Laiv Harmony µDDC - Compact Digital Audio Bridge with Ultra-Precision Clocking and Signal Purification
Unlock Unparalleled Digital Audio Purity
Designed for discerning audiophiles, the Laiv Harmony µDDC is a high-performance digital audio bridge that blends cutting-edge technology with elegant industrial design. With proprietary buffering and reclocking, galvanic isolation, and femto-level clocking precision, the µDDC ensures exceptional timing accuracy and sonic integrity—making it the ultimate addition to high-resolution audio systems.
Sleek & Compact Form Factor
Despite its modest footprint, the Harmony µDDC is built for serious performance. Its minimalist chassis fits easily into any desktop or rack-mounted setup, ideal for modern high-end systems where space efficiency and aesthetic harmony matter.
- Perfect for Desktop Integration: Maintains a tidy workspace without sacrificing high-end features.
- Premium Build Quality: Milled from a solid block of aerospace-grade aluminum using precision CNC techniques, ensuring excellent rigidity, effective passive heat dissipation, and a luxurious tactile finish.
Clocking Precision Beyond Compare
At the heart of the Harmony µDDC lies a high-stability ultra-low phase noise femto clock sourced from an industry-leading timing solutions provider. This ensures digital signal timing is exceptionally stable, dramatically reducing jitter and improving audio clarity.
- Ultra-Low Jitter Femto Clock: Enables a clean, time-aligned digital output for refined sonic transparency.
- Support for External 10MHz Master Clock: Audiophiles with advanced setups can unlock even greater timing precision and system-wide synchronization by connecting external master clocks.
Proprietary FIFO Buffering & Reclocking Engine
The Harmony µDDC leverages Laiv’s proprietary FIFO buffer architecture, meticulously designed to re-time digital signals before transmission. This buffer mechanism works in tandem with the femto clock to eliminate timing anomalies introduced by upstream components such as computers, streamers, or USB interfaces.
- Jitter Elimination at Source: Reclocking minimizes upstream timing errors, stabilizing the signal and delivering superior dynamics and soundstage definition.
- Enhanced Resolution: Experience more nuanced transients, ambient detail, and microdynamics—hallmarks of truly high-end digital audio playback.
Advanced Digital Signal Processing Architecture
Laiv employs a powerful dual-processor design within the µDDC, combining an FPGA and CPLD for optimal signal control:
- Field-Programmable Gate Array (FPGA): Manages all digital routing with extreme accuracy, supporting sample rates up to PCM 768kHz and DSD512, ensuring bit-perfect transmission.
- Complex Programmable Logic Device (CPLD): Handles high-speed timing operations, reducing phase noise and ensuring precision reclocking at every stage of the signal path.
Galvanically Isolated I2S Output
The µDDC offers galvanically isolated I2S outputs, protecting downstream DACs from ground loop noise and interference while preserving signal purity.
- Noise-Free Performance: Electrical isolation ensures zero interference across digital domains, maximizing signal-to-noise ratio and eliminating subtle but audible distortion.
- Multiple I2S Configurations Supported: Seamless compatibility with a wide range of DACs via configurable pin mappings and output protocols.
Effortless User Interface
Designed with simplicity in mind, the Harmony µDDC features an intuitive interface with tactile buttons for straightforward input selection and operation. No software installation is required—just plug, play, and enjoy.
- Input Selection at Your Fingertips: Instantly switch between connected digital sources via physical buttons.
- Status Indicators: Discreet LEDs provide immediate visual feedback on operational status and input selection.
