Hello,

 

I have questions about "WAIT_UNMUTE" of ADV7611.
It was changed on ADV7611 Reference Manual UG-180 as follows:

 

Rev. C
WAIT_UNMUTE[2:0]
Description
000 (default)   Disables/cancels delayed unmute. Audio unmutes directly after all mute conditions become inactive.
001             Unmutes 250 ms after all mute conditions become inactive.
010             Unmutes 500 ms after all mute conditions become inactive.
011             Unmutes 750 ms after all mute conditions become inactive.
100             Unmutes 1 sec after all mute conditions become inactive.

 

Rev. D
WAIT_UNMUTE[2:0]
000 (default) Disables/cancels delayed unmute. Audio unmutes directly after all mute conditions become inactive.
001           Unmutes 10 ms after all mute conditions become inactive.
010           Unmutes 25 ms after all mute conditions become inactive.
011           Unmutes 50 ms after all mute conditions become inactive.
100           Unmutes 75 ms after all mute conditions become inactive.
101           Unmutes 100 ms after all mute conditions become inactive.
110           Unmutes 250 ms after all mute conditions become inactive.
111           Unmutes 1 sec after all mute conditions become inactive.

 

Question 1:
 Is this change for only ADV7611?
 How about other HDMI receiver devices?
 As long as we confirm some documents, some following devices seem to have the old values yet.
 ADV7612, ADV7613, ADV7614, ADV7619, ADV748x, ADV7850, ADV762x
 Do you have a plan to change the documents of these other HDMI receivers?

 

Question 2:
 Why was the definition of WAIT_UNMUTE changed?
 Could you tell me the reason?

 

Thank you!
Best regards.
