Min / Max characteristics and specifications are guaranteed over all operating conditions.
Typical characteristics and specifications are measured at nominal supply voltages and TA = 25 °C.
VA+ = 5 V ±5% VD+ = 3.3 V ±5% or 5 V ±5%; AGND = DGND = 0 V. All voltages with respect to 0 V.
Logic Levels: Logic 0 = 0 V, Logic 1 = VD+.
11. Specified using 10% and 90% points on wave-form of interest. Output loaded with 50 pF.
12. Oscillator start-up time varies with crystal parameters. This specification does not apply when using an external
13. Pulse output timing is specified at MCLK = 4.096 MHz. Current and voltage signals are at unity power factor. See
14. Timing is proportional to the frequency of MCLK.
15. When FREQ2 = 0, FREQ1=1 and FREQ0=1, FOUT will have a typical pulse width of 20 µs at MCLK = 4.096 MHz.
