TCXO: Initial calibration @ 25
C. Specifications at time of shipment after 48
hours of operation.
Inclusive of calibration @ 25
C, frequency vs. change in temperature, change in
supply voltage (±5%), load change (±5%), reflow soldering process and 20
years aging.
For best in applicationperformance, 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/sqrtHz, Temperature Coefficient < 5ppm°C.
Leave Pad 8 unconnected if enable / disable function is not required. When tri-
stated, the output stage is disabled but the oscillator and compensation circuit
are still active (currentconsumption <1 mA).
Additional pull ranges are available; please contact the factory for additional
information.
Output is AC coupled.
