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).

VI employs a Human Body Model and a Charged-Device Model (CDM) for ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on the circuit parameters used to define the model. Although no industry wide standard has been adopted for the CDM, a standard HBM of resistance = 1.5kohms and capacitance = 100pF is widely used and therefore can be used for comparison purposes.
