CDCLVD1204/1208 part to part skew vs temperature

Hi,

There is a 600 psec part to part skew spec on these parts that is over temperature (-40 to +85C) and supply voltage.

Does this spec assume that all the parts are at the same temperature, somewhere between -40 to +85C to be met?

Or does it assume one part could be at -40C and the other at +85C and still be met?  If this is the case is there a part to part skew spec that assumes all parts are at the same temperature?

Thanks

    David,

    the app note you referenced is correct, so you are looking 500ps for different voltage/temp conditions and 300ps for devices under identical conditions for the CDCLVD1204.

    Best regards, Falk Alicke
