Description
The VS-550 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 J-lead surface mount package
offered on tape and reel. It has a frequency select function
that enables either “Frequency 1” or “Frequency 2.”

Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and
IR reflow simulation. The VS-550 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-550 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-550 device is
hermetically sealed so an aqueous wash is not an
issue.
