The VS-750 is a SAW based voltage controlled oscillator that operates at the fundamental frequencies of the internal SAW filters. These SAW filters are high-Q quartz devices that enable the circuit to achieve low phase jitter performance over a wide operating temperature range. The dual oscillator is housed in a hermetically sealed leadless surface mount package offered on tape and reel. It has a frequency select function that enables either "Frequency 1" or "Frequency 2." It also has an output disable to facilitate on-board testing.

See Standard Frequencies and Ordering Information (Pg 7). Parameters are tested with production test circuit below (Fig 1). Parameters are tested at ambient temperature with test limits guardbanded for specified operating temperature. Measured as the maximum deviation from the best straight-line fit, per MIL-0-55310. Measured from 20% to 80% of a full output swing (Fig 2). Not tested in production, guaranteed by design, verified at qualification. Integrated across 50 kHz to 80 MHz, per GR-253-CORE Issue3. Tested with Vc = 0.3V to 3.0V.

Stresses in excess of these absolute maximum ratings can permanently damage the device. Also, exposure to these absolute maximum ratings for extended periods can adversely affect device reliability. Functional operation is not implied at these or any other conditions in excess of those represented in the operational sections of this datasheet. Permanent damage is also possible if any device input (Vc, FS, or OD) draws greater than 100 mA.

Reliability
Preliminary Data Sheet
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow simulation. The VS-750 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 2016
Handling Precautions
Although ESD protection circuitry has been designed into the VS-750 proper precautions should be taken when handling and mounting. VI employs a human body model (HBM) and a charged-device model (CDM) for ESD susceptibility testing and design protection evaluation.

Temperature (DegC)
The device has been 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. The temperatures refer to the topside of the package, measured on the package body surface. The VS-750 device is hermetically sealed so an aqueous wash is not an issue.
