Default Silicon Labs 530 low jitter oscillator

Anybody any experience with this osc?

Reportedly it renders better results than Tent Clock..

I did. Very good.

Table 4. CLK± Output Phase Jitter
Phase Jitter (RMS) for FOUT of 10 to 160 MHz CMOS Output 12 kHz to 20 MHz (OC-48) 0.62 ps 50 kHz to 20 MHz 0.61 ps

Table 5. CLK± Output Period Jitter
Period Jitter* JPER RMS 2 ps
Peak-to-Peak 14 ps

While I haven't experimented with this device, I remain unimpressed with it's specifications for digital audio application. First, there is no phase noise plot shown, only a few cardinal point specs. Second, close-in phase noise is only given for carrier frequencies of 120MHz and above, and even then, not at a 10Hz offset. Third, at carrier frequencies useful for audio (10MHz rage), phase noise is only given down to a 12KHz offset.

So, is this a superior oscillator for digital audio purposes? Maybe, but I think that is not a fact established in the data sheet.

I plotted the phase noise (from the datasheet) for several oscillators including the silicon labs part:

H I F I D U I N O: Clock in Buffalo II DAC

The data is limited to what is available in the data sheets, but since the phase noise curve follows a known pattern, you could extrapolate...

the NEL does look llike the best so far

if you want to throw money at the non-problem then Vectron EMXO series evacuated SC cut with low vibration sensitivity may make more sense - they claim to be able to "significantly" better the -130 dB@100 Hz close in noise on request - but you'll probably have to pony up for a 100 piece min order

when human jitter perception in audio is looked for in DBT studies the sensitivity is absurdly low - 100s of nS - not ps
