The PX–990 Crystal Oscillator (XO) offers ultra low phase noise performance with a phase noise floor below –175 dBc/Hz. The PX–990 is offered in a standard ruggedized enclosure with g–sensitivity below 0.5 ppb/g. With an available frequency range of 60 MHz to 120 MHz, the PX-990 is the perfect oscillator for mobile and land based radar applications. In addition to an ultra low noise phase noise floor, the PX–990 doesn't compromise on the close in phase noise performance. The PX–990 is capable of meeting –127 dBc/Hz at a 100 Hz offset at 120 MHz due to Vectron's unique SR–45 crystal. If you're operating in a harsh environment, your performance doesn't need to suffer. The PX–990 can be provided with shock absorbers minimizing the phase noise degradation in harsh operating environments.
