I have some question about ADV7613.
Can we use 2.2k to pull-up DDCA_SDA , DDCA_SCL , SCL , SDA?
Can you tell us which value should we use for pull-up?
DDC is used only to transfer EDID and HDCP information. If this is a custom design then you might not need DDC at all. 10k or 2.2k pull ups would work fine.
Of course 2.2k for control I2C is great.
For the ADV7613
1) Normally the video source provides the strong pull up of the DDC lines so the ADV7613 side should be weak pull ups to pull the lines to known state when the source is not connected. 10K will do.
2) Chip control I2C normally will have 2.2k pull ups but will work with anything from 1k - 4.7k depending on you system.
Thank you for your answer.
Our customer will use this parts to change the SoC interface HDMI to oLDI.
So there will be no connecter for the HDMI line.
So I think 2.2k will work OK.
How do you think about this?
Thank you for your reply!
