I have some questions of ADV7392.

Could you please support them?

 

Application: Printer

Device: ADV7392

 

Questions:

(1) Software Reset function

When an user send the command of Software Reset, are any restrictions put on
operation?

For instance, in the case of ADV7403, in the D/S, ADI recommend users to put 5ms
interval before next command.

 

(2) connect ADV7392 to ADV7181C

When we connect ADV7392 to ADV7181C at 16bit (4:2:2), Cb/Cr are upside-down at SD
signal.

The result at HD signal hasn't been checked.

The user succeed to correct the upside-down order by changing the following register setting of ADV7181C.

 

SWPC Swap Pixel Cr/Cb (SDP), Address 0x27, [7]

On the other hand, they haven’t found such a register in ADV7392.

 

     1. Is their way to solve the issue right? Does ADI have another recommending setting?

     2. Why is it upside-down between the two device?

 

Best regards,
