PACKAGE CHARACTERISTICS
Package
Ceramic Surface Mount Package.
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 25C.
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
