VCXO Functional Description
VCXO Feature: The VTM3 can be ordered with a VCXO function for applications where it will be used in a
PLL, or the output frequency needs fine tune adjustments. This is a high impedance input, 0.5 Mohm, 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 devices.
“No Adjust” Feature: In applications where the VTM3 will not be used in a PLL, or the output frequency
does not fine tune adjustments, the best device to use would be a VTM3-x0xx. By using the “no adjust”
option, the circuit is simplified as Vc does not need to adjusted or set to a predetermined voltage and pin
1 should be grounded (pin 1 can be left open but should not be set to a voltage such as the supply).

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 VTM3, 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.

Suggested IR profile
Devices are built using lead free epoxy and can also be subjected to standard lead free IR reflow
conditions, Table 7 shows max temperatures and lower temperatures can also be used e.g. peak
temperature of 220C.
