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 TA = 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.
