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 for 3.3 Volt operation. 4. Only available as 50 ppm APR.

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.

Reliability
The VVC1/VVC2 is capable of meeting the following qualification tests.

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.
