LCD TV Scan Converter IC
Preliminary
Overview
The LC74982W is an LCD display scan converter IC that
converts NTSC and PAL TV signals to XGA resolution.
The video signal-processing circuits required to implement
an LCD TV set can be easily formed by combining this IC
with a digital decoder, a microcontroller, and an LCD
panel. Since this IC does not require an external frame
memory for resolution conversion, it can contribute to
minimizing total costs. As additional functionality, it also
provides inputs for personal computer video (up to XGA)
and digital TV (480p/480i). Since LC74982W operation is
based on expansion (resolution increasing) processing,
depending on the input resolution, it can also support use
of, for example, 800 × 600 and 800 × 480 dot resolution
LCD panels. Thus the LC74982W can be used in a wide
range of applications.
Features
• NTSC and PAL input support: 24-bit or 16-bit digital
YCbCr signal input
• PC input support: Personal computer 24-bit digital RGB
signal input at resolutions up to XGA
• DTV (480i / 480p) input: 24-bit or 16-bit digital YCbCr
input
• Two-phase progressive scan RGB 18-bit (24 bit) and 36-
bit (48 bit) signal output
• Simulated increased color-depth processing at 6-bit mode.
Values in parentheses apply in 8-bit mode.
• 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 (LUT technique. Each 8-bit R, G,
and B signal is independently programmable.)
• Built-in OSD function (8 colors, 253 characters)
• I²C 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
• Car television and car video monitors
