Best Value DAC Clock?

[drizdraz]

I'm rolling my own home DAC (trying ESS, AKM, TI). I want a really low-jitter clock environment, something in the femto-second spec range. The Crystek CCHD-957 ($25 ea) is very popular, but derives to audio performance in the low pico-second range. The NDK DuCULoN is outrageously good (100-200fS?) but is too expensive ($1,500) for my project.

So, is there anything "in between" -- closer to $50 -- that will provide high femto-second audio jitter performance (500-700fS)? Am especially interested in audio range phase noise spec (10Hz - 10kHz), see below,

...................10Hz...........10kHz

Crystek..........-97dBc..........-161dBc
NDK..............-116dBc..........-175dBc

Brand "X"........-105dBc..........-168dBc <== my ideal $50 value proposition 🙂

Thanks

PULSAR CLOCK is available now.

Pulsar Clock & Power

My system: NAS-> beaglebone black (Botic Linux driver) -> BBB-DSD Interface Adapter Module -> special AKX-S03 Digital Isolator & Re-clocker - Synchronous Master Clock with PULSAR CLOCK-> Northstar DAC

ACKO https://sites.google.com/site/ackodac/

A clock signal from PULSAR CLOCK will be transmitted to beaglebone black and Northstar DAC.

Thanks, Cyrillu. I checked your website, but there are no specifications given. Could you include a phase-noise plot? Also, your clock is $400, which is significantly more than I want to spend.
