1. INTRODUCTION 11AK30 is a 90° chassis capable of driving 20"/21" tubes at the appropriate currents. The chassis is capable of operating in PAL, SECAM and NTSC standards. The sound system is capable of giving 5 watts RMS output into a load of 8 ohms. One page, 7 page SIMPLETEXT, TOPTEXT, FASTTEXT and US Closed Caption is also provided. The chassis is equipped with a double-deck 42 pin Scart connector. 2. SMALL SIGNAL PART WITH STV2248: STV2248 video processor is essential for realizing all small signal functions for a color TV receiver. 2.1 Vision IF amplifier3 The vision IF amplifier can demodulate signals with positive and negative modulation. The PLL demodulator is completely alignment-free. Although the VCO (Toko-coil) of the PLL circuit is external, yet the frequency is fixed to the required value by the original manufacturer thus the Toko-coil does not need to be adjusted manually. The setting of the various frequencies (38.9 or 45.75 MHz) can be made via changing the coil itself. 2.2 QSS Sound circuit (QSS versions) The sound IF amplifier is similar to the vision IF amplifier and has an external AGC de-coupling capacitor. The single reference QSS mixer is realised by a multiplier. In this multiplier the SIF signal is converted to the inter-carrier frequency by mixing it with the regenerated picture carrier from the VCO. The mixer output signal is supplied to the output via a high-pass filter for attenuation of the residual video signals. With this system a high performance hi-fi stereo sound processing can be achieved. The AM sound demodulator is realised by a multiplier. The modulated sound IF signal is multiplied in phase with the limited SIF signal. The demodulator output signal is supplied to the output via a low-pass filter for attenuation of the carrier harmonics. The AM signal is supplied to the output via the volume control. 2.3. AM DEMODULATOR The AM demodulated signal results from multiplying the input signal by itself, it is available on AM/FM output. 2.3 FM demodulator and audio amplifier (mono versions): The FM demodulator is realized as narrow-band PLL with external loop filter, which provides the necessary selectivity without using an external band-pass filter. To obtain a good selectivity a linear phase detector and constant input signal amplitude are required. For this reason the intercarrier signal is internally supplied to the demodulator via a gain controlled amplifier and AGC circuit. The nominal frequency of the demodulator is tuned to the required frequency (4.5/5.5/6.0/6.5 MHz) by means of a calibration circuit that uses the clock frequency of the µcontroller/Teletext decoder as a reference. The setting to the wanted frequency is realized by means of the software. It can be read whether the PLL frequency is inside or outside the window and whether the PLL is in lock or not. With this information it is possible to make an automatic search system for the incoming sound frequency. This is realized by means of a software loop that alternate the demodulator to various frequencies, then select the frequency on which a lock

condition has been found. De-emphasis output signal amplitude is independent of the TV standard and has the same value for a frequency deviation of ħ25 kHz at the 4.5 MHz standard and for a deviation of ħ50 kHz for the other standards. When the IF circuit is switched to positive modulation the internal signal on de-emphasis pin is automatically muted. The audio control circuit contains an audio switch and volume control. In the mono inter-carrier sound versions the Automatic Volume Leveling (AVL) function can be activated. The pin to which the external capacitor has to be connected depends on the IC version. For the 90° types the capacitor is connected to the EW output pin (pin 20). When the AVL is active it automatically stabilizes the audio output signal to a certain level. 2.4 Video switching The video processor (STV2248C) has three CVBS inputs and two RGB inputs. The first CVBS input is used for external CVBS from SCART 1, the second is used for either CVBS or Y/C from either SCART2 or BAV/FAV, and the third one is used for internal video. The selection between both external video inputs signals is realized by means of software and hardware switches. 2.5 Synchronization circuit The video processor (STV224X) performs the horizontal and vertical processing. The external horizontal deflection circuit is controlled via the Horizontal output pulse (HOUT). The vertical scanning is performed through an external ramp generator and a vertical power amplifier IC controlled by the Vertical output pulse (VOUT). The main components of the deflection circuit are: · PLL1: the first phase locked loop that locks the internal line frequency reference on the CVBS input signal. It is composed of an integrated VCO (12 MHz) that requires the chroma Reference frequency (4.43MHz or 3.58MHz crystal oscillator reference signal), a divider by 768, a line decoder, and a phase comparator. · PLL2: The second phase locked loop that controls the phase of the horizontal output (Compensation of horizontal deflection transistor storage time variation). Also the horizontal position adjustment is also performed in PLL2. · A vertical pulse extractor. · A vertical countdown system to generate all vertical windows (vertical synchronization window, frame blanking pulses, 50/60Hz identification window...). · Automatic identification of 50/60Hz scanning. · PLL1 time constant control. · Noise detector, video identification circuits, and horizontal coincidence detector. · Vertical output stage including de-interlace function, vertical position control. · Vertical amplitude control voltage output (combined with chroma reference output and Xtal 1 indication). 2.6 Chroma and luminance processing: The chroma decoder is able to demodulate PAL, NTSC and SECAM signals. The decoder dedicated to PAL and NTSC sub-carrier is based on a synchronous demodulator, and an Xtal PLL locked on the phase reference signal (burst). The SECAM demodulation is based on a PLL with automatic calibration loop. The color standard identification is based on the burst recognition. Automatic and forced modes can be selected through the I2C bus. NTSC tint, and auto flesh are controlled through I2C bus. Xtal PLL can handle up to 3 crystals to work in PAL M, PAL N and NTSC M for South America. ACC an ACC overload control the chroma sub-carrier amplitude within 26dB range. Both

