Signal flow
1 PAL/SECAM signal flow
Send PAL/SECAM analog RF signal received from antenna to A/D integrative TUNER FT2119 which
is controlled by main chip MSD209GL through I
2
C BUS, then CVBS video signal and SIF audio
difference signal will be outputted after demodulation;
CVBS video signal is sent into main chip MSD209GL to be processed by modules of video decoding,
reversed interlace, video processing and zoom, then LVDS signal will be outputted to drive display
panel;
SIF audio difference signal is sent into main chip MSD209GL to be demodulated to analog video
signal, then it is sent to earphone amplifier BH3547F to be amplified after the processes of
preamplification, acoustic effect processing and volume control, and then one signal is divided into
two, one is sent to earphone jack, the other is sent to sound power amplifier TDA7266SA (class AB)
to be amplified and then drive post speakers.
2 DVB-T signal flow
Send DVB-T digital RF signal received from antenna to A/D integrative TUNER FT2119 which is
controlled by main chip MSD209GL through I
2
C BUS; after down convertion, difference IF signal will
be inputted to demodulating IC MSB1210 to be demodulated; then it will be sent to main chip
MSD209GL with the standard format of serial or parallel TS stream for demultiplexing and decoding;
Video route: digital video signal is sent into main chip MSD209GL for decoding and video processing
after demultiplexing, then LVDS signal will be outputted to drive display panel;
Audio route: digital audio signal will be sent into main chip MSD209GL for decoding and audio
processing after demultiplexing, then dual-sound-track analog audio signal (stereo) is sent to
earphone amplifier BH3547F to be amplified after the processes of preamplification, acoustic effect
processing and volume control by main chip MSD209GL, then one is sent to earphone jack, the
Working principle analysis of the unit
