Description
The VC-710 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.

Absolute Maximum Ratings
Parameter Symbol Ratings Unit
Power Supply VDD 0 to 6 V
Voltage Control Range VC 0 to VDD V
Storage Temperature TS -55 to 125 °C
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-710 family is capable of meeting the following qualification tests:
Environmental 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 2015
Moisture Sensitivity MSL1
Handling Precautions
Although ESD protection circuitry has been designed into the VC-710 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.

Suggested IR profile
The VC-710 is 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 the table below.
The contact pads are gold over nickel so lower IR reflow temperatures such as 220°C can be used (device is
backwards compatible with a lead solder assembly).
The VC-710 is hermetically sealed so an aqueous wash is not an issue.
