    EL7300  
    Introduction  
    An LCD monitor is designed for users to get higher image quality and in the mean-time less power  
    consumption than CRT monitor. Usually, an LCD monitor system is composed of a conversion board  
    and a display panel. The conversion board is for input signal processing and for output format  
    display, and the display panel performs different resolution according to input signal resolution set by  
    the user.  
    The conversion board is composed of several functional components, and it can process the RGB  
    signals from a PC VGA card or processes the digital (or video) signal from other sources and then  
    output the processed data to the display panel in various data formats. The major components of the  
    conversion board are ADC, PLL, SCALAR, OSD, and output formatter (specially designed to include  
    a DSP). The digital image market has long been looking for a solution which can have a RGB input  
    processing capability and here comes the EL7300.  
    The EL7300 is a highly integrated single chip solution for the Flat Panel Display applications. A triple-  
    channel ADC, two PLL circuits, one internal OSD, the most advanced scaling engine, and the  
    sophisticated filters are all built in EL7300. An analog input port has been implemented to EL7300 in  
    addition to the digital port, which supports the digital or video input.  
    The EL7300 contains three high resolution and high quality ADCs with low power consumption. It  
    can directly capture RGB graphics signal from PCs and/or workstations, and through the use of the  
    internal PLL such signals will then be converted to 8-bit digital data per channel. (EL7300 is designed  
    to have two independent sets of PLL circuits, the internal PLLs provide for ADC's sampling clock and  
    the panel clock.) The output frequencies range up to the resolution of SXGA with very small jitter  
    (typically equal to 800ps).  
    A 128K-bit SRAM for OSD bitmap memory has been built in EL7300. The maximum resolution is up  
    to 32K pixels in 16 colors or 64K pixels in 4 colors. Theoretically, the user can create any type of  
    shapes, fonts, or logos for OSD windows.  
    To ensure the highest image quality can always be seen on the LCD, the EL7300 performs advanced  
    interpolation algorithm and programmable filters by offering sets of parameters for different images.  
    The digital input port can connect with a video decoder or with a TMDS receiver, and the image can  
    be shown in a full screen image.
