Description
Vectron's VCS3 Crystal Oscillator (XO) is quartz stabilized square wave generator with a CMOS output, operating from a 1.8, 2.5 or 3.3 volt supply. The VCS3 utilized a high performance, low frequency quartz resonator followed by a custom ASIC to synthesize the output frequency.

VCS3 Data Sheet
Enable/Disable Functional Description
Under normal operation the Enable/Disable is left open or set to a logic high state. 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.

Reliability
The VCS3 qualification tests have included: Table 5. Environnemental Compliance
Parameter Mechanical Shock Mechanical Vibration Temperature Cycle Solderability Gross and Fine Leak Resistance to Solvents MSL MIL-STD-883 MIL-STD-883 MIL-STD-883 MIL-STD-883 MIL-STD-883 MIL-STD-883 1 Conditions Method 2022 Method 2007 Method 1010 Method 2003 Method 1014 Method 2015
Handling Precautions
Although ESD protection circuitry has been designed into the the VCS3, 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.

Suggested IR profile
Devices are built using lead free epoxy and can also be subjected to standard lead free IR reflow conditions, Table 9 shows max temperatures and lower temperatures can also be used e.g. peak temperature of 220C. Table 7. Reflow Profile (IPC/JEDEC J-STD-020) Parameter Symbol
