Hello.

I have questions about DDC pins (DDC_SDA, DDC_SCL) of ADV7612.

 

Is there allowed "undershoot voltage" of DDC_SDA and DDC_SCL pins in your characterization data?
You don't have to guarantee that.

 

"Digital Inputs Voltage to GND" is "GND - 0.3 V" in ABSOLUTE MAXIMUM RATINGS.
But it's not momentary value but constant value.
We think the pins are able to input signals under -0.3V if it's momentary.
Could you tell me allowed "undershoot voltage" of DDC_SDA, DDC_SCL pin?
You don't have to guarantee that.
We want to know it as just only reference.

 

Thank you!
Best regards.
