VTC1 Data sheet
VCXO Functional Description
VCXO Feature:
The VTC1 can be ordered with a VCXO function for applications were 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 were the VTC1 will be 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.
