SAW Oscillator

Surface Acoustic Wave (SAW) oscillators are a category of oscillators utilizing a SAW resonator, SAW delay line, or SAW filter to stabilize or control its output frequency. SAW oscillators can be designed to oscillate directly up to several GHz. This is in contrast to Bulk Acoustic Wave (BAW) oscillators utilizing quartz crystals that can only be made to oscillate directly to about 700 MHz. Hence, the SAW has the advantage of higher frequency of oscillation over its quartz crystal resonator counterpart.

SAW oscillators construction

SAW oscillators by their physical construction are more robust (less fragile) then quartz crystal oscillators. They are also less sensitive to mechanical vibration which makes them the perfect choice for avionics applications.

SAW oscillators can be designed for fixed frequency operation or frequency pullable versions know as Voltage Controlled Saw Oscillators (VCSOs).
Phase locking a VCSO with a low frequency quartz based reference makes for an excellent combination for the generation of high frequency signals.

CRYSTEK LAUNCHES NEW 1GHz

Closed | July 21st, 2010 | Posted in saw oscillator
saw oscillatorFort Myers, FL, April 2008 – Crystek Crystals announces the release of a 1GHz SAW Clock Oscillator (CCSO). Crystek designed the module using FR5 PCB and SAW (surface acoustic wave) crystal technology to provide a low noise, low jitter performance with true SineWave output. The resulting oscillator features -142dBc/Hz phase noise at 10KHz offset.

Model number CCSO-914X3-1000 comes in a 9x14mm SMT package. It uses a +3.3V supply and generates a true-sinewave with +5dBm min. output power. The new CCSO has no sub-harmonics; second harmonic is -25dBc typical. The CCSO-914X3-1000 operates from -40C to +85C.

Applications include: system clock for network clock generator/synchronizer; clock for DDS; test and measurement; avionics; point-to-point radios; and multi-point radios.
