Vectron International has introduced a series of surface
mount, Temperature Compensated Crystal Oscillators
(TCXOs) available in frequencies from 0.5 to 160 MHz.
Model Z5 surface mount TCXOs can be mounted
using the standard convection reflow process. The
units can meet the ±0.37 ppm Holdover requirement of
GR-1244-CORE Table 3-1 from 0ºC to +70ºC
temperature range and operate from a 3.3V or 5V
supply. Current drain to lower than 2 mA is available
upon request. Aging <3.5 ppm for ten years. Phase
noise is -115 dBc/Hz at 100 Hz and -155 dBc/Hz at
100k Hz at 10 MHz.
These units are ideal for Stratum 3 applications.

For this series TCXO typical current draw will be about 15 mA and
depending on output type may be less than 2 mA. Please consult the
factory about your exact current requirements.

Contact the factory for assistance.
For HCMOS / ACMOS / TTL & PECL
outputs with frequencies above 35 MHz
a low phase noise PLL multiplier may be
used. Please inform that factory of your
phase noise requirements.
Standard Frequencies: 10.00, 12.80, 16.384, 19.44, 20.00, 38.88, 40.00, 77.76, 155.52 MHz,
Available from 0.5 MHz to 160 MHz

Note: TCXOs are precision subsystems with tolerances measured to ±0.01 ppm. Non-Hermetically sealed TCXOs should
not be subjected to a wash process that will immerse the TCXO in solvents. NO CLEAN is the recommended procedure.
The Z5 series of TCXOs has been designed for pick and place reflow soldering. The suggested reflow profile is shown
above. The TCXO may be reflowed once, and should not be reflowed in the inverted position. Typical frequency shift as a
result of reflow is <1.0 ppm per reflow.
