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.
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.
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.

As the oscillator ages, relaxation of the crystal mounting stress
or transfer of environmental stress through the package to the
crystal mounting arrangement can lead to frequency variations.
VTI has minimized these two effects through the use of a
miniature AT-Cut strip resonator crystal which allows a
superior mounting arrangement and results in minimal
relaxation and almost negligible environmental stress transfer.
Mass-loading on the crystal generally results in a frequency
decrease and is typically due to out-gassing of material within a
hermetic package or from contamination by external material in
a less than hermetic package. VTI has minimized the impact
of mass loading by ensuring hermetic integrity and minimizing
out-gassing by limiting the number of internal components
through the use of ASIC technology.
Under normal operating conditions with an operating
temperature of 40°C, the J-Type will typically exhibit 2 ppm
aging in the first year of operation. The device will then
typically exhibit 1 ppm aging the following year with a
logarithmic decline each year thereafter.
Handling Precautions
Although protection circuitry has been designed into this
device, proper precautions should be taken to avoid exposure
to electrostatic discharge (ESD) during handling and mounting.
VTI employs a human-body model (HBM) and a charged-
device model (CDM) for ESD-susceptibility testing and
protection design evaluation.
ESD voltage thresholds are dependent on the circuit
parameters used to define the mode. Although no industry-
wide standard has been adopted for the CDM, a standard HBM
(resistance = 1500Ω, capacitance = 100pF) is widely used and
therefore can be used for comparison purposes. The HBM
ESD threshold presented here was obtained by using these
circuit parameters.
