VCTCXO products with
exceptional frequency
stability and low phase
noise. Through the use
of analog temperature
compensation, these products are capable
of holding Stratum 3 level temperature
stabilities of ±0.28 ppm over the commercial
and industrial temperature ranges. Available
in 4-pad or 10-pad surface mount footprints.
These products are designed for
such applications as IEEE 1588 PTP and
Synchronous Ethernet.
All models will meet ±4.6 ppm accuracies
for twenty years

BW = 12 KHz to 20 MHz
Leave Pad 8 on the T Series 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 (current consumption < 1 mA).
Attention: To achieve optimal frequency stability, and in some cases to meet the specification stated on this data sheet, it is required that the
circuit connected to this TCXO output must have the equivalent input capacitance that is specified 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.
Load components are required for proper operation of the device.
Output is AC coupled.
