Product Specification: PW166B ImageProcessor XGA/SXGA/UXGA Flat Panel Display Controller IC General The PW166B ImageProcessor is a highly integrated "system-on-a-chip" that interfaces analog, digital, and video inputs in virtually any format to a digital projection system or multimedia display. The PW166B is pincompatible with the PW164. An embedded SDRAM frame buffer and memory controller perform frame rate conversion. Computer images from VGA to UXGA at almost any refresh rate can be resized to fit on a fixed-frequency target display device with any resolution up to UXGA with full 24-bit color. The PW166B includes advanced second generation image scaling that provides completely programmable, horizontal and vertical image scaling. Keystoning allows vertical keystoning effects. In addition, non-linear scaling is supported for precise scaling control, with 16:9 aspect ration sources and displays.This high-quality scaling-- coupled with Auto Image Optimization circuitry--provides sharp, full-screen images, centered on the screen, with no manual adjustments required. The PW166B also includes advanced second-generation sync decoding which provides full support for a wide variety of sync types. This includes interlaced, progressive, sync-on-green, and TMDS DE (Data Enable) only. The PW166B ImageProcessor supports NTSC or PAL video data with a 4:3 aspect ratio and 16:9 aspect ratio sources, such as DVD or HDTV. Nonlinear scaling and separate horizontal and vertical scalers allow these inputs to be resized optimally for the native resolution and aspect ratio of the display device. An integrated OSD controller provides bit-mapped based OSDs with 16 colors from a 64K color palette. The OSD controller supports transparent and translucent functions. The PW166B provides a Pulse Width Modulation (PWM) output for low cost backlight or audio control. With reference source code and an on-chip microprocessor, 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.
