Frequency stability vs. change in temperature. [±(Fmax - Fmin)/2.Fo]. 3. Inclusive of frequency stability, supply voltage change (±1%), load change, aging, for 24 hours. 4. Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25°C. 5. Inclusive of calibration @ 25C, frequency vs. change in temperature, change in supply voltage (±5%), load change (±5%), reflow soldering process and 20 years aging, referenced to Fo 6. BW = 12 KHz to 20 MHz. 7. Leave Pad 8 unconnected if enable / disable function is not required. When tri-stated, the output stage is disabled but the oscillator and compensation circuit are still active (current consumption < 1 mA). 8. For best performance it is recommended that the circuit connected to this output should have an equivalent input capacitance of 15pF. Specifications subject to change without notice.
