DATA SHEET
Silicon Gate CMOS IC
LC749450NW
Overview
Digital RGB Image Processor IC
The LC749450NW RGB image processing IC converts interlaced video signals such as NTSC and PAL to progressive
scan and adjusts the image quality of that signal. Since the LC749450NW can operate at input clock frequencies up to
27 MHz, it is optimal as a pixel display device IC for high-quality high-resolution images. A high image quality
progressive scan signal playback system can be implemented easily by combining the LC749450NW with external
memory (two 16M SDRAMs).
