SWITCHING CHARACTERISTICS
• Min / Max characteristics and specifications are guaranteed over all Recommended Operating Conditions .
• Typical characteristics and specifications are measured at nominal supply voltages and T
A
= 25°C.
• VDDA = +3.3V ±10%; GNDA = 0V. All voltages with respect to 0V.
• Logic Levels: Logic 0 = 0V, Logic 1 = VDDA.
Notes: 13. Specified using 10% and 90% points on waveform of interest. Output loaded with 50pF.
14. Oscillator start-up time varies with crystal parameters. This specification does not apply when using an external clock source.
