Page 15: Working Principle Analysis Of The Unit
Working principle analysis of the unit 1、 PAL/SECAM signal flow PAL/SECAM signal from antenna is inputted into TUNER FQD1116 which is an analog-digital-integrative model, the analog RF signal is demodulated by the TUNER, then CVBS signal and SIF(sound intermediate frequency) signal are outputted. - Page 16 amplified, now the audio signal is divided into two, one is outputted to earphone jack directly, the other is inputted into class D audio power amplifier R2A15112 to be amplified and then outputted to speakers. 4、 PC/YPbPr signal flow After processed by impedance matching, PC/YPbPr video signal is inputted into main chip MSD209 to be processed by modules of “A/D transform, digital video processing and OSD addition”, then LVDS signal is outputted to drive LCD panel.
