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 Soldering Temp/Time Symbol VCC VC TS TLS Ratings 0 to 6 0 to VCC -55 to 125 240/10 Unit V V C C/sec
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 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
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.
ESD Ratings
Model Human Body Model Charged Device Model Minimum 500 500 Conditions MIL-STD 883, Method 3015 JESD 22-C101
Recommended Solder Reflow Profile
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 183C which is the reflow temperature of Sn/Pb eutectic, and a gradual cool down. The time above 183C should not exceed 60 seconds and the peak temperature should be no more than 220C for 10 seconds. The VC-710's are hermetically sealed so an aqueous wash is not an issue.
