THS8083A

      The THS8083A is a complete solution for digitizing video and graphic signals in RGB or YUV/YCbCr color spaces.The device supports pixel rates up to 80 MHz. Therefore, it can be used for PC graphics digitizing up to the VESA standard of XGA (1024 X 768) resolution at 75 Hz screen refresh rate, and in video environments for the digitizing of digital TV formats, including HDTV.The THS8083A is powered from a single 3.3-V supply and integrates a triple high-performance A/D converter with clamping functions and variable gain, independently programmable for each channel. The clamp timing window is provided by an external pulse or can be generated internally. The programmable gain amplifiers consist of coarse and fine gain control blocks. The THS8083A includes slicing circuitry on the Y or G input to support sync-on-green or sync-on-luminance extraction.
      The THS8083A supports the following features:(1)Analog Channels Three digitizing channels, each with independently controllable clamp, PGA, and ADC;(2)PLL;(3)Output Formatter;(4)System;for more details,please find it in our website.
      The THS8083A can be used in LCD desktop monitors and LCD or DMD-based projection systems;Videoconferencing;PCTV set-top boxes, digital TV sets, and multimedia cards; and Scan rate/image resolution converters;Video/graphics digitizing equipment (RGB or YUV-based).
