PW181 Product Specification General Description The PW181 ImageProcessor is a highly integrated Crystal “system-on-a-chip” that interfaces computer graphics and video inputs in virtually any format to a fixed-frequency flat Video panel display. Video Decoder Input Computer and video images from NTSC/PAL to WUXGA PW181 Display at virtually any refresh rate can be resized to fit on a fixed- AD C / Computer TMDS frequency target display device with any resolution up to WUXGA. Video data from 4:3 aspect ratio NTSC or PAL and 16:9 aspect ratio HDTV or SDTV is supported. Multi- PW181 ROM System Block Diagram region, nonlinear scaling allows these inputs to be resized optimally for the native resolution of the display. Advanced scaling techniques are supported, such as format conversion using multiple programmable regions. Three independent image scalers coupled with frame Features locking circuitry and dual programmable color lookup • Third-generation, two-dimensional filtering techniques tables create sharp images in multiple windows, without • Third-generation, advanced scaling techniques user intervention. • Second-generation Automatic Image Optimization Embedded SDRAM frame buffers and memory controllers • Frame rate conversion perform frame rate conversion and enhanced video • Video processing processing completely on-chip. A separate memory is • On-Screen Display (OSD) dedicated to storage of on-screen display images and • On-chip microprocessor CPU general purpose use. • JTAG debugger and boundary scan Advanced video processing techniques are supported • Picture-in-picture (PIP) using the internal frame buffer, including motion adaptive, • Multi-region, non-linear scaling temporal deinterlacing with film mode detection. When • Hardware 2-wire serial bus support used in combination with the new third-generation scaler, this advanced video processing technology delivers the Applications highest quality video for advanced displays. • Multimedia Displays Both input ports support integrated DVI 1.0 content • Plasma Displays protection using standard DVI receivers. • Digital Television A new advanced OSD Generator with more colors and Device Application Package larger sizes supports more demanding OSD applications, PW181-10V Up to XGA Displays such as on-screen programming guides. When coupled PW181-20V Up to UXGA Displays 352 PBGA with the new, faster, integrated microprocessor, this OSD Generator supports advanced OSD animation techniques. PW181-30V Up to WUXGA Display Programmable features include the user interface, custom start-up screen, all automatic imaging features, and special screen effects.
