Description
Vectron’s VCC1 Crystal Oscillator (XO) is quartz stabilized square wave generator with a CMOS output, operating off either a 1.8, 2.5, 3.3 or a 5.0 volt supply.
fo
Output Buffer / Disable
The VCC1 is uses fundamental or 3rd overtone crystals resulting in low jitter performance, typically 0.5pS rms in the 12 kHz to 20MHz band. Also a monolithic IC, which improves reliability and reduces cost, is hermitically sealed.

VCC1 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.
TriState Functional Description
Under normal operation the Tristate 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.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is not implied at these or any other conditions in excess of conditions represented in the operational sections of this data sheet.

Reliability
The VCC1 qualification tests have included:
Table 7. Environnemental Compliance

Handling Precautions
Although ESD protection circuitry has been designed into the the VCC1, 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.
