Description
The VC-700 is a voltage controlled crystal oscillator that
operates at the fundamental frequency of the internal HFF
crystal. The HFF crystal is a high-Q quartz device that
enables the circuit to achieve low phase jitter performance
over a wide operating temperature range. The oscillator is
housed in an industry standard hermetically sealed leadless
surface mount package and is available on tape and reel.

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 VC-700 family is capable of meeting the following qualification tests:
Environmental Compliance

Mechanical Shock
Mechanical Vibration
Solderability
MIL-STD-883, Method 2002

MIL-STD-883, Method 2015
Gross and Fine Leak
Resistance to Solvents
Handling Precautions
Although ESD protection circuitry has been designed into the VC-700 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.

VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow
simulation. The conditions a device can withstand are well understood and devices can be subjected to the profile above. This
profile shows a ramp up condition to prevent thermal shock, a preheat period in which the flux is activated, a ramp up to 183˚C
which is the reflow temperature of Sn/Pb eutectic, and a gradual cool down. The time above 183˚C should not exceed 60
seconds and the peak temperature should be no more than 220˚C for 10 seconds. The VC-700’s are hermetically sealed so
an aqueous wash is not an issue.
