The TVP70025I is a complete solution for digitizing video and graphic signals in RGB or YPbPr color spaces.

The device supports pixel rates up to 90 MHz. Therefore, it can be used for PC graphics digitizing up to WXGA

(1440 × 900) resolution at a 60-Hz screen refresh rate, and in video environments for the digitizing of digital TV

formats, including HDTV up to 1080i.

The TVP70025I is powered from 3.3-V and 1.8-V supply and integrates a triple high-performance

analog-to-digital (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

TVP70025I includes analog slicing circuitry on the SOG inputs to support sync-on-luminance or sync-on-green

extraction. In addition, TVP70025I can extract discrete HSYNC and VSYNC from composite sync using a sync

slicer.

The TVP70025I also contains a complete horizontal phase-locked loop (PLL) block to generate a pixel clock from

the HSYNC input. Pixel clock output frequencies range from 9 MHz to 90 MHz.

All programming of the device is done via an industry-standard I2C interface, which supports both reading and

writing of register settings. The TVP70025I is available in a space-saving 100-pin TQFP PowerPAD package.
