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 sent to main chip MSD309PX to be processed by acoustic effect processor and volume controller to get two parts of signals: the analog part of signal is sent to earphone power amplifier BH3547F to be amplified and then outputted to earphone jack; the digital part of signal I2S is sent to digital audio power amplifier TAS5711 to be processed by D/A convertor and power amplifier, then outputted to drive speakers.

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、 Headphone Amplifier BH3547F ●Description BH3547F is one headphone amplifier suitable for portable products. BH3547F has a fixed gain of 6 dB. External resistors for gain setting are not needed. Package of BH3541F, BH3544F, BH3547F, BH3548F is pin-to-pin compatible (SOP8), enable to replace each other easily. BH3547F also has mute functions that make it easy to prevent pop noise when power supply turns on/off.
