Crystal phase noise

WebLow-noise, Low-Power Crystal Oscillators. Renesas crystal oscillator devices are low-power crystal oscillators that can be used in standard 5mm x 7mm quartz oscillator footprints. The phase noise performance of the Renesas crystal oscillators enables their use as reference clocks for phase-noise sensitive applications. Webcrystal oscillator phase noise was –130 dBc/Hz at the 10 kHz offset. −130dBc/ Hz +33dB =−97dBc / Hz Therefore, measured at 10 kHz offset from the carrier, the multiplied phase noise contribution of a 20 MHz crystal that has a –130 dBc/Hz phase noise brings the total phase noise of a 920 MHz synthesizer PLL to –97 dBc/Hz.

This … Web•Phase Noise is a measurement of uncertainty in phase of a signal. It is measured as the ratio of noise power in quadrature (90°out of phase) with the carrier signal to the power of carrier signal. This is opposed to AM noise which is noise in phase with the carrier signal.
