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.

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 <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.

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.
V DMV Production Test: DC levels shown for Vee, OSelect, & Vc are for devices configured for 3.3V operation. Vee LV-PECL outputs are DC coupled to 50 test equipment. LVDS outputs are connected to a digital volt meter, then AC coupled to the test equipment. The digitial 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 100 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 Mechanical Shock Mechanical Vibration Solderability Gross and Fine Leak Resistance to Solvents Moisture Sensitivity Level Conditions MIL-STD-883, Method 2002 MIL-STD-883, Method 2007 MIL-STD-883, Method 2003 MIL-STD-883, Method 1014 MIL-STD-883, Method 2016 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.
