VTC4 series

The VTC4 series is designed as one kind of voltage controlled temperature compensated crystal oscillator with some features:(1)hermetically sealed ceramic SMD package;(2)gold over nickel contact pads;(3)optional VCXO function available;(4)fundamental crystal design;(5)output frequencies to 27 MHz;(6)clipped sine wave output;(7)product is compliant to RoHS directive and fully compatible with lead free assembly.It can be used in wireless communications,base stations,point to point radios,broadband access,test equipment and handsets.Vectron's VTC4 temperature compensated crystal oscillator (TCXO) is a quartz stabilized,clipped sine wave output, temperature compensated oscillator, operating off either 2.8,3.0, 3.3 or 5.0 volt supply.

Stresses in excess of the absolute maximum ratings can permanently damage the VTC4 series. 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.Although ESD protection circuitry has been designed into the the VTC4, 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.
