Vectron’s VVC1 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.  
Input  
Buffer  
The VVC1 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, 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.

application requirements.
