VCXO Functional Description

VCXO Feature: The VTD3 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 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 devices.

“No Adjust” Feature: In applications where the VTD3 will not be used in a PLL, or the output frequency

does not need fine tune adjustments, the fixed TCXO/VTD3-x0xx is the best option. By using the “no

adjust” option, the circuit is simplified as Vc does not need to adjusted or set to a predetermined voltage.

Pin 1 can be grounded to reduce the risk of adding noise into the circuit.

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 VTD3, proper precautions should be taken

when handling and mounting. VI employs a Human Body Model and a Charged-Device Model (CDM) for

VTD3 Data Sheet

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

Table 7 shows max temperatures and lower peak temperatures can also be used e.g. peak temperature

of 230-240°C. The VTD3 should not be subjected to a wash process that will immerse it in solvents – a

no clean process is recommended.
