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 I2C 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.
CVBS video signal is processed by back-end 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.
SIF sound signal is processed by back-end demodulator to get analog sound signal, then processed by pre-amplifier, acoustic effect processor and volume controller to get two parts of signals: the analog part of signal is sent to earphone amplifier MAX9820 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 converter and power amplifier, then outputted to drive speakers.
2. DVB-T signal flow
Receive RF DVB-T digital signal and sent it to XC5200C (D/A silicon Tuner controlled by main chip MSD309PX through I2C bus) to be processed by down-frequency-conversion, then differential IF signal is send out to main chip MSD309PX digital demodulation to be demodulated, then standard parallel transmission flow is outputted to back-end demultiplexer and decoder to be processed.
Video channel: demultiplexing digital video signal is processed by MSD309PX decoder and video processor, 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.
Audio channel: demultiplexing digital audio signal is processed by MSD309PX decoder and audio processor, then double-sound-track analog audio signal (stereo) is outputted to MSD309PX to be processed by preamplifier, acoustic effect processor and volume controller to get two parts of signals: the analog part of signal is sent to earphone amplifier MAX9820 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 converter and power amplifier, then outputted to drive speakers.
3. AV input signal flow
AV video signal is inputted to main chip MSD309PX to be processed by 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.
AV audio signal is processed by voltage divider, resistance matcher and AC coupler, then 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 TAS5711 to be processed by D/A converter and power amplifier, then outputted to drive speakers.
