The VI S-Type Voltage Controlled Crystal

Oscillator (VCXO) is a quartz stabilized square

wave generator with a CMOS output and is

tested at CMOS (3.3 and 5V operation) and TTL

(5 V operation) logic levels. Devices are tested

for absolute pull range (APR) and start-up over

the operating temperature range which insures

the performance and reliability.

Handling Precautions

Although ESD protection circuitrry has been designed into the the S-Type, proper precautions should be

taken when handling and mounting. VI employs a human body model and a charged-device model (CDM)

for ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on the

circuit parameters used to define the model. Although no industry wide standard has been adopted for the

CDM, a standard HBM of resistance=1.5Kohms and capacitance = 100pF is widely used and Therefore

can be used for comparison purposes.

Absolute Pull Range (APR) Specification

The frequency deviation of the S-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.

An S-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 see Vectron’s web site,

www.vectron.com,

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. VI 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.
