Description

Vectron’s VVC1/VVC2 Voltage Controlled

Crystal Oscillator (VCXO) is a quartz stabilized

square wave generator with a CMOS output and

is tested at CMOS and TTL (5.0 volt operation)

logic levels.

The VVC1/VVC2 uses fundamental crystals

resulting in low jitter performance and a

monolithic IC which improves reliability and

reduces cost.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional

operation is not implied at these or any other conditions in excess of conditions represented in the

operational sections of this data sheet. Exposure to absolute maximum ratings for extended periods may

adversely affect device reliability.

Handling Precautions

Although ESD protection circuitry has been designed into the the VVC1/VVC2, 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.

and higher pull can result in 20% linearity instead of 10%. Consult factory or your local sales representative with application

requirements.
