Specification

GUSTARD U26 — USB Digital Interface (DDC) • DSD2048 • PCM 1.536 MHz • Full Isolation

Precision digital bridge with OCXO clocking, dual I²S (LVDS) outputs, and full-format hi-res PCM/DSD support.

USB 2.0 (UAC2) PCM up to 32-bit/1.536 MHz DSD Native up to DSD2048 OCXO SC-cut K2 High-Perf. PLL Full Isolation Dual I²S-H (LVDS) Coax / AES / Optical 10 MHz Clock In Toroidal Linear PSU

Overview

The GUSTARD U26 is a reference-grade USB digital interface designed to extract a pristine digital signal from your computer or mobile source and deliver it to DACs via I²S-over-HDMI (LVDS), AES/EBU, Coaxial, and Optical outputs. A deeply customized Gustard × Amanero USB solution with an ARM® Cortex-M7 (i.MX RT1011) controller ensures stable, low-latency data handling of extreme sample rates. The U26 employs Full Isolation Technology to block PC noise, and a precision clock system built around an SC-cut OCXO and K2 PLL for ultra-low phase noise and jitter.

Key Features

Full-format hi-res: PCM up to 32-bit/1.536 MHz; DSD Native up to DSD2048 (≈90.3168 MHz) and DoP up to DSD512.
Full Isolation Technology: High-speed digital isolation on the USB/I²S path to eliminate ground noise and common-mode interference from the host.
OCXO + K2 PLL clocking: SC-cut OCXO master clock with PLL synthesis (98.3040/90.3168 MHz) for sharply defined, ultra-low-jitter edges.
Dual I²S-H outputs (LVDS over HDMI): With adjustable pin assignment for broad DAC compatibility.
Rich digital I/O: I²S (LVDS), AES/EBU (XLR), Coaxial (RCA), Optical (TOSLINK); plus 10 MHz BNC clock input.
Custom drivers & tuning: Amanero 32-bit USB audio driver (ASIO) with adjustable buffer/latency for stability or lowest-latency tuning.
Extremely pure power: Audio-grade toroidal transformer, dual rectifier bridges, discrete regulation + ultra-low-noise LDOs, and 80,000 µF bulk filtering.
Robust chassis: Full aluminum alloy enclosure for EMI shielding and mechanical stability.

Engineered For Precision

Professional USB core
Gustard & Amanero co-developed USB interface with ARM® Cortex-M7 processing for real-time handling of extreme sample rates. Driver-free on macOS/Linux; ASIO on Windows.

Digital signal shaping (CPLD)
Re-clocks and re-shapes isolated I²S to suppress additive jitter introduced by the isolation stage.

Clock I/O & UI
10 MHz BNC clock input (50 Ω, 0~20 dBm). Front-panel controls for sample rate, I²S pinout, screen brightness, and internal (white) / external (blue) clock status.

Power architecture
Independent supplies for USB, digital and clock domains minimize cross-coupling. Discrete regulators and metal-can devices with dedicated heat sinks maintain low noise under high load.

Isolation path
High-speed isolation (≈200 Mbps class) breaks noisy PC ground loops and blocks RF ingress before precision clocking, yielding cleaner, more stable output to your DAC.

Digital Inputs

USB	USB Type-B (female), USB 2.0 High-Speed (UAC2). OS support: macOS 10.6+, Linux (UAC2 kernel), Windows (ASIO driver), Android/iOS via OTG/USB-host.*
