VS-505 Voltage Controlled Saw Oscillator (VCSO)
  Back to Product Table


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.
