AC Electrical Characteristics
3.5
The timing waveforms shown in the AC electrical characteristics section are tested with a V
of 0.3 V and a V
shown in
signal, are measured in production with respect to the 50% point of the respective input signal’s transition.
DSP56364 output levels are measured with the production test machine V
at 0.4 V and 2.4 V, respectively.

mode. In order to obtain these results, all inputs must be terminated (i.e., not allowed to float). Measurements are based on
synthetic intensive DSP benchmarks. The power consumption numbers in this specification are 90% of the measured results
of this benchmark. This reflects typical DSP applications. Typical internal supply current is measured with V
= 105°C. Maximum internal supply current is measured with V
In order to obtain these results, all inputs must be terminated (i.e., not allowed to float). PLL signal is disabled during Stop
state.
In order to obtain these results, all inputs, which are not disconnected at Stop mode, must be terminated (i.e., not allowed to
float).
