Temperature Compensated Crystal
Controlled Oscillators are designed for use
in S3 Telecom Applications. Through the
use of Analog Temperature Compensation,
this device is capable of holding sub 1-ppm
stabilities over the commercial or the
industrial temperature ranges. All models
meet +/-4.6 ppm accuracies for twenty
years. Three STRATUM 3 compliant model
series are available.

Note
1) TCXO: Initial calibration @ /5°C. Specifications at time of shipment after 48 hours of operation.
/) Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at /5°C.
3) Inclusive of calibration @ /5°C, frequency vs. change in temperature, change in supply voltage ±± 5ꢃ), load change ±± 5ꢃ), reflow soldering process
and /0 years aging.
4) For best in application performance, careful selection of an eꢀternal power source is critical. Select an eꢀternal regulator that meets or eꢀceeds to
following specifications regarding voltage regulation tolerance, initial accuracy, temperature coefficient, voltage noise, and low voltage noise density
FactoryTest Conditions: Initial Accuracy ± /mv, Noise ±0.1Hz to 10 KHz) 15uV p-p, Voltage Noise Density = 50nVꢂsrt Hz, Temperature Coefficient
< 5ppmºC.
5) Phase noise measurements Fo = /0 MHz, other frequencies may vary by /0log Fꢂ/0MHz.
6) Typical start up time for the frequency range of 1/.8 MHz to /5 MHz <330 us.
7) Leave Pad 8 unconnected if enable ꢂ disable function is not required.When tri-stated, the output stage is disabled but the oscillator and compensation
circuit are still active ±current consumption < 1mA).
8) Additional pull ranges are available; please contact the factory for additional information.
9) For best performance it is recommended that the device connected to this output should have an equivalent input capacitance of 15pF.
10) Output is AC coupled.
11) For best performance it is recommended that the device connected to this output should have an equivalent input capacitance of 10pF.
