VCXO Functional Description
VCXO Feature: The VTC1 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, 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 where the VTC1 will not be used in a PLL, or the output frequency
does not fine tune adjustments, the best device to use would be a VTC1-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).

NOTE: Additional pads are used to program and adjust the TCXO during manufacturing and should be
left open; do not terminate these to the supply voltage. Some designs do not include these additional
pads. It’s recommended to not have traces routed underneath the devices.
