Chapter 7 Theory of Circuit Operation
The operation of D-SUB 15pin route
The D-SUB 15pin is input analog signal to the MT5372 transfer A/D converter then generates the
vertical and horizontal timing signals for display device.
The operation of HDMII CON route
.Then transfer to the MT5372, the MT5372 generates the vertical and horizontal timing signals for
display device.
The operation of HDTV & Component route
HDTV & Component signal is input to the MT5372 then MT5372 generates the vertical and
horizontal timing signals for display device.
The operation of Video & S-Video route
The Video and S-Video signal is transmission signal to the MT5372 then MT5372 generates the
vertical and horizontal timing signals for display device.
The operation of TV route
TV signal is processes to the tuner and output to MT5372 then MT5372 generates the vertical and
horizontal timing signals for display device. Audio is processes to the tuner output to SIF circuit and
output to MT5372.Then MT5372 process to wm8776 and output to TDA8946AJ transfer to speaker
The operation of DTV route
DTV signal is processes to the tuner and transmission to MT5112 and output signal to MT5372
generates the vertical and horizontal timing signals for display device.
The operation of keypad
There are 7 keys to control and select the function of VX32L and also has one LED to indicate the
status of operation. They are “Power, ▼▲, + -, Input, OSD”.
