Notes:
1. Includes calibration @ 25°C, frequency stability vs. change in temperature, supply voltage and load variations, shock and
vibration and 10 years aging.
2. BW = 12 KHz to Fo/2 MHz.
3 When the oscillator is disabled the output is at high impedance. Output is enabled with no connection on pad 1.
