| ( DataSheet : www..com ) PW164A ImageProcessor Flat Panel Display Controller IC The PW164A ImageProcessor is a highly integrated "system-on-a-chip" that interfaces analog, digital, and video inputs in virtually any format to a pixel-based display. Computer and video images from NTSC/PAL to UXGA at virtually any refresh rate can be resized to fit on a fixed-frequency target display device, with any resolution up to SXGA. An embedded SDRAM frame buffer and memory controller perform frame-rate conversion completely on-chip. With an on-chip microprocessor and reference source code, manufacturers can develop feature-rich products with rapid time-to-market. Programmable features include the user interface, custom start-up screen, all automatic imaging features, and special screen effects. Graphics Input Pixelworks provides an unrivaled end-toend product line of system-on-a-chip integrated circuits (ICs), interface ICs, and software for the advanced display market. The Pixelworks product line speeds timeto-market while setting new benchmarks in image quality, broad compatibility, ease of use, and lower overall system cost. Pixelworks' innovative system-on-a-chip ImageProcessors and interface ICs process and optimize video, computer graphics, and Web information for display on flat-panel monitors, projectors, digital televisions, and other advanced display products using LCD, plasma, and Digital Light Processing (DLP) technologies. * * * * RGB 24/48-bit 162 Mpixels/sec maximum input rate Interlaced or progressive inputs Digital sync separator--H+V, Composite, Sync-on-Green support;
