Hi!

 

I have some questions about ADV7611.

 

===========================================

Q1)

ADI's recommended  is this

******************************************

EQ_DYN_EN(0x96)  : 0x00(Static mode)

EQ_DYN1_LF(0x8D) : 0x04

EQ_DYN1_HF(0x8E) : 0x1E

***********************************************

What will happen if our customer sets?

******************************************

EQ_DYN_EN(0x96)  : 0x01(Dynamic mode)

EQ_DYN1_LF(0x8D) : 0x04

EQ_DYN1_HF(0x8E) : 0x1E

**********************************************

Sometime ADV7611 can not receive HDMI data and the image will be fuzzy?

 

===========================================

Q2)

If our customer sets 

EQ_DYN_EN(0x96)  : 0x01(Dynamic mode)

I think

EQ_DYN1_LF(0x8D) : 0x04

EQ_DYN1_HF(0x8E) : 0x1E

these two resistor does not become effective.

Is my understanding correct?

 

===========================================


Best regards
