(6) Others
OSD I/F: R, G, B, EN
Clock generator (PLL) incorporated
I2C bus interface incorporated
LSI Specifications
Supply voltage Core: 1.8V, I/O block: 3.3V
Maximum operating frequency: 27MHz
Package: TQFP120
Principal Applications
LCD TV
Analog Input
CVBS
×2ch: Composite video input 2channels
S-Video: S video input 1channel
YCbCr/YPbPr (480i/576i input compatible): Component input 1channel
YC Separation Video Decoder
A video decoder that converts either the NTSC/PAL video signal or component video signal into the digital video
signal is incorporated, which is compatible with the composite video signal, S video signal, and component video
signal (480i).
Resolution Conversion
Two-dimensional IP conversion, and expansion/contraction processings available
1. Interlace progressive conversion (IP conversion)
Two-dimensional IP conversion possible for NTSC/PAL input
2. Horizontal vertical scaler functions
Expansion/contraction to VGA size possible. Expansion/contraction possible independently in horizontal and
vertical directions. Full-screen display and zoom display possible.
Enhancement Functions
Various enhancement functions are available. Picture quality adjustment can be made appropriate to characteristics
of LCD-TV.
1. Adjusting the TV picture quality
1-1. Contour correction (horizontal vertical)
Contour correction of the input luminance signal. Adquate peaks are added around the contour.
In this case, coring adjustment is possible to prevent emphasizing of the peak amount and extremely small
noises.
1-2. Color
Saturation can be adjusted by adjusting the color gain of input color-difference signal.
1-3. Hue
The hue of the screen as a whole can be adjusted.
1-4. Luminance
Luminance of the screen as a whole can be adjusted.
1-5. Contrast
Brightness of the screen as a whole can be adjusted.
