Description
The VS-505 is a Voltage Controlled SAW 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. A divider circuit is deployed for
output frequencies less than 491.52 MHz. The oscillator is
housed in a hermetically sealed leadless surface mount
package and offered on tape and reel. It has a tri-state Output
Select function that provides one of three conditions: Output
Disable, Output Set, or Output Enable.

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 OS) draws >100 mA.

LV-PECL to LV-PECL: For short transmission lengths, the pull
down resistor values shown provide reasonable power
consumption and waveform performance.
Functional Test: Allows use of standard power supply biasing
configuration. Pull down resistors are used for LV-PECL outputs
and are removed for with LVDS outputs. Since the LVDS outputs
are AC coupled, the output DC levels cannot be measured.
LVDS to LVDS: The 100Ω resistor should be removed if this load is
provided internally within the LVDS receiver.

Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and
IR reflow simulation. The VS-505 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
Moisture Sensitivity Level IPC/JEDEC J-STD-020, MSL1
Handling Precautions
Although ESD protection circuitry has been designed into the VS-505 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 VS-505 is 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-505 should not be subjected to a
wash process that will immerse it in solvents. NO
CLEAN is the recommended procedure. The VS-505
has been designed for pick and place reflow soldering.
The VS-505 may be reflowed once and should not be
reflowed in the inverted position.
