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-701 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-701-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. S Maximum Ratings Absolute Maximum Ratings and Handling Precautions Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is not implied or any other excess of conditions represented in the operational sections of this data sheet. Exposure to absolute maximum ratings for extended periods may adversely affect device reliability. Although ESD protection circuitry has been designed into the VT-701, proper precautions should be taken when handling and mounting, VI employs a Human Body Model and Charged Device Model for ESD susceptibility testing and design evaluation. ESD thresholds are dependent on the circuit parameters used to define the model. Although no industry standard has been adopted for Phase of Noise Graph the CDM a standard resistance of 1.5kOhms and capacitance 100pF is widely used and therefor can be used for comparison purposes.
