bulletin cx207 page 3 of 4 revision 20 date 19 nov 2013 notes: 1. frequency stability vs. change in temperature. [(fmax - fmin)/(2*fo)]. 2. initial calibration @ 25c. for ocxo with eft, the control voltage must be fxed. 3. after 30 days of operation 4. inclusive of calibration @ 25c, frequency vs. change in temperature, change in supply voltage (5%), load change (5%), shock and vibration and 20 years aging 5. minimum "power on time" after rail rises from 0 to within +/-5% of vcc = 1 second. vcc ramp rate must be <0.3 volts per millisecond. 6. attention: to achieve optimal frequency stability, and in some cases to meet the specifcation stated on this data sheet, it is required that the circuit connected to this ocxo output must have the equivalent input capacitance that is specifed 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. 7. positive slope. (frequency increases as vc voltage increases. to ensure proper operation of vcocxo's, the control voltage input must be biased the nominal control voltage. failure to bias the vc input will cause an unstable output condition. 8. referenced to fo. phase noise characteristics typical phase noise for doc050f - 010.0m parameter minimum nominal maximum units notes @ 1 hz offset - -67 - dbc/hz @ 10 hz offset - -100 - dbc/hz @ 100 hz offset - -130 - dbc/hz @ 1 khz offset - -148 - dbc/hz @ 10 khz offset - -154 - dbc/hz @ 100 khz offset - -155 - dbc/hz package characteristics doc package package consisting of a fr-4 substrate and ryton-r-4 cover. water resistant package, non-hermetic seal .
