Differential Delays are defined as calculated results from single ended rise and fall time measurements. This approach in establishing

AC performance specifications has been taken due to limitations of available Automatic Test Equipment (ATE). The calculated ATE

results assume a linear transition between measurement points and are a result of the following

input.
