TDA8217 PAL DECODER AND VIDEO PROCESSOR .. . .. . RGB OUTPUTS SINGLE CHIP CHROMA AND LUMINANCE PROCESSOR DC CONTROL BRIGHTNESS, CONTRAST, AND SATURATION FEW EXTERNAL COMPONENTS FAST BLANKING INPUT FOR OSD INSERTION SUPER SANDCASTLE INPUT DESCRIPTION The TDA8217 is a monolithic integrated color decoder for the PAL standard. It includes in a 20 pins IC all the functions required for the identification and demodulationof PAL signals, and all the videoprocessor functions up to the drive of the video stages. Used with TDA8213 (video & sound IF system) and TDA8214A(H/V deflection circuit), this IC permits a complete low-cost solution for PAL applications.
