Description
The VS-502 is a SAW based voltage controlled 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 test

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. Measured as the maximum deviation from the best straight-line fit, per MIL-0-55310.
5. Output levels are standard 100K PECL compatible and measured from 20% to 80% of a full output swing (Fig 1).
6. Not tested in production, guaranteed by design, verified at qualification.
7. Integrated across 12 kHz to 20 MHz, or 50 KHz to 80 MHz per GR-253-CORE Issue3.
8. Tested with Vc = 0.3V to 3V for 3.3V supply, Vc = 0.5V to 4.5 V for 5V supply, Vc = 0.5V to 11.5V for 12V supply
9. Maximum frequency occurs at room temperature
