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.
