Pink Faun Ultra OCXO
The Pink Faun Ultra OCXO Clock is especially designed for use in high-end audio and music servers. Our OCXOs are available in various audio frequencies and can also be used for upgrading the standard oscillators on motherboards. Common frequencies used on motherboards are 24 and 25 MHz oscillators. Normally, OCXOs with these frequencies have a considerably higher phase noise just by function of their higher frequency (compared to 10M XO’s). But not with our Ultra OCXO Clock: the typical phase noise of the Pink Faun Ultra OCXO Clock is < -130 dB @ 10 Hz offset from the carrier (i.e. 24 or 25 MHz). Every Pink Faun Ultra OCXO is square wave out and thus quite suitable for direct connection, without the need for a multiplier circuit to reach the correct frequency (which will also increase phase noise).
Available frequencies: 20 MHz / 22.569 MHz / 24 MHz / 24.576 MHz / 25 MHz
Phase noise and Jitter of clocks
In the simplest terms, phase noise describes the stability of an oscillator in the Frequency Domain while jitter describes stability in the Time Domain.
Because the jitter is much smaller than one complete period (see graph), we can say it is caused by 'Phase Fluctuations' (instead of frequency fluctuations). Since these fluctuations are noise, it's actually phase noise.
During the development of the Pink Faun Ultra OCXO clock, we focused on reduction of jitter. Using high Q crystal material for the Ultra-low noise OCXO and special circuitry to reduce noise in the oscillator.
They are two methods of looking at the same parameter: phase noise looks at the signal spectrum, i.e. in the frequency domain, whereas phase jitter looks at the variations of phase upon the signal. Phase noise characterizes the shape of the frequency spectrum of the oscillator.
The term phase noise is used to describe the noise spectrum resulting from phase jitter that arises as a result of random phase variations of the signal. The noise arises from general noise in the circuit that manifests itself as phase jitter. Since phase and frequency are inextricably linked, this can also be seen as random frequency variations. In high-end audio, the phase noise is incredibly important because phase noise reduces the signal quality and hence increases the error rate of the communications link.
