The ADV7611 datasheet provides the psi_jt however does not provide any other thermal resistances.
Please provide theta_jc, theta_jb, and theta_ja numbers.
For some time we have specified ADI's video products using the ΨJT thermal co-efficient. We believe that, on a real world PCB, ΨJT yields a much more realistic reflection of the true die temperature. Unfortunately other thermal resistance co-efficients are not available for the part.
We are looking in to your question.
