SC-Pure is a top-level audiophile clock made from the best selected SC-CUT crystals. To achieve the highest possible low phase noise performance, an advanced oscillator architecture has been developed. The sound quality can be significantly enhanced by replacing existing clocks with SC-Pure in DACs, DDCs, or network streamers.
- True SC-CUT crystal.
- A specially designed pure sine topology has been introduced to convert the ultra-high-purity sine signal into a square wave directly from the SC-CUT crystal resonator, bypassing any active components. As a result, the best possible low-phase noise performance can be achieved.
- Extremely low close-in phase noise and phase noise floor make SC-Pure capable of challenging any high-end clocks in the world.
- Femtosecond RMS phase jitter.
- In standard compact size DIP14 package with 3.3V power supply voltage and LVCMOS output. Plug and play. Easy to install for all applications.
- Featuring an OE standby function to eliminate interference from unselected frequencies, the SC-CUT crystal can still operate in low-power mode without disrupting the break-in process.
- Operating the standard 83ºC OCXO crystal at room temperature, the frequency will be approximately 20ppm lower than the rated frequency, which is the natural characteristic of the SC-CUT crystals.
- Dual shield cans are located on both the top and bottom sides of the PCB for the best possible EMI noise suppression.
- A 3.3V ultra-capacitor or a LiFePO4 battery power supply can be used directly to optimize the performance. Also has a LED power indicator.
- One-year limited warranty and lifetime service.
Note: Please be very careful about the orientation when you install the SC-Pure clocks. Reversed orientation can damage the SC-Pure and can not be covered by the warranty.

I think the SC-Pure #80A 45.1584 clock is amazing. Immediately the instrument definition and placement in the stereo field improved as soundstage grew even bigger. I have since ordered the 49Mhz clock.
I bought both 22MHz and 24MHz SC Pure XOs for the reclocker board on my RTZ DAC as an upgrade to the Crystek XOs. I was a little sceptical of exactly how much of an improvement they could make, but was very surprised. I started listening after only 8 hours continuous run in, but they had already made a marked improvement that was very obvious. Much more separation between instruments and greater grip, even with complex material. Timbre and decay were markedly improved. Very happy I did!
I used AF200 DDC for SC-Pure clock drop-in to get the low-phase noise digital clocking
Waiting for fully burning in and testing in different systems and compare with other clocks
Make sure where pin 1 is located and assemble. Additional shielding would help (picture 4) or some guides here https://youtu.be/gh4oZnVju84
Thank you I Canada for providing fantastic clocks at a truly reasonable price given their outstanding performance. Also thank you for your kind advise, patience and great service. Highly recommended!
The clock is really awesome, thanks.
