggering, e.g. Via Overtemperature Signal 500 mA Peak Current Source/Sink Capability Undervoltage Lockout for VCC Below 10 V Internal 1.0 ms Soft-Start Internal 8.0 _s Minimum TOFF Adjustable Skip Level Internal Temperature Shutdown

MT1389D Pin Description
2.2.4.2.2.
2.1 Sytem Block Diagram
A sample system block diagram for the MT1389D DVD player board design is shown in the following figurre:
2.2.4.3. Audio Output
The MT1389D supports two-channel and six-channel analog audio output. In a system configuration with six analog outputs, the front left and right channels can be configured to provide the stereo (2 channel) outputs and Dolby Surround, or the left and right front channels for a 5.1 channel surround system. The MT1389D also provides digital output in S/PDIF format. The board supports both optical and coaxial SPDIF outputs.
2.2.4.4. Audio DACS
The MT1389D supports several variations of an I2S type bus, varying the order of the data bits (leading or no leading zero bit, left or right alignment within frame, and MSB or LSB first) is possible using the MT1389D internal configuration registers. The I2S format uses four stereo data lines and three clock lines. The I2S data and clock lines can be connected directly to one or more audio DAC to generate analog audio output. The twochannel DAC is internal. The six channel DAC is PCM1606. The outputs of the DACs are not differential. The buffer circuits use National LM833 op-amps to perform the low-pass filtering and the buffering.
2.2.4.5. Video Interface
Video Display Output
The video output section controls the transfer of video frames stored in memory to the internal TV encoder of the MT1389D. The output section consists of a programmable CRT controller capable of operating either in Master or Slave mode. The video output section features internal line buffers which allow the outgoing luminance and chrominance data to match the internal clock rates with external pixel clock rates, easily facilitating YUV4: 2:2 to YUV4: 2:0 component and sample conversion. A polyphase filter achieves arbitrary horizontal decimation and interpolation.
Video Bus
The video bus has 8 YUV data pins that transfer luminance and chrominance (YUV) pixels in CCIR601 pixel format (4:2:2). In this format, there are half as many chrominance (U or V) pixels per line as luminance (Y) pixels; there are as many chrominance lines as luminance.
Video Post-Processing
The MT1389D video post-processing circuitry provides support for the color conversion, scaling, and filtering functions through a combination of special hardware and software. Horizontal upsampling and filtering is done with a programmable, 7-tap polyphase filter bank for accurate non-integer interpolations. Vertical scaling is achieved by repeating and dropping lines in accordance with the applicable scaling ratio.
Video Timing
The video bus can be clocked either by double pixel clock and clock qualifier or by a single pixel clock. The double clock typically is used for TV displays, the single for computer displays.
2.2.4.6. Flash Memory
The decoder board supports 70ns Flash memories. FLASH_512K_8b The MT1389D permits 8- bit common memory I/O accesses.
2.2.4.7. Serial Eeprom Memory
An I2C serial EEPROM is used to store user configuration (i.e. language preferences, speaker setup, etc.) and software configuration.. Industry standard EEPROM range in size from 1kbit to 256kbit and share the same IC footprint and pinout. The default device is 2kbit, 256kx 8, SOIC8 SGS Thomson ST24C02M1 or equivalent.
2.2.4.8. Audio Interface Audio Sampling Rate and PLL Component Configuration
The MT1389D audio mode configuration is selectable, allowing it to interface directly with low-cost audio DACs and ADCs. The audio port provides a standard I2S interface input and output and S/PDIF (IEC958) audio output. Stereo mode is in I2S format while six channels Dolby Digital (5.1 channel) audio output can be channeled through the S/PDIF. The S/PDIF interface consists of a bi-phase mark encoder, which has low skew. The transmit I2S interface supports the 112, 128, 192, 256, 384, and 512 sampling frequency formats, where sampling frequency Fs is usually 32 kHz, 44.1 kHz, 48 kHz, 96 kHz, or 192 kHz. The audio samples for the I2S transmit interface can be 16, 18, 20, 24, and 32-bit samples. For Linear PCM audio stream format, the MT1389D supports 48 kHz and 96 kHz. Dolby Digital audio only upports 48 kHz. The MT1389D incorporates a built-in programmable analog PLL in the device architecture in order to generate a master audio clock. The MCLK pin is for the audio DAC clock and can either be an output from or an input to the MT1389D. Audio data out (TSD) and audio frame sync (TWS) are clocked out of the MT1389D based on the audio transmit bit clock (TBCK). Audio receive bit clock (RBCK) is used to clock in audio data in (RSD) and audio receive frame sync (RWS).

Table 13 Fabrika Servis ayarlari ( Factory Service settings ) Geometri ayarlari : Service menüsündeki 007-011 satirlar arasindaki 50Hz geometri ayarlari yapildiktan sonra, NTSC offsetlerin belirlenmesi için 016-018 satirlar arasindaki NTSC 60Hz ayarlari yapilir. NTSC ayarlarini her tüp çalimasi için bir kez yapilmasi yeterlidir. Çünkü NTSC ayarlari yapilirken, NTSC offset deerleri hesaplanarak EEPROM da saklanir. 16:9 Zoom modu ayarlarida NTSC ayarlari gibi yapilir ve 16:9 offset deerleri hesaplanarak EEPROM'da saklanir. Daha sonra 50 Hz geometri ayarlari deitirildiinde, 007-011 veya 016-018 satirlar arasinda iken menü tusuna basilarak geometri ayarlari kaydedildiinde, otomatik olarak 16:9 modu, RGB horizontal shift ve NTSC geometri deerleri hesaplanir. RGB horizontal shift offset deerleri koda gömülü haldedir. NTSC ve 16:9 modu offset deeri EEPROM'da saklanmaktadir.
Geometry Adjustment: After adjusting 50Hz geometry items (between 007-011). NTSC 60 Hz geometry items (between 016-018) should be adjusted to determine NTSC 60Hz offset. NTSC offset is automatically calculated and stored in NVM. Later on, if we need to change 50Hz geometry settings, NTSC 60Hz geometry settings is automatically calculated by using NTSC offset. 16:9 mode geometry adjustment works like NTSC 60Hz geometry adjustment. If press to menu button between 007-011 or 016-018 items. New geometry setting is stored and, 16:9 mode, RGB shift and NTSC geometry automatically calculated. RGB shift offset value is stored in software. Only NTSC offset and 16:9 mode offset values are stored in EEPROM. AGC ayari : Tunere 60db yayin verildikten sonra AGCTO iteminin uzerine gelinip mavi tua basildiginda AGC otomatik olarak ayarlanir.
