See Standard Frequencies and Ordering Information (Pg 7). Parameters are tested with production test circuit below (Fig 1). 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. Measured from 20% to 80% of a full output swing (Fig 2). Not tested in production, guaranteed by design, verified at qualification. Integrated across stated bandwidth per GR-253-CORE Issue3. Aging Rate for 10 years (Aging is not part of overall frequency stability budget unless specified at time of order) Broadband Period Jitter measured using Lecroy Wavemaster 8600A 6 GHz Oscilloscope, 250K samples taken.

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. Permanent damage is also possible if OD is applied before Vcc.

Functional Test: Allows standard power supply configuration. Since AC coupled, the LV-PECL levels cannot be measured.
Production Test: Allows direct DC coupling into 50 measurement equipment. Must bias the power supplys as shown. Similar to Figure 1.

SO-720 SAW Clock Oscillator
Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow simulation. The SO-720 family is capable of meeting the following qualification tests:
Environmental Compliance
Parameter Mechanical Shock Mechanical Vibration Solderability Gross and Fine Leak Resistance to Solvents 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
Handling Precautions
Although ESD protection circuitry has been designed into the SO-720 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.
