(ADV7613)Use ADV7613 without HDCP and DDC and Audio.

Hi !

It is the same person as this person with ID(donadona999s).

 

Something is wrong with my login information so I made another ID with my other mail address.

Sorry to confuse you.

 

I already asked about difference between ADV7613 and ADV7613-p.

(ADV7613)What is the difference between ADV7613WBBCZ & ADV7613WBBCZ-P? 

And our customer are planing to use ADV7613.

SoC => HDMI =>  ADV7613 => oLDI

They don't need HDCP and DDC and Audio at their system.

My question is this.

Question)

When our customer don't need to use HDCP, what should they connect to these pins?

If OPEN is OK, please correct my comments.

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

・HPA_A

=> I think Pullup 1k to 5V is OK

     Can they Pullup to 3.3V?

・RXA_5V

=> I think connect to 5V is OK

     Can they Pullup to 3.3V?

・DDCA_SDA

=> I think OPEN or Pullup to 5V is OK.

     Can they Pullup to 3.3V?

・DDCA_SCL

=> I think Pullup 47k to 5V is OK

     Can they Pullup to 3.3V?

・Audio(AP0~AP5、SCLK、MCLKOUT)

=> I think OPEN is OK
・CEC

 => I think OPEN is OK
・CS

 => I think pull down 1k is OK.

  • ADV7613-P has no HDCP keys

    ADV7613WBBCZ and ADV7613WBBCZ-P are both AECQ-100/automotive qualified. The -P means no HDCP keys.

    ・HPA_A pull up 1K to HDMI_5V

    ・RXA_5V connect to HDMI_5V

         

    ・DDCA_SDA I think OPEN or Pullup (using 47k) to 5V is OK, depending on how the connection made to DDCA_SCL is.

         

    ・DDCA_SCL I think Pullup 47k to 5V is OK if and only if DDCA_SDA is open.

         

    ・Audio(AP0~AP5、SCLK、MCLKOUT)I think OPEN/FLOAT is OK


    ・CEC since this pin can be an input or an output, I think is best to pull up to 3.3V using a 1K resistor


    ・CS I think pull down 1k is OK.
