The VCA1 uses fundamental or 3rd overtone crystals, for output frequencies < 80MHz, resulting in low jitter performance, typically 0.5ps rms in the 12 kHz to 20MHz band.

When the E/D is set to a logic low, the oscillator stops and the output is in a high impedance state. This helps reduce power consumption as well as facilitating board testing and troubleshooting. Tri-state Functional Description Under normal operation the tri-state is left open or set to a logic high state. When the tri-state is set to a logic low, the oscillator remains active but the output buffer is in a high impedance state. This helps facilitate board testing and troubleshooting. Table 3.

Environnemental Compliance Parameter Mechanical Shock Mechanical Vibration Temperature Cycle Gross and Fine Leak Resistance to Solvents MIL-STD-883 MIL-STD-883 MIL-STD-883 MIL-STD-883 MIL-STD-883 Conditions Method 2022 Method 2007 Method 1010 Method 1014 Method 2015 Handling Precautions Although ESD protection circuitry has been designed into the the VCA1, proper precautions should be taken when handling and mounting. 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. Table 5. ESD Ratings Model Human Body Model Charged Device Model Minimum 1000 1500 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 6 shows max temperatures and lower temperatures. A peak temperature of 240°C minimum should be used to reflow the lead solder. Table 6.
