Description

Vectron’s VCC6 Crystal Oscillator (XO) is quartz

stabilized square wave generator with a LVDS

output, operating off a 2.5 or 3.3 volt supply.

The VCC6 uses a 3rd overtone crystals for output

frequencies < 200MHz resulting in low jitter

performance, typically 0.3pS rms in the 12 kHz to

20MHz band.

Enable/Disable Functional Description

Under normal operation the Enable/Disable is left open, or set to a logic high state, the VCC6 is an

oscillation mode and outputs are active. When the E/D is set to a logic low, the oscillator stops and the

both the output and complementary outputs are in a high impedance state. This helps facilitate board

testing and troubleshooting.

Power Saving Pull-Up Resistor

The E/D pull-up resistor changes in response to the input logic level; the pull-up resistor is a large value

when E/D is set to a logic low, which reduces the current consumed. When E/D is open, or set to a logic

high, the pull-up resistance becomes a smaller value which helps decrease the effects of external noise.

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.

Reliability

The VCC6 qualification tests include the following:

Table 6. Environnemental Compliance

Parameter Conditions

Mechanical Shock MIL-STD-883 Method 2002

Mechanical Vibration MIL-STD-883 Method 2007

Solderability MIL-STD-883 Method 2003

Gross and Fine Leak MIL-STD-883 Method 1014

Resistance to Solvents 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.
