Overview
The LC74980W is an LCD TV scan converter IC that
converts an NTSC TV signal to an XGA personal
computer video signal. This IC, in conjunction with a
digital decoder, a microcontroller, and an LCD panel, can
easily form an LCD TV video signal-processing circuit
system. Since the LC74980W performs resolution
conversion without an external frame memory, it can
reduce system costs. Since this IC also provides PAL TV
signal input and DTV inputs (480p and 480i formats), it
provides the functions required in the next generation of
LCD TV sets.
Features
NTSC and PAL inputs: 8-bit digital YUV (CCIR 601) input
DTV input: 8-bit digital YCbCr input
Progressive-scan XGA RGB (6 bits per color, two-
phase) signal output
YUV to RGB conversion and YCbCr to RGB conversion
Interlaced to progressive scan conversion
Resolution conversion (enlargement)
Variable display size and display position
(independently settable in the horizontal and vertical
directions)
Image quality adjustments: brightness, contrast, color,
sharpness, color phase, black balance, and white balance
Built-in
γ
correction (programmable LUT technique)
Dithering (8-bit to 6-bit conversion)
Built-in OSD function (8 colors)
I
2
C bus interface
Constant frame-rate processing (identical frame periods
in the input and output signals) adopted so that no
external memory is required.
Specifications
Supply voltage: 3.3 V (input pins are 5 V tolerant)
Maximum operating frequency: 65.0 MHz
Package: SQFP208
Applications
LCD TVs, monitors, and projectors
PDP displays
Digital TV sets (both home and car products)
