Description

The VS-500 is a SAW based voltage controlled oscillator that
operates at the fundamental frequency of the internal SAW filter.
This resonator 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 J-lead surface mount package offered on tape and reel.
It has an output disable to facilitate on-board testing.

Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is
not implied at these or any other conditions in excess of conditions represented in the operational sections of this
datasheet. Exposure to absolute maximum ratings for extended periods may adversely affect device reliability.

Suggested Output Load Configurations (3.3V Operation)

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.

Functional Test: Allows standard power supply configuration.
Since AC coupled, the LV-PECL levels cannot be measured.

LV-PECL to LVDS: Restricted for short transmission lengths.

Configuration may require modification depending on LVDS receiver.

Reliability

The VS-500 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-500 proper precautions should be taken when
handling and mounting. VI employs a human body model and a charged-device model (CDM) for ESD
susceptibility testing and design protection evaluation.

ESD Ratings

Model Minimum Conditions

Human Body Model 1500 V MIL-STD 883, Method 3015
Charged Device Model 1000 V JESD 22-C101

Recommended Solder Reflow Profile

VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR
reflow simulation. The conditions a device can withstand are well understood and devices can be subjected to the
profile above. This profile shows a ramp up condition to prevent thermal shock, a preheat period in which the flux
is activated, a ramp up to 183°C which is the reflow temperature of Sn/Pb eutectic, and a gradual cool down. The
time above 183°C should not exceed 60 seconds and the peak temperature should be no more than 220°C for 10
seconds. The VS-500’s are hermetically sealed so an aqueous wash is not an issue.
