Description
The VS-505 is a Voltage Controlled SAW Oscillator that
operates at the fundamental frequency of the internal SAW
filter. The SAW filter is a high-Q Quartz device that enables the
circuit to achieve low phase jitter performance over a wide
operating temperature range. A divider circuit is deployed for
output frequencies less than 491.52 MHz. The oscillator is
housed in a hermetically sealed leadless surface mount
package and offered on tape and reel. It has a tri-state Output
Select function that provides one of three conditions: Output
Disable, Output Set, or Output Enable.
