AC Electrical Characteristics
The timing waveforms shown in the AC electrical characteristics section are tested with a VIL maximum of 0.8V and a VIH
minimum of 2.0V 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. DSP56371 output levels are measured with the production
test machine VOL and VOH reference levels set at 1.0V and 1.8V, respectively.
NOTE
Although the minimum value for the frequency of EXTAL is 0 MHz (PLL bypassed), the
device AC test conditions are 5 MHz and rated speed.
