ADV7403 ADV7842 and ADV7850 chips

I am about to start a composite and s-video signal digitization project. Before i get started i need to establish which of your chips to use. I may as well start with what ever your current chip is as I may have been reading old internet webpages.

I have been looking keenly at your ADV7403 chip. Can you tell me whether this has been updated by your ADV7842 and ADV7850 chips and are there even any later chips than these? I could have easily missed something on your website.

Outputs required are digital(s-pdif)  for PC card capture and HDMI for the TV.  I will also require the 3D comb filter and TBC facilities mentioned for these chips in your datasheets. I will also require stereo inputs for the HDMI TV output.

Thanks

Steve

CODECs come with output DACs but you don't have to connect or use them them.  The key you are looking for is I2S bus, 2 input channels (ADCs) and 192k sampling rate.
