AC Electrical Characteristics
The timing waveforms shown in the AC electrical characteristics section are tested with a VIL maximum of 0.8 V and a VIH
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 VOL and VOH reference levels set at 0.4 V and 2.4 V, respectively.
2.7
Internal Clocks
Internal clock characteristics are listed in Table 5.
2.8
External Clock Operation
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 Figure 9.

Notes:
1. The Current Consumption section provides a formula to compute the estimated current 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 VCORE_VDD = 1.0 V,
VDD_IO = 3.3 V at TJ = 25° C. Maximum internal supply current is measured with VCORE_VDD = 1.10 V, VIO_VDD) = 3.4 V at
TJ = 100°C.
2. In order to obtain these results, all inputs, which are not disconnected at Stop mode, must be terminated (i.e., not allowed
to float).