ACC s are based on digital systems and do not need external capacitor. All chroma filters are fully integrated and tuned via a PLL locked on Xtal VCO signal. A second PLL is used for accurate fine-tuning of the SECAM bell filter. This tuning is achieved during the frame blanking. An external capacitor memorizes the bell filter tuning voltage. A base-band chroma delay-line rebuilds the missing color line in SECAM and removes transmission phase errors in PAL. The base-band chroma delay line is clocked with 6MHz signal provided by the horizontal scanning VCO. The luminance processor is composed of a chroma trap filter, a luminance delay line, a peaking function with noise coring feature, a black stretch circuit. Trap filter and luminance delay lines are achieved with the use of bi-quad integrated filters, autoaligned via a master filter phase locked loop. 2.7 RGB output circuit: The video processor performs the R, G, B processing. There are three sources: 1. Y,U,V inputs (coming from luma part (Y output), and chroma decoder outputs (R-Y, B-Y outputs). 2. External R,G,B inputs from SCART (converted internally in Y,U,V), with also the possibility to input YUV signals from a DVD player, (YUV specification is Y=0.7 V PP , U= 0.7 V PP , V = 0.7V PP for 100% color bar). 3. Internal R,G,B inputs (for OSD and Teletext display) The main functions of the video part are: - Y,U,V inputs with integrated clamp loop, allowing a DC link with YUV outputs, - External RGB inputs (RGB to YUV conversion), or direct YUV inputs, - Y,U,V switches, - Contrast, saturation, brightness controls, - YUV to RGB matrix, - OSD RGB input stages (with contrast control), - RGB switches, - APR function, - DC adjustment of red and green channels, - Drive adjustments (R, G, B gain), - Digital automatic cut-off loop control, - Manual cut-off capability with I2C adjustments, - Half tone, oversize blanking, external insertion detection, blue screen, - Blanking control and RGB output stages. 2.8 µ-Controller The ST92195 is the micro-controller, which is required for a color TV receiver. ST92195D1 is the version with one page Teletext and ST92195D7 is the one with 7 page Teletext.

GENERAL DESCRIPTION 1.1 MT1389D The MT1389D Progressive Scan DVD-Player Combo Chip is a single-chip MPEG video decoding chip that integrates audio/video stream data processing, TV encoder, four video DACs with Macrovision. copy protection, DVD system navigation, system control and housekeeping functions. The features of this chip can be listed as follows: General Features: · Integrated NTSC/PAL encoder. · DVD-Video, VCD 1.1, 2.0, DIVX 3.x, 4.x, 5.1,DIVX PRO, X-VID and SVCD · Unified track buffer and A/V decoding buffer. · Direct interface of 32-bit SDRAM. · Servo controller and data channel processing. Video Related Features: · Macrovision 7.1 for NTSC/PAL interlaced video. · RGB outputs. · 8-bit CCIR 601 YUV 4:2:2 output. · Decodes MPEG video and MPEG2 main profile at main level. · Maximum input bit rate of 15Mbits/sec Audio Related Features: · Dolby Digital (AC-3) and Dolby Pro Logic. · Dolby Digital S/PDIF digital audio output. · CD-DA. · MP3. 1.2 MEMORY 1.2.1 SDRAM Memory Interface The MT1389D provides a glueless 16-bit interface to DRAM memory devices used as OSD, MPEG stream and video buffer memory for a DVD player. The maximum amount of memory supported is 16 MB of Synchronous DRAM (SDRAM). The memory interface is configurable in depth to support 110-Mb addressing. The memory interface controls access to both external SDRAM memories, which can be the sole unified external read/write memory acting as program and data memory as well as various decoding and display buffers. 1.3 DRIVE INTERFACES The MT1389D supports the DV34 interface, and other RF and servo interfaces used by many types of DVD loaders. These interfaces meet the specifications of many DVD loader manufacturers.

2.1 SYSTEM BLOCK DIAGRAM A sample system block diagram for the MT1389D DVD player board design is shown in the following figure:

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. 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 two-channel 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.

5 .VIDEO INTERFACE 5.1 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. 6. FLASH MEMORY The decoder board supports 70ns Flash memories. FLASH_512K_8b The MT1389D permits 8- bit common memory I/O accesses. 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. 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 outp
