Our regular DigiOne has no equal.
In our quest for digital perfection, we asked how we can improve the design and give you the ultimate DigiOne.
First, we decided to use more board space (we are using 2 boards), the PCB area increased 220%. First board is the “dirty side” and top board has the “clean side”. With the extra space, we used the best decoupling capacitors (film) on everything that’s important (clocks, buffers, flip flops). Also, with this extra space we added a supercap on the “clean side” so most of the electrons come from this onboard “buffer” (there is so much power onboard that DigiOne Sig can run a few seconds without any power attached to the clean side).
We also decided to use 2 power supplies. The “dirty power” needs 5V /2-3A (RPI power). The “clean side” needs about 100mA and accepts from 5V to 6V. You can use anything on it, linear power supply or pure batteries power.
Thirdly, we changed the clocks to the latest from NDK (ultralow jitter SDA) that have lower phase noise than the previous generation.
The Digione Signature needs 2 PSU's to run.
We strongly recommend you purchase the battery pack or use a very good power supply for the clean side. You can use an additional 5V 3A PSU to feed the clean side, although a battery pack is the recommended set up.
The Digione has a galvanic isolator for both power and signals. You do not need an extra isolator. Additionally, DigiOne has a double relocking of the S/PDIF stream (one of them taking care of metastability and the second one taking care of realigning the data). You do not need another reclocker (like Kali).
- It’s a "re-clocker". The unit has its own clocks so it does not rely on the jittery RPI clocks
- It's galvanically isolated. The clean board is isolated (ground and signals) from the dirty side
- It needs 2 PSUs, one for 5V/2A-3A (RPI) and a second power 5V to 6V 100mA. We do recommend the cleanest power supply possible (batteries, linear but even a good SMPS will work)
- Old driver is compatible for both units (chose DigiOne on your favorite player)
- Measured jitter has decreased further, less than 400fs (tested at buffer)
- Output is coaxial/BNC and rise/fall time is 1ns and voltage level is exactly as per guidelines (550mV on coaxial) measured at end of transmitting cables
- Includes 2 x DC to USB-C Adapter Cables
