Chapter 7 Theory of Circuit Operation

The route of D-SUB 15pin input

An RGB (analog) signal is inputted the D-SUB 15pin to the MT5392B which transfers it to a digital
signal by the A/D converter. Then MT5392B generates a Low Voltage Differential Signal (LVDS) for
display device. The Extended Display Identification (EDID) code is recorded in EEPROM.

The route of HDMI CON input

A HDMI (Digital) signal is inputted the HDMI 1&2&3&4 CON to the PI3HDMI245 switch. The
passing signal is processed with the MT5392B. Then MT5392B generates a LVDS for display
device.

The route of HDTV & Component input

HDTV & Component signal is inputted to the MT5392B.After processing, MT5392B generates a
LVDS for display device. The audio signal is inputted

MT5392B. After processing, MT5392B

transmits the signal to audio output. an audio amplifier and line out.

The route of CVBS & S-Video input

The CVBS and S-Video signal is inputted to the MT5392B.After processing, MT5392B generates a
LVDS for display device. The audio signal is also inputted MT5392B. After processing, MT5392B
transmits the signal to audio amplifier. Then, the amplified signal is the output audio signal.

The route of TV input

TV signal is demodulated by the tuner then the demodulating signal is divided into two parts, video
and audio signal. The video signal is processed by MT5392B then MT5392B generates a LVDS for
display device. The audio signal is transmitted in the route named SIF. The SIF signal is
demodulated and decoded by MT5392B. The audio signal is inputted MT5392B. MT5392B
transmits the signal to audio amplifier. Then, the amplified signal is the output audio signal.

The route of DTV input

DTV signal demodulated by the tuner then the demodulating signal is divided into two parts, video
and audio signal. The video signal is demodulated by MT5392B. The demodulated signal is
transmitted to and processed by MT5392B. Also, MT5392B generates a LVDS for display device.
The audio signal is transmitted in the route named FAT-IN. The FAT-IN signal is demodulated and
decoded by MT5392B. After processing, MT5392B transmits the signal to audio amplifier. Then,
the amplified signal is the output audio signal.
