Description
The VS-500 is a SAW based voltage controlled oscillator that
operates at the fundamental frequency of the internal SAW filter.
This resonator is a high Q quartz device that enables the circuit
to achieve low phase jitter performance over a wide operating
temperature range. The oscillator is housed in a hermetically
sealed J-lead surface mount package offered on tape and reel.
It has an output disable to facilitate on-board testing.

1. See Standard Frequencies and Ordering Information (Pg 8).
2. Parameters are tested with production test circuit below (Fig 2).
3. Parameters are tested at ambient temperature with test limits guardbanded for specified operating temperature.
4. Measured as the maximum deviation from the best straight-line fit, per MIL-0-55310.
5. 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, per GR-253-CORE Issue3.
8. Integrated across 50 kHz to 80 MHz, per GR-253-CORE Issue3.
9. Tested with Vc = 0.3V to 3.0V.

Test Circuit Notes:
1) To Permit 50Measurement of Outputs, all DC Inputs are Biased Down 1.3V.
2) All Voltage Sources Contain Bypass Capacitors to Minimize Supply Noise.
3) 50Terminations are Within Test Equipment.
