terNario FEENG – Flagship Audiovisual Signal Hub

Core Architecture

An acoustics-first six-dimensional digital purification system achieves the perfect balance of electrical isolation and data purity through a four-channel independent network signal architecture. The main controller uses a military-grade Marvell 88e1112 network chipset to build a modular optical network structure. It’s equipped with a patented SFP optical fiber serial communication module, which physically isolates RJ45 ports from three enhanced switching ports, effectively blocking 99.97% of power line-conducted noise.

Space-Time Calibration System (Clock module independent of the switching network architecture)

Setting a new benchmark in acoustic clock engineering, it features a precision timing architecture with an SC-cut VCOCXO (Voltage-Controlled Oven-Controlled Crystal Oscillator). The 25MHz core oscillator maintains a precision of ±0.01ppm within a temperature-controlled chamber. Adopting matured PLL (Phase-Locked Loop) technology from the RF communication field, it forms a two-stage progressive space-time calibration system, achieving a phase noise performance of 1Hz/-98dBc at the reference layer. When cascaded with the 10M reference clock (1Hz/-118dBc) from the terNario LOONG flagship streamer, the entire unit’s phase noise curve stabilizes at 1Hz/-112dBc, maintaining a linear phase response beyond 100Hz—completely avoiding the frequency domain collapse flaws of DDS architectures.

Power Core

The pioneering three-way parallel power system features three Talema transformers and a hybrid linear voltage regulation array to create 48 independent power supply nodes. A three-stage EMI filtering matrix built from WIMA MKP capacitors and Jensen silver oil capacitors, combined with a WE 10A power-line choke coil, reduces motherboard power ripple to 0.5μVrms (typical value)—a critical spec contributing to the analog-like tonality of R2R DACs. A 13,200μF Nichicon ultra-low ESR capacitor array, paired with ON Semiconductor 8A rectifier modules, maintains an ultra-clean 4μV output even under continuous 1.5A load, establishing a “starlight” power supply network for each chip.

Mechanical Sanctuary

Crafted from a 40kg aerospace-grade aluminum billet, the resonance control platform is CNC-milled for 26 hours to form a honeycomb topology cavity. An original ceramic-stainless steel hybrid shock absorption system uses a “sandwich” suspension structure to push the resonance point below 0.8Hz. Along with a semi-floating dynamic top cover design, this reduces internal micro-vibrations by 26dB compared to traditional structures. The 6kg monolithic CNC frame not only supports components but also serves as an acoustic lens for system-wide resonance control.

Exclusive Connection Guide

Isolated Ports: Recommended for upstream devices like routers, acting as the first line of purification in the digital signal chain.
LAN1-3 Audio-Dedicated Channels: Best used for direct connections to streamers, network DACs, and other sensitive equipment.
SFP Optical Link: Ideal for connecting SFP-compatible devices (e.g., NAS), or for extending Wi-Fi coverage.
Cascade Ports: Use with customized SFP modules to build a private optical network matrix.
