2.6
The timing waveforms shown in the AC electrical characteristics section are tested with a V
minimum of 2.0 V for all pins. AC timing specifications, which are referenced to a device input signal, are measured in
production with respect to the 50% point of the respective input signal’s transition. DSP56720/DSP56721 output levels are
measured with the production test machine V

Fin = External frequency, NF = Multiplication Factor, NR = Predivision Factor, NO = Output Divider
2.8
The DSP56720/DSP56721 system clock is derived from the on-chip oscillator or is externally supplied. To use the on-chip
oscillator, connect a crystal and associated resistor/capacitor components to EXTAL and XTAL; see the example 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
