VCXO Feature: The VT-501 can be ordered with a VCXO function for applications were it will be used in a PLL, or the output frequency
needs fine tune or calibration adjustments. This is a high impedance input , 1Mohm, 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 device.
“No Adjust” Option: In applications were the VT-501 will not be used in a PLL , or the output frequency does not need fine tune
adjustments, the best device to use would be a VT-501-xxx-xxx0. By using the “no adjust” option, the circuit is simplified as Vc does not
need to be adjusted or set to a predetermined voltage and pin 1 should be grounded (pin 1 can be left open but should not be set to a
voltage such as an RF signal or power supply voltage.
