DESCRIPTION
TVP7001 is a complete solution for digitizing video
and graphic signals in RGB or YPbPr color spaces.
The device supports pixel rates up to 165 MHz.
Therefore, it can be used for PC graphics digitizing
up to the VESA standard of UXGA (1600 × 1200)
resolution at 60 Hz screen refresh rate, and in video
environments for the digitizing of digital TV formats,
including HDTV up to 1080p. TVP7001 can be used
to digitize CVBS and S-video signal with 10-bit ADCs.
The TVP7001 is powered from 3.3-V and 1.8-V
supply and integrates a triple high-performance A/D
converter with clamping functions and variable gain,
independently programmable for each channel. The
clamping timing window is provided by an external
pulse or can be generated internally. The TVP7001
includes analog slicing circuitry on the Y or G input to
support sync-on-luminance or sync-on-green
extraction. In addition, TVP7001 can extract discrete
HSYNC and VSYNC from composite sync using a
sync slicer.
TVP7001 also contains a complete analog PLL block
to generate a pixel clock from the HSYNC input. Pixel
clock output frequencies range from 12 MHz to 165
MHz.
All programming of the part is done via an
industry-standard I²C interface, which supports both
reading and writing of register settings. The TVP7001
is available in a space-saving TQFP 100-pin
PowerPAD package.
