Input
The midpoint is V
The timing waveforms in the AC Electrical Characteristics are tested with a V
maximum of 0.5 V and a V
MODA, MODB, and MODC. These pins are tested using the input levels set forth in
the DC Electrical Characteristics. AC timing specifications that are referenced to a
device input signal are measured in production with respect to the 50% point of the
respective input signal’s transition. DSP56002 output levels are measured with the
production test machine V
respectively.
