VCXO Functional Description
VCXO Feature: The VTC2 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 VTC2 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 VTC2-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).
