ADV761x: What is the capacitance value of the DDC & CEC pins?

Category: Hardware
Product Number: ADV7611

Hi,all.
We have been asked by our customer for the capacitance values of the DDC and CEC pins.

https://www.analog.com/media/en/technical-documentation/data-sheets/ADV7611.pdf

For example, in the datasheet listed in the url above,only the digital input/output pin capacitance is listed.
There is no capacitance value listed for the 5V tolerant pins.

Could you please the capacitance values of the DDC and CEC pins.

Best Regards

  • Hi,

      Datasheet specifies a general input capacitance of 10pF for digital input. It’s reasonable to infer that the DDC and CEC pins, being part of the digital Input, would have similar capacitance values . The only Digital input of ADV7611 is HDMI, both DDC and CEC pins are features of HDMI .So, i believe input capacitance 10pF refers to both DDC and CEC capacitances .

     Regarding connectivity, Please check our reference schematic.

    Thanks,
    Poornima
