TVP7002 datasheet

 

Description :

The TVP7002 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 a 60-Hz screen refresh rate, and in video environments for the  digitizing of digital TV formats, including HDTV up to 1080p.

The TVP7002 is powered from 3.3-V and 1.9-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 TVP7002 includes analog slicing circuitry on the SOG inputs to support sync-on-luminance or sync-on-green extraction. In addition, TVP7002 can extract discrete HSYNC and VSYNC from composite sync using a sync slicer. The TVP7002 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 12 MHz to 165 MHz. All programming of the device is done via an industry-standard I2C interface, which supports both reading and writing of register settings. The TVP7002 is available in a space-saving 100-pin TQFP PowerPAD package.

GENERAL DESCRIPTION The AD7790 is a low power, complete analog front end for low frequency measurement applications. It contains a low noise 16-bit ∑-Δ ADC with one differential input that can be buffered or unbuffered along with a digital PGA, which allows gains of 1, 2, 4, and 8. The device operates from an internal clock. Therefore, the user does not have to supply a clock source to the device. The output data rate from the part is software programmable and can be varied from 9.5 Hz to 120 Hz, with the rms noise equal to 1.1 μV at the lower update rate. The internal clock frequency can be divided by a factor of 2, 4, or 8, which leads to a reduction in the current consumption. The update rate, cutoff frequency, and settling time will scale with the clock frequency. The part operates with a power supply from 2.5 V to 5.25 V. When operating from a 3 V supply, the power dissipation for the part is 225 μW maximum. It is housed in a 10-lead MSOP.
