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 CLEAN power that can be (5V to 6V) 100mA. We do recommend the cleanest power supply possible (batteries, linear but even a good SMPS will work)
Existing DigiOne 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
Product Description
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 Percent . 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.
