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.

Table Notes:
1. See Standard Frequencies and Ordering Information
2. Parameters are tested with production test circuit
3. Parameters are tested at ambient temperature with test limits guard-banded for specified operating temperature.
4. Output levels are standard 100K PECL compatible and measured from 20% to 80% of a full output swing (Fig 1).
5. Not tested in production, guaranteed by design, verified at qualification.
6. Integrated across 12 kHz to 20 MHz or 50 kHz to 80 MHz per GR-253-CORE Issue3.
7. Maximum Frequency occurs at room temperature
