End-to-End Latency of ADV7613 (HDMI Input to LVDS Output

Question

Does anyone know the typical end-to-end latency of the ADV7613, from HDMI input to LVDS output? 
 Any references to datasheets, application notes, or real-world measurements would be appreciated.

Hi, Latency is dependent on the format and what processing is being done on the stream. If you vary the format the latency also varied. In general the image delay will always be much less then one line length measured in pixel clocks. The maximum latency of the Video path for ADV761x : 50 pixel clocks. The maximum latency of the Audio path for ADV761x : 70 audio sample clocks. For example, assuming video is 1080p 60Hz (148.5MHz) Latency for 1920x1080p -- 40-50 pixel clocks ADV761x Video 50 pixel clocks => 148.5MHz (6.73ns) x 50 = 336ns Thanks, Ebin)
