VCXO Function
S
3
VCXO Feature: The VT-803 is supplied with a VCXO function for applications were it will be used in a PLL, or the output frequency needs
fine tune or calibration adjustments. This is a high impedance input , 100 Kohm, and can be driven with an op-amp or terminated with
adjustable resistors etc. Pin 1 should not be left floating on the VCXO optional device.
Maximum Ratings
S
Absolute Maximum Ratings and Handling Precautions
Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is not implied or any other
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 VT-803, proper precautions should be taken when handling and mounting,
VI employs a Human Body Model and Charged Device Model for ESD susceptibility testing and design evaluation.
ESD thresholds are dependent on the circuit parameters used to define the model. Although no industry standard has been adopted for
the CDM a standard resistance of 1.5kOhms and capacitance of 100pF is widely used and therefor can be used for comparison purposes.

Suggested IR Profile
Devices are built using lead free epoxy and can be subjected to standard lead free IR reflow conditions shown in Table 5. Contact pads are
gold over nickel and lower maximum temperatures can also be used, such as 220°C.
