Working Principle

The DSC557-0344SE1 oscillator utilizes a Van-der-Waal force-based crystal resonator in order to function. In this arrangement, the crystal resonator is isolated from external mechanical and magnetic fields and is maintained at a constant temperature through the use of a heat sink. The oscillator further isolates the crystal resonator from surrounding electronics by placing it in a sealed enclosure.

The crystal resonator then vibrates at a frequency dependent on its mass and composition. This vibration induces an electrical current in the oscillator circuits which is used to drive the frequency of the oscillator. A precision reference temperature is also applied to the oscillator in order to measure and adjust the frequency independent of temperature fluctuation.

Performance Characteristics

The DSC557-0344SE1 oscillator is designed to provide an excellent performance in the following areas:

• Frequency accuracy: +/-0.5ppm or better over a temperature range of 0 to 70 degrees Celsius
• Frequency stability: +/-1ppm or better over an extended temperature range
• Jitter: as low as 1psec RMS
• Rise and fall times: as fast as 250psec
• Aging: negligible thermal aging

The DSC557-0344SE1 oscillator is a versatile and reliable frequency reference for many applications that require precision. Its tight frequency tolerances, low jitter level, and excellent temperature stability make it a perfect choice for a variety of precision frequency reference applications.
