Let's Shape the Douk Audio U7 DDC reclocker!

[Douk Audio]

Hello all ASR members,

We are really happy and grateful that the U2PRO DDC, released last year, was well received by many users.

At the same time, inspired and helped by Douk Audio's super good friend, we started a new DDC project at the end of 2025, designed specifically for streamers and DACs that lack USB input.

The project now has an initial prototype. Below are the product specs and design drawings:

Input: Optical + Coaxial
Output: Optical + Coaxial + BNC
Input sample rate will be upsampled to: 96kHz or 192kHz
Two adjustable sample rate settings
Clock: High-precision, low-temperature-drift clock
Chassis: Full aluminum alloy
RCA jacks: Solid copper
Dimensions: 70 × 95 × 30 mm

Our product team would also like to gather more suggestions for finalizing the version.
Whether it's about functionality, appearance, components, or specifications, we encourage everyone to share your opinions freely so we can hear more of your voices and needs.

Thank you all again!

How do you source a reference clock? Without RJ45 how do you use IEEE 1588?
