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
