Hello.
Our customer tries to convert ADV7320 into ADV7340/7344, because ADV7320 is not recommended for new design.
So, there are some questions.
1)
Is there a document which describes the differences between ADV7320 and ADV7340/7344?
2)
Is the difference between ADV7340 and ADV7344 only DAC resolution?
3)
Regarding register 0x01[6:4](Input Mode), ADV7320 datasheet have 101b and 110b for "SD and HDTV (SD oversampled)" and
"SD and HDTV (HDTV oversampled)" , but it became "Reserved" in ADV7340/7344 datasheet.
How should I set the registers for same function with ADV7340/7344?
4)
Regarding register 0x10[7:3](HD/ED input Mode) in ADV7320 and register 0x30[7:3](ED/HD standard), ADV7320 datasheet have 00001b
for "Async mode", but it was deleted in ADV7340/7344 datasheet.
How should I set the registers for same function with ADV7340/7344?
Thank you for your cooperation.
Kikka
