I have an ADV7619 (and ADV7511) eval board, and am evaluating both devices. I am having a problem with the ADV7619 with vertical measurements for some specific timings: 720p 24Hz and 720p 30 Hz. When I apply either of these timings the vertical measurements are usually very far off and the vertical filter is reported as not locked (HDMI 0x7 VERTICAL_FILTER_LOCKED and IO 0x6A V_LOCKED_RAW).
I've tried changing various registers to see if this has any effect on this, but it did not.
The source is a QuantumData 882EA signal generator, and I use it regularly to test these timings on other devices. The 720p timings of concern are SMPTE 296M. The generator is putting out a DVI mode signal. I've confirmed that other devices measure these timings from this source correctly.
I note that it seems to be just the filter that is having the problem, since with the output of the eval board's ADV7511 connected to a sink, the sink displays the image properly for both timings.
Is there something that can be done to get correct measurements for these timings?
