Output
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.
