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.

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 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. T able 7.
