i would like to know which is the minimum (without any data processing) and maximum (with data proccessing) latency between the HDMI data input to video data out of ADV7619.
We don't specify that, but it's on the order of a few video clocks. The ADV7619 doesn't do any data processing aside from something like a color space conversion.
in our application two HDMI transmitters supply two syncronized HDMI video output. Two ADV7619 HDMI receivers decode and provide 16bit+ clock to two host video input ports.
I undestand there isn't any specifications related the latency, on other hand the datasheet of ADV7619 shows a video FIFO on hdmi path decoder and if we know the FIFO depth we could pull out max latency between the two separate but syncronizated flows.
I'll see what I can find out.
That block diagram is very generalized. I'm told the varies by significantly by operating mode, and it's not something we can document unfortunately. You'd need to characterize it for whatever mode you want to work in.
