TMDS171: Input inter-pair skew tolerance

Part Number: TMDS171

Hallo,

what are the Data Rate and Clock Rate wich the specified input inter-pair skew tolerance value of 1.8ns refers?

1.8ns value is an absolute value, is it possible to refer the value to the Pixel Clock?

Thank you.

Hi Domenico,

Take this parameter as the maximum supported skew independent of the pixel clock.

Hi Garcia,
in my opinion 1.8ns of inter-pair skew delay have a different impact and limitation on the system,
we are working on a 110MHz pixel clock and I suppose a different response respect to 340MHz clock,
so it's more important to know if my application is limited by the attenuation or the inter-pair skew delay values of the cable we are using,
do you agree?

Hi Domenico,

inter-pair skew is usually not mentioned, the cables should follow different parameters.
