156.26MHz-LVPECL-SPXO OCXO-LVCMOS/26.000MHz
   


Two chips with CMOS heater chip, the temperature control function, and the
frequency temperature correction function in SMD-PKG(7~5~1.8mm) are
installed.Oscillation IC@and Crystal is maintained to 90`100 with the heater.
The oscillation frequency within the range of the temperature of the quartz vibrator
is maintained and the frequency stability level is maintained by always making the
temperature of the oscillation substrate constant even if an environmental
temperature changes.
As for the quartz vibrator, the reliability of OCXO that the temperature change of
the repetition doesn't include the temperature change severely to reliability
becomes a good conditioD
There is not a possibility of the bit change of TCXO, and either it is steady
operation warrantable.
