2.5 AC Electrical Characteristics
The timing waveforms shown in the AC electrical characteristics section are tested with a V
and a V
the previous table. AC timing specifications, which are referenced to a device input signal, are measured in
production with respect to the 50 percent point of the respective input signal transition. DSP56303 output levels are
measured with the production test machine V
Note: Although the minimum value for the frequency of EXTAL is 0 MHz, the device AC test conditions are 15

Internal Clocks
Refers to MODA/IRQA, MODB/IRQB, MODC/IRQC, and MODD/IRQD pins.
Section 4.3 provides a formula to compute the estimated current requirements in Normal mode. In order to obtain these
results, all inputs must be terminated (that is, not allowed to float). Measurements are based on synthetic intensive DSP
benchmarks (see Appendix A). The power consumption numbers in this specification are 90 percent of the measured results
of this benchmark. This reflects typical DSP applications. Typical internal supply current is measured with V
100°C.
In order to obtain these results, all inputs must be terminated (that is, not allowed to float).
In order to obtain these results, all inputs that are not disconnected at Stop mode must be terminated (that is, not allowed to
float). PLL and XTAL signals are disabled during Stop state.
Periodically sampled and not 100 percent tested.
