Notes:

9. Specified using 10% and 90% points on waveform of interest.

10. An internal power-on-reset is activated whenever power is applied to the device.

11. Oscillator start-up time varies with the crystal parameters. This specification does not apply when

using an external clock source.

power-on reset time elapses.

13. Calibration can also be initiated by pulsing CAL high while CONV=1.
