1. A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.
2. Output is DC coupled.
3. Output is active if E/D is open.

VCXO Functional Description
VCXO Feature: The VTC2 can be ordered with a VCXO function for applications were it will be used in a
PLL, or the output frequency needs fine tune adjustments. This is high impedance, 1 Mohm, input 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 were the VTC2 will be not be used in a PLL, or the output frequency
does not fine tune adjustments, the best device to use would be a VTC2-x0xxx. 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 or left open (but not 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 VTC2, 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.
