Description
Vectron's VCC6-D Crystal Oscillator (XO) is quartz stabilized square wave generator with a LV-PECL or LVDS output, operating off a 3.3 volt supply. The VCC6 uses high quality on-chip multiplier to multiply a 26.5625 crystal to either 106M250 or 212M500.

1. A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended. 2. Figure 1 defines these parameters. Figure 2 illustrates the operating conditions under which these parameters are tested and specified. 3. Symmetry is measured defined as Vs, On Time/Period. 4. Includes calibration tolerance, operating temperature, supply voltage variations, aging (40 degreesC/10 years) and shock and vibration (not under operation). Aging budget is +/-5 ppm. 5. Output w ill be enabled if enable/disable is left open. Output frequency=106M250 if FREQ is left open.

VCC6-D, Dual Rate 106.250/212.500 LVPECL or LVDS XO 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. Exposure to absolute maximum ratings for extended periods may adversely affect device reliability. Table 2.

Reliability
The VCC6 qualification tests will include the following:

Parameter Mechanical Shock Mechanical Vibration Solderability Gross and Fine Leak Resistance to Solvents Conditions MIL-STD-883 Method 2002 MIL-STD-883 Method 2007 MIL-STD-883 Method 2003 MIL-STD-883 Method 1014 MIL-STD-883 Method 2016
Handling Precautions
Although ESD protection circuitry has been designed into the the VCC6, 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
The VCC6 has been qualified to meet the JEDEC standard for Pb-Free assembly. The temperatures and time intervals listed are based on the Pb-Free small body requirements and parameters are listed in Table 7. The VCC6 is hermetically sealed so an aqueous wash is not an issue.
