OCXO’ (Oven Controlled Crystal
s
Oscillators) are used when frequency vs.
temperature requirements are too stringent to
be met by a basic XO (Crystal Oscillator) or
TCXO (Temperature Compensated Crystal
Oscillator). With an OCXO, the temperature
of the crystal and critical circuits are kept
constant as the temperature outside the
oscillator varies. Controlling the temperature
inside the oscillator with an oven maintains
this constant temperature. In an OCXO, the
changes in the ambient temperature are
sensed and then fed back to an oven control
that continually maintains a constant optimum
temperature inside the oscillator enclosure.
An OCXO can improve the crystal's inherent
stability by more than 5000 times. The
oven control system is not perfect, the open
loop gain is not infinite, there are internal
temperature gradients inside the oven
(oscillator) and, in a conventional oven, the
circuitry outside the oven shell is subjected to
ambient temperature changes that can "pull"
the frequency.
The improved temperature stability
performance of a conventional OCXO over an
XO or TCXO comes at a steep price. OCXO
power consumption, for instance, is greater
by a factor of over 200. There is also a size
consideration. In an ordinary OCXO, a
crystal is enclosed in a metal case which is
then placed inside an oven shell together with
temperature sensitive circuitry, and then
