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 defined as Vs, On Time/Period.
4. Includes calibration tolerance, operating temperature, supply voltage variations, aging (10 years @ 40 degreesC) and shock
and vibration (not under operation).
5. Output will be enabled if enable/disable is left open.
6. Jitter is measured using a LeCroy8600 sampling 50,000 cycles.

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.

Model Minimum Conditions
Human Body Model 1000 MIL-STD-883 Method 3115
Charged Device Model 1000 JESD 22-C101
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 5.
As the contact pads are gold over nickel, devices can be reflowed at lower temperatures. The VCC6 is
hermetically sealed so an aqueous wash is not an issue.
