Specifications at time of shipment after 48 hours of operation 2) Frequency stability vs. change in temperature. 3) Inclusive of frequency stability, supply voltage change (±1%), load change, aging, for 24 hours 4) Frequency change after reciprocal temperature ramped over th e operating range. Frequency measured before and after at 25°C. 5) 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. 6) 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 < 1m A ) . 7) For best performance it is recommended that the circuit connected to this output should have an equivalent input capacitance of 15pF.
