Description
SAW 1
SAW 2
The VS-750 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 leadless surface mount
package offered on tape and reel. It has a frequency select
function that enables either “Frequency 1” or “Frequency 2.” It
also has an output disable to facilitate on-board testing.

Stresses in excess of these absolute maximum ratings can permanently damage the device. Also, exposure to
these absolute maximum ratings for extended periods can 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, FS, or OD) draws
greater than 100 mA.

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.

Handling Precautions
Although ESD protection circuitry has been designed into the VS-750 proper precautions should be taken when
handling and mounting. VI employs a human body model (HBM) and a man man model (MM) 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-750 device is
hermetically sealed so an aqueous wash is not an
issue.
