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.

1. A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.  
2. Figure 1 defines these parameters. Figure 2 illustrates the equivalent five gate TTL load and operating conditions under which  
these parameters are tested and specified.  
3. Symmetry is defined as (ON TIME/PERIOD with Vs= 1.4 V for TTL and Vs=2.5 V for CMOS, 5 volt operation, and Vs=1.65V

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.

NOTE: Not all combinations of options are available. Higher frequencies have less pull capability, especially at +3.3 volts supply,  
and higher pull can result in 20% linearity instead of 10%. Consult factory or your local sales representative with application  
requirements.
