Description
Vectron’s VCC6 Crystal Oscillator (XO) is quartz
stabilized square wave generator with a LV-PECL
output, operating off a 3.3 volt supply.
The VCC6 is uses 3rd overtone crystals for
frequencies under 200MHz, resulting in low jitter
performance, typically 0.5pS rms in the 12 kHz to
20MHz band.

VCC6-Q/R Series, 2.5 and 3.3v PECL Crystal Oscillator
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 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.

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.
