Specifications at time of shipment after 48 hours of operation 2) Frequency stability vs. change in temperature. 3) Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25°C. 4) Within two hours after reflow. 5) Output is DC coupled. 6) For best performance it is recommended that the circuit connected to this output should have an equivalent input capacitance of 10pF.
