Dear all,

 

I have a question on the ADV 7604 document(ADV7604_RecommendedSettings_Rev 2.5.pdf)
Please tell me about the following.


1. On page 17 of the document, the 1F value is written in 0C register of the AFE Map.
    However, in the table on page 22, 0x0D is recommended write at 0x0C of the AFE Map.
    What are these differences and which are the correct values?


2. A similar question of 0x12 register.
   On page 17 of the document, the 7B value is written in 12 register of the AFE Map.
   However, in the table on page 22, 0x12 is recommended write at 0xFB of the AFE Map.
   For the 0x12 register of AFE Map, a sample script of the evaluation board
   (ADV7604IO_ADV7604CP_ADV7604AFE_ADV7604HDMI_ADV7341B-VER.1.4c_RevA.txt),
   "4 C 12 63; Turn Noise shaping OFF" is written.

 

   When confirming the operation on evaluation board, it seems that 0x63 is correct rather than 0x7B, 0xFB.
   Which value is correct?

 

Thanking you
With best regards and wishes
