3.2x5.0mm Temperature
Compensated Crystal Oscillators and
Voltage Controlled Temperature
Compensated Crystal Oscillators are
designed for use in applications
requiring tight frequency stability in a
small package. Through the use of
Analog Temperature Compensation,
this device is capable of holding sub
1-ppm stabilities over wide
temperature ranges.

Note:
1) TCXO: Initial calibration @ 25°C. Specifications at time of shipment after 48 hours of
operation.
2) Frequency change after reciprocal temperature ramped over the operating range.
Frequency measured before and after at 25ºC.
3) Within two hours after reflow.
4) For best in application performance, careful selection of an external power source is
critical. Select an external regulator that meets or exceeds to following specifications
regarding voltage regulation tolerance, initial accuracy, temperature coefficient, voltage
noise, and low voltage noise density.
Factory Test Conditions:
Initial Accuracy ±2mv,
Noise (0.1Hz to 10 KHz) 15uV p-p, Voltage Noise Density = 50nV/sqrt Hz, Temperature
Coefficient < 5ppm/°C.
5) Output is DC coupled
