Hi team,

What's the max resolution supported for THS7316? Is the resolution related to video buffer? or it's only related to the video signal source?

    Hello Naizeng,

      The device integrates a 5th -Order Low Pass Filter for DAC reconstruction or ADC image rejection:

    • 36-MHz for HDTV, Y'P'BP'R 720p/1080i, G'B'R' (R'G'B'), and Computer VGA/SVGA/XGA signals.
    • Can also be used for SDTV (480i, 576i, CVBS, S-Video), and EDTV (480p and 576p) signals if desired.

      I am not sure what is meant related to video buffer or video signal source. The resolution is related to closed-loop bandwidth which is set by the integrated 5th order filter in the device, usually 22MHz but this is for lower frame rate (24Hz). If you need 60Hz refresh rate for Full HD, you would need higher closed-loop bandwidth, closer to 72MHz up to 186MHz if you go by the estimate BW = [(Total Pixels x Refresh Rate) /2] x 3. We have devices that can support this refresh rate, such as THS7368/THS7364/THS7372. Here is a link of our video amplifier portfolio with descriptions listed out at this e2e thread: e2e.ti.com/.../opa615-video-clamping-ic-or-video-buffer-with-dc-restoration-function


    Thank you,
