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.
Contact Pads are gold over nickel
