A J-Type VCXO with an APR of +/-50 ppm will track a +/-50
ppm reference source over all operating conditions. The
same device will typically demonstrate a Total Pull
capability of 150 to 350 ppm.
Absolute Pull Range (APR) is
specified by the fourth character of the product code in Table
6.
Please contact VTI for the APR Application Note.
Absolute Pull Range (APR) Specification
The frequency deviation of the J-Type VCXO is specified in
terms of Absolute Pull Range (APR). APR provides the user
with a guaranteed specification for minimum available
frequency deviation over all operating conditions. Operating
conditions include operating temperature range, power supply
variation, differences in output loading and changes due to
aging.
Oscillator Aging
Quartz stabilized oscillators typically exhibit a small shift in
output frequency during aging. The major factors which lead to
this shift are changes in the mechanical stress on the crystal
and mass-loading of foreign material on the crystal.
