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.
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 MAX9820 to be amplified and then outputted to earphone jack; the digital part of signal I2S is sent to digital audio power amplifier APA3160 to be processed by D/A convertor and power amplifier, then outputted to drive speakers.

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.
2、 AMP IC APA3160 The APA3160 is a digital input, stereo, high efficiency, Class-D audio amplifier available in a TQFP7x7-48P package. The APA3160 accepts the digital serial audio data and using the digital audio processor to convert the audio data becomes the stereo Class-D output speaker amplifier.
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.
Troubleshooting Block Diagram 1．Panel doesn’t light up. Supply with power, check if red indicator lights up in STANDBY state? Press key POWER on remote control or unit, check indicator. Check if 5V is supplied Blue to X601-PIN11 ? Check if level of X601-PIN13 on main Check STANDBY...
