  • Page 18: Working Principle Analysis Of The Unit

    Working principle analysis of the unit PAL/SECAM signal flow 1、 PAL/SECAM analog RF signal from antenna is inputted into TUNER FT2112 which is an analog-digital-integrative model and controlled by main chip MSD209FG through I C bus, the RF signal is demodulated by the TUNER, then CVBS signal and audio difference IF signal SIF are outputted.
  • Page 19 LVDS signal is outputted to drive LCD panel. D-SUB, YPbPr audio signal is processed by circuits of “voltage divided, impedance matching and alternating-current coupling”, then inputted into main chip MSD209FG directly for acoustic effect processing and volume control, now the signal is divided into two signals, one is inputted into earphone amplifier BH3547F to be amplified, then outputted to earphone jack directly, the other is inputted into class-D audio power amplifier TAS5711 to be amplified and then outputted to drive speakers.
