D-SUB/YPbPr input signal flow
D-SUB
、
YPbPr video signal is inputted to main chip MSD309PX to be processed by A/D convertor,
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.
D-SUB
、
YPbP 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 convertor and power amplifier, then outputted to drive
speakers.

HDMI input signal flow
HDMI video signal is inputted to main chip MSD309PX to be processed by video decoder, 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.
HDMI audio signal is sent to main chip MSD309PX to be processed by audio decoder, pre-amplifier,
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 convertor and
power amplifier, then outputted to drive speakers.
