Description
The VS-705 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.

1. See Standard Frequencies and Ordering Information (Pg 8).
2. Parameters are tested with production test circuit (Pg 3).
3. Parameters are tested at ambient temperature with test limits guard-banded for specified operating temperature.
4. Measured as the maximum deviation from the best straight-line fit, per MIL-0-55310.
5. The Vc Model is described below (Fig 1).
6. Parameters are described with waveform diagram below (Fig 2).
7. Not tested in production, guaranteed by design, verified at qualification.
8. For Frequencies >491.52 MHz, Jitter is Integrated across 50 kHz to 80 MHz.
For Frequencies <491.52 MHz, Jitter is Integrated across 12 kHz to 20 MHz. (Both per GR-253-CORE Issue3).
9. Tested with Vc = 0.3V to 3.0V.

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 100 resistor should be removed if this load is
provided internally within the LVDS receiver.

Although ESD protection circuitry has been designed into the VS-705 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-705 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-705 device is hermetically sealed so an
aqueous wash is not an issue.
