Page 15: Working Principle Analysis
Working Principle of the Unit 1、 ATV PAL signal flow Receive RF PAL analog signal and sent it to XC5200C (D/A silicon Tuner controlled by main chip MSD309PX through I C bus) to be demodulated, then differential IF signal is send out to main chip MSD309PX analog demodulation to be demodulated to get analog CVBS video signal and SIF sound signal. - Page 16 4、 D-SUB/YPbPr input signal flow D-SUB、YPbPr video signal is inputted to main chip MSD309PX to be processed by A/D convertor, video decoder, anti-interlacing part, video processor and zoom controller, then a pair of LVDS signals are outputted to chip MST6M30 to be processed by modules of 120HZ, MEMC and 3D effect, then two pairs of LVDS signals are outputted to drive display panel.

Page 18: Ic Block Diagram
IC Block Diagram 1、 TUNER IC XC5200C The Single-Chip Multi-Standard Tuner XC5200C supports all analog TV formats transmitted worldwide in the 42-1000 MHz band on either cable or terrestrial broadcast channels. It implements on-chip tuning, and channel filtering without external (SAW) filters and has no manually tunable parts. The broadband tuner converts the selected channel into an Intermediate Frequency (IF), which is then sampled by an internal high-resolution analog-to-digital converter (A/D) for further processing. - Page 19 2、 AMP IC TAS5711 The TAS5711 is a 20-W, efficient, digital audio power amplifier for driving stereo bridge-tied speakers. One serial data input allows processing of up to two discrete audio channels and seamless integration to most digital audio processors and MPEG decoders.
- Page 20 3、 AUDIO IC MAX9820 The MAX9820 Windows Vista®-compliant stereo headphone amplifier is designed for portable Equipment where board space is at a premium. It features Maxim’s DirectDrive® architecture to produce a ground-referenced output from a single supply, eliminating the large output-coupling capacitors required by conventional single-supply headphone amplifiers.
