Description
The SO-502 is a SAW based clock oscillator that operates at the fundamental frequency of the internal SAW resonator. This direct approach enables this series to achieve low phase noise and jitter performance at high output frequencies and over wide operating temperature range. The oscillator is housed in a hermetically sealed J-lead surface mount package offered on tape and reel. As an option, it has an output disable to facilitate on-board testing.

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.

Handling Precautions
Although ESD protection circuitry has been designed into the SO-502 proper precautions should be taken when handling and mounting. VI employs a human body model and a charged-device model (CDM) for ESD susceptibility testing and design protection evaluation.

Time (s)
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow simulation. The conditions a device can withstand are well understood and devices can be subjected to the profile above. This profile shows a ramp up condition to prevent thermal shock, a preheat period in which the flux is activated, a ramp up to 183C which is the reflow temperature of Sn/Pb eutectic, and a gradual cool down. The time above 183C should not exceed 60 seconds and the peak temperature should be no more than 220C for 10 seconds. The SO-502's are hermetically sealed so an aqueous wash is not an issue.
