AC Electrical Characteristics
3.5
The timing waveforms shown in the AC electrical characteristics section are tested with a V
of 0.4 V and a V
referenced to a device input signal, are measured in production with respect to the 50% point of the
respective input signal’s transition. DSP56367 output levels are measured with the production test machine

This characteristic does not apply to PCAP.
The
requirements in Normal 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

In order to obtain these results, all inputs, which are not disconnected at Stop mode, must be terminated (i.e., not allowed to
float).
