Initial calibration @ 25 C. Specifications at time of shipment after 48 hours of operation
Frequency stability vs. change in temperature.
Inclusive of frequency stability, supply voltage change (±1%), load change, aging, for 24 hours
Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25°C.
Inclusive of calibration @ 25 C, frequency vs. change in temperature, change in supply voltage (±5%), load change (±5%), reflow soldering process
and 20 years aging, referenced to Fo.
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).
For best performance it is recommended that the circuit connected to this output should have an equivalent input capacitance of 15pF.
