The PNP Type-X is a high-performance audio device based on the Raspberry Pi 3B, offering independent 5V, 3.3V, and 1.8V power supplies using ultra-low noise LT3045 regulators. Its SoC features an upgraded VCTCXO oscillator with ±0.2ppm stability, ensuring precise timing synchronization. The FifoPi Q7-based I²S FIFO reclocker incorporates low-noise 1-bit reclockers and 44.1/48kHz CCHD-957 oscillators for unmatched signal integrity. It supports Coaxial, BNC, and HDMI (I²S/DSD/DoP) outputs, delivering up to 192kHz S/PDIF and 384kHz HDMI audio output. Powered by a ZA-Rate battery with ultra-low ESR and the PCDC 2024 power circuit, it operates via dual 12V adapters for optimal performance.
