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 Power Supply Voltage Control Range Storage Temperature Symbol VDD VC TS Ratings 0 to 6 0 to VDD -55 to 125 Unit V V °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 Mechanical Shock Mechanical Vibration Solderability Gross and Fine Leak Resistance to Solvents Moisture Sensitivity Conditions MIL-STD-883, Method 2002 MIL-STD-883, Method 2007 MIL-STD-883, Method 2003 MIL-STD-883, Method 1014 MIL-STD-883, Method 2015 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.
