Description
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.
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.

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.
