Description
Vectron’s VCC4 Crystal Oscillator (XO) is quartz
stabilized square wave generator with a CMOS
output, operating off a 1.8, 2.5, 3.3 or 5.0 volt
supply.
The VCC4 uses fundamental or 3
rd
overtone
crystals for output frequencies > 50MHz resulting
in low jitter performance. VCC4 is hermetically
sealed and also uses a monolithic IC, which
improves reliability and reduces cost.

Enable/Disable Functional Description
Under normal operation the Enable/Disable is left open, or set to a logic high state, and the VCC4 is
oscillating. 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.

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

Handling Precautions
Although ESD protection circuitry has been designed into the the VCC4, 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 1500 JESD 22-C101
Suggested IR profile
Devices are built using lead free epoxy and can also be subjected to standard lead free IR reflow
conditions, Table 9 shows max temperatures and lower temperatures can also be used e.g. peak
temperature of 220C.
