OD
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.

Parameters are tested with production test circuit below (Fig 2).
Parameters are tested at ambient temperature with test limits guardbanded 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 1).
Not tested in production, guaranteed by design, verified at qualification.
Integrated across 12 kHz to 20 MHz, per GR-253-CORE Issue3.
Integrated across 50 kHz to 80 MHz, per GR-253-CORE Issue3.

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