Product Number: ADV7611

I unable to find from the datasheet for its thermal resistance junction to case (top), R_jt. The image here is from its datasheet. The ψ_jt is here characterization parameter, not thermal resistance. Unlike ADV7611, R_jt for ADV7511 can be found from its hardware user guide

Hi,

As per expert comment, "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-efficient are not available for the part".

Please refer here ADV7611 Thermal Resistances ( Theta_jc, Theta_jb, and Theta_ja ) - Q&A - Video - EngineerZone (analog.com)

Kindly note that, In newer designs we are moving away from theta_jc and theta_ja and using 'ΨJT' as a more accurate measurement.

Thanks,

Poornima
