​PLL with Skyworks Si5381​ – High-performance phase-locked loop chip.

​External 10MHz Master Clock Input​ – BNC connector with auto-switching capability.

​SFP Optical Isolation​ – Built-in fiber optic isolation switch system for network signal purification and noise reduction.

​Native USB 2.0 Output​ – Direct output from CPU without signal conversion, minimizing loss and interference.

​Multi-Channel Independent Power Supply​ – EMI filtering + high-speed rectification and filtering for clean power delivery.

High-Resolution Audio Support​ – DSD 512 (Native DSD) and PCM.

Sepcifications

1. Raspberry Pi CM4-Based Architecture​

RPI Pro utilizes the Raspberry Pi Compute Module 4 (CM4), delivering native USB output without PCIe conversion, reducing signal loss and interference. Compatible with popular systems like Volumio, Ropieee, Moode, and PiCorePlayer. Pre-installed with Ropieee for easy setup—stream directly from your phone to your DAC with superior quality compared to Bluetooth.

​2. High-Precision Clock System​

  • Equipped with an ultra-low phase-noise SC-cut OCXO (-100dBc/1Hz typ.) as the master clock reference.
  • Skyworks Si5381 PLL generates synchronized clock signals for the CM4, network controller, and USB interface.
  • Features a 10MHz external clock input (BNC) for advanced reference clock integration, with automatic switching.

​3. Native USB Output with Isolation​

USB 2.0 port is directly driven by the CM4 CPU, bypassing conversion chips. Enhanced with a high-speed isolation IC (3165) and dedicated power supply for studio-grade audio transmission. Ensures stable playback of high-resolution PCM and DSD files, delivering uncompromising fidelity.

​4. High-Performance Network Control​

Dual RJ45 and SFP ports enable fiber-optic network isolation, significantly reducing electrical noise and improving signal integrity.

​5. Precision DC Power Supply​

  • 30VA toroidal transformer with EMI filtering.
  • High-speed rectification and multi-stage filtering with premium electrolytic capacitors.
  • Three independent DC-DC power circuits optimized for high-speed digital performance and microvolt-level low noise.
