CLK IN Crosstalk

Hi,

   Please refer our ADV7511 layout at https://www.analog.com/media/en/technical-documentation/evaluation-documentation/adv7511_adv7343_eval_layout.pdf for the dimension of the 'Clock in and Video' Signals.

  Also this FAQ presents a general guideline to laying out HDMI traces on circuit boards HDMI Layout Guideline 

Thanks,

Could I know the rise times at least, so I can try to calculate the crosstalk? Rise time is not mentioned in the HW Guide. I presume it depends on the mode but an estimate/minimum/maximum would be nice.

The routing document you sent is not that helpful because it is different than my use case. Im routing the 165 MHz parallel input lines to an FPGA SOM and all the traces on the SOM are differential pairs so Im really concerned about crosstalk.

edit: the HW Guide says that the logic voltage is between 1.8v and 3.3v. Does it depend on the mode? Meaning does the IC expect either 1.8V and 3.3V or anything in between? if anything in between then the coupled crosstalk voltage won't have any effect

edit2: others asked about rise times and you said to use ibis models however all links to get the ibis models are not working. i prefer not to use an ibis model because ive never used one before and probably dont have the software to do so. so i would prefer an estimate

Hi,

The HW Guide says that the logic voltage is between 1.8v and 3.3v. Does it depend on the mode? Meaning does the IC expect either 1.8V and 3.3V or anything in between? if anything in between then the coupled crosstalk voltage won't have any effect

        The part does not cause any issue as long as it operates according to the specification.

        According to the hardware User guide electrical specifications for digital inputs Vih_min = 1.35V and Vih_max = 3.5V.  As long as the input voltage high is within those limits it should work.

       AVDD, DVDD, PVDD, PLVDD needs to be 1.8V

      MVDD (pin 47) needs to be 3.3V

      The digital inputs are 3.3V tolerant.

Kindly refer at  ADV7511 video inputs accept logic levels from 1.8 V to 3.3 V?
