The ADV7619 hardware manual states that:-
Xpressview™ technology allows switching between both HDMI input ports in less than 1 second
If both signals are gen-locked (with at most 200 pS of delay between channels), and we bypass the CP engine, what is the fastest switching possible between HDMI inputs ports? And what conditions would we need to guarantee this?
If we use an external MUX (i.e. a very high-speed switch) to switch these channels, what is the quickest DE lock time? And what conditions would we need to guarantee this?
