Ordering number : ENN7713 SANYO Semiconductors DATA SHEET LC74986NWF LC74986NWV Overview CMOS IC LCD TV Scan Converter IC The LC74986NWF and LC74986NWV are video signal processing ICs that perform resolution conversion, interlaced to progressive scan (IP) conversion, and image quality improvement without requiring the use of external field (frame) memory. These ICs can display a wide variety of video signals and formats on a flat panel display. These ICs also provide image quality improvement and adjustment functions to create the optimal image quality for the flat panel display used. They also include an OSD function that displays characters with the sizes optimal for the size of panel used. A flat panel TV monitor with the necessary video signal processing circuits can be formed easily by combining one of these ICs with a video decoder, A/D converters, a microcontroller, and an LCD panel. Features • Multi-source support — NTSC, PAL, and DTV (480i and 480p) inputs — Progressive scan inputs up to XGA (The LC74986NWV supports up to SVGA.) — Supports both RGB and YCbCr (4:4:4 24 bits, 4:2:2 16 bits or 8 bits) inputs (built-in YCbCr to RGB converter). • Resolution conversion — Independent horizontal and vertical expansion and reduction in the horizontal direction — Interlaced to progressive scan conversion • Image quality correction — Sharpness, color, tint, white/black stretch, brightness, contrast, white balance, black balance — Built-in lookup table based gamma correction circuit (Common characteristics for each 8-bit RGB value can be programmed.) • Panel interface — Single RGB 24-bit or 18-bit, or dual RGB 48-bit or 36-bit signal output (built-in dither processing) — Horizontal sync signal, vertical sync signal, data enable signal, and pixel clock outputs • Other features — No external frame memory required (The input and output have the same frame period.) — Built-in OSD function (510 characters, 8 colors, built-in 8-character font RAM) — I2C bus interface (The OSD function can also be controlled over a 3-wire bus.) — Low-power design IC Specifications • • • Supply voltage: I/O: 3.3V, core: 2.5V (LC74986NWF) or 1.8V (LC74986NWV) dual power supply system Maximum operating frequency: 85MHz (LC74986NWF), 40MHz (LC74986NWV) Package: 144-pin SQFP Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications. SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO products described or contained herein.
