Absolute Ratings: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only. The
functional operation of the device at those or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to
conditions outside the "recommended operating conditions" for any extended period of time may adversely impact device reliability and result in failures not covered by
warranty.

Attention: To achieve optimal frequency stability, and in some cases to meet the specification stated on this data sheet, it is required that the circuit connected to this TCXO output
must have the equivalent input capacitance that is specified by the nominal load capacitance. Deviations from the nominal load capacitance will have a graduated effect on the stability
of approximately 20 ppb per pF load difference.
