Camera interface to HDMI port

Hello GuenterL,

Thanks for the response, i will go through the ADV7510 details.

Please find attached datasheet of one of the camera module which we intend to use, its a SOC module.

Please let me know your inputs / comments on the same.

Thanks,

Ashutosh.

Set up the module for YUV422 as shown in Figure 23 and the ADV7511 Input ID=3 YCbCr 422 and connect the chips as shown in Table 19..21 depending on the justification you select.  Also setup the ADV7511 for internal DE generation.

Test this out by wiring your camera chip directly to a EVAL-ADV7612-7511 evaluation board with the jumpers removed.  http://ez.analog.com/docs/DOC-1713

Electrically you may need to buffer the data lines up to 3.3V

HDMI transmitters are basically parallel to serial converters with some feature added to handle framing, audio and encryption.  You don't have audio or encryption.  It can handle any pixel clock from 13.5MHz up to 162MHz.

Hello GuenterL,

Thanks for the feedback.

So do you think ADV7510 will suffice or ADV7511 for this application because i could see a bit difference in price in these two chips, so couldnt get why this difference is.

Please let me know your comments.

Thanks,

Ashutosh.

Compare them side by side for you requirements.  The major differences are HDMI 1.3 vs 1.4, ARC support, 4k support and temperature range.  For a camera transmitter I would think you will only need the -P option, not HDCP keys.

You might also look at the ADV7511W which is the automotive version, wider temperature range, smaller package, smaller input bus (24bits)

thanks for the information. I will compare them and decide.

We are going through in detail with camera module and ADV7510 chip to arrive at a basic block digram of the architecture. It will help if you review the same and confirm we are on right track.

We are worried about only one thing, the camera SOC will give out the YUV output but will it also give the timing signals required for the HDMI interface chip or those need to be generated by microcontroller?

Hi GuenterL,

I could find the detailed datasheet for ADV7510/11 in which you have referred to refer table 19-21 for connecting chips in post 3 above. Please share the same if you have.

Thanks

For Table 14-21, look in the ADV7511 Programming Guide  http://ez.analog.com/docs/DOC-1740

or ADV7510 PRogramming guide http://ez.analog.com/docs/DOC-1764

Timing is normally generated by the camera chip, normally V & H syncs minimum.

I'll be glad to review your system.  Either post it here or we can move this discussion to emails for privacy.

Hi GuenterL,

Thanks for the information, as soon as i sent you reply got these 2 docs on website, but still thanks!

Yes it would be better if we move on emails for privacy, please share your email address so as to keep updating and sharing information there.

Thanks.
