Hello.

 

I have a question about ADC mapping of ADV7181C.

 

Input Condition

Y-> Ain 2

C-> Ain 3

 

I tried to use YC/YC auto mode by the following settings, but it didn't work.

 

[YC/YC auto mode settings as Table 4 in ADV7181C_Manual_RevC]

INSEL[3:0] = 0000

SDM_SEL[1:0] = 11

PRIM_MODE[3:0] = 0000

VID_STD[3:0] = 0010

 

Then I tried to use Manual input muxing mode by the following settings, it worked well.

 

[Manual input muxing mode]

ADC0_SW[3:0] = 0010

ADC1_SW[3:0] = 1100

ADC_SWITCH_MAN = 1

 

Is YC/YC auto mode settings of ADV7181C_Manual correct?

 

Thank you for your cooperation.

 

Best regards.

Kikka
