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.
