VS-705
Single Frequency VCSO
VS-705
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.

Operating Temperature
TOP
See Standard Frequencies and Ordering Information (Pg 8). Parameters are tested with production test circuit (Pg 3). Parameters are tested at ambient temperature with test limits guard-banded for specified operating temperature. Measured as the maximum deviation from the best straight-line fit, per MIL-0-55310. The Vc Model is described below (Fig 1). Parameters are described with waveform diagram below (Fig 2). Not tested in production, guaranteed by design, verified at qualification. For Frequencies >491.52 MHz, Jitter is Integrated across 50 kHz to 80 MHz. For Frequencies <425.00 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.
Test Circuits & Output Load Configuration
Functional Test: Allows use of standard power supply biasing configuration. Pull down resistors are used for LV-PECL outputs and are removed for LVDS outputs. Since the LVDS outputs are AC coupled, the output DC levels cannots be measured.
Production Test: DC levels shown for VEE, OSelect, & Vc are for devices configured for 3.3V operation. LV-PECL outputs are DC coupled to 50Ω test equipment. LVDS outputs are connected to a digital volt meter, then AC coupled to the test equipment. The digital volt meter allows for Mid Level & Swing measurements.
LV-PECL to LV-PECL: For short transmission lengths, the pull down resistor values shown provide reasonable power consumption and waveform performance.
LVDS to LVDS: The 100Ω resistor should be removed if this load is provided internally within the LVDS receiver.

Handling Precautions
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. ESD Ratings Model

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-705 device is hermetically sealed so an aqueous wash is not an issue.
