Subject: input thresholds for ECL model
Classification: Unclassified
Dear IBIS users,
I am modeling an LVPECL input buffer, using the input_ecl model.
How are the Vinl and Vinh defined?
In the 3.2 buffer spec I see an example of negative values. Are these
referenced to supply voltage?
I cannot find the definition. Can someone tell me where to find it?
I looked at some buffer models of other's, and found that they use
positive values.
With kind regards,
Erik.
