VS-700 Voltage Controlled SAW Oscillator VS-700 Description The VS-700 is a SAW based voltage controlled oscillator that operates at the fundamental frequency of the internal SAW filter. The SAW filter 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 a hermetically sealed leadless surface mount package offered on tape and reel. It has an output disable to facilitate on-board testing.

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 Issue4. Tested with Vc = 0.3V to 3.0V.

Also, exposure to these absolute maximum ratings for extended periods may 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 or OD) draws >100 mA. Suggested Output Load Configuration LV-PECL to LV-PECL: For short transmission lengths, the power consumption could be reduced by removing the 100Ω resistor and doubling the value of the pull down resistors. LV-PECL to LVDS: Restricted for short transmission lengths. Configuration may require modification depending on LVDS receiver. Functional Test: Allows standard power supply configuration. Since AC coupled, the LV-PECL levels cannot be measured. Production Test: Allows direct DC coupling into 50Ω measurement equipment. Must bias the power supplys as shown. Similiar to figure 1.

The VS-700 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 2016 Handling Precautions Although ESD protection circuitry has been designed into the VS-700 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.

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-700 device is hermetically sealed so an aqueous wash is not an issue.
