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.
Features
Industry Standard Package, 5.0 x 7.5 x 2.5 mm
Output Frequencies from 500 MHz to 850 MHz
3.3 V Operation
Applications
PLL circuits for clock smoothing and frequency translation

Stresses in excess of the absolute maximum ratings can permanently damage the device. 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.

Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow
simulation. The VS-700 family is capable of meeting the following qualification tests:

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