DESCRIPTION OF BLOCK DIAGRAM
1. Input Selection Circuit
1) Analog Input Selection
This block is composed of BA7657F(U103) and
peripheral devices.
There are analog H/V Syncs. BA7657F IC chooses
one input and outputs selected input through sync
selection pin
This block is composed of GM1501(U402) and
peripheral EEPROM IC(U107,U108).
GM1501(U402) controls peripheral devices through
IIC line.
Major functions are (1) to control Flash memory
through DDC-SCLA, DDC-SDAA of D-sub And (2) to
store EDID data in the EEPROM (U107,U108).
This block is composed of VPC 3230 (U1) and
peripheral devices.
GM 1501 controls this IC through IIC Line.
This IC analyzes input signal of CVBS, Y/C and output
analyzed signal (8bit interlace signal) to De-interlace
block.
Analyzed signal has video control signals like
Contrast, Brightness, Sharpness, Color, tint signals
Including Adaptive Comb Filter.
This block is composed of TPA3004 (U505) and
peripheral devices.
The function of the audio amplifier is that to amplify
audio L/R signal transmitted from audio decoder. The
audio signal is amplified according to pre-defined DC
volume control curve. Also, Headphone amplifier
(Tpa6110, U501) is controlled through Line-out.
6. De-interlacer
This block is composed of FLI 2310(U301) and
peripheral devices.
GM1501 (U402) controls this IC through IIC Line.
And this IC converts 8 Bit Interlaced Y/UV signal and
signal that is from component port and changed to
24bit digital signal to De-interlaced signal.
It output converted signal to Format Converter IC(GM
1501, U402).
circuit that converting analog video signal(0.7Vp-p)
through D-sub(J103) Pin to digital signal.
2) This IC Decode TMDS signals of 8 line from DVI-D
