Clipped Sine Wave Output VCXO Functional Description VCXO Feature: The VTM3 can be ordered with a VCXO function for applications where it will be used in a PLL, or the output frequency needs fine tune adjustments. This is a high impedance input, 0.5 Mohm, 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 where the VTM3 will not be used in a PLL, or the output frequency does not fine tune adjustments, the best device to use would be a VTM3-x0xx. 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 (pin 1 can be left open but should not be 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.

ESD Ratings Model Human Body Model Charged Device Model Minimum 1000 1000 Conditions MIL-STD-883 Method 3115 JESD 22-C101 Suggested IR profile Devices are built using lead free epoxy and can also be subjected to standard lead free IR reflow conditions, Table 7 shows max temperatures and lower temperatures can also be used e.g. peak temperature of 220C.
