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).
