Deep Dive: Technical Innovations of LAiV Harmony uDDC

The Laiv Harmony uDDC combines cutting-edge engineering and precision signal processing to deliver uncompromised digital audio quality. Here’s a closer look at the advanced technologies driving this high-performance device:

FPGA & CPLD Signal Processing

High-Precision FPGA Core

The Harmony uDDC employs a Field-Programmable Gate Array (FPGA) to manage complex digital signal routing and processing with ultra-low latency. This ensures bit-perfect data handling for high-resolution formats like PCM768 and DSD512.

CPLD for Signal Optimization

Complementing the FPGA, a Complex Programmable Logic Device (CPLD) handles critical signal timing, minimizing phase noise and jitter. This division of processing tasks ensures high efficiency and precision in every operation.

Femto Clock FIFO Buffer System

Femto-Second Precision

The integrated femto clock reduces jitter to negligible levels, ensuring the timing integrity of the digital audio signal. This is particularly critical for maintaining the transparency of high-resolution formats.

FIFO Buffer Implementation

A robust First-In-First-Out (FIFO) buffer system synchronizes incoming and outgoing signals, eliminating timing irregularities caused by source devices. The result is a smooth, clocked output that retains the original sonic characteristics.

Reclocking Technology

Reclocking with Femto Precision

The Harmony uDDC's reclocking mechanism re-aligns the signal timing using the femto clock, effectively "cleansing" the digital signal of jitter introduced by upstream devices. This improves signal integrity and enhances soundstage clarity, dynamics, and resolution.

Galvanically Isolated Output

To maintain signal purity, the I²S output is galvanically isolated, preventing electrical interference and noise propagation from the source to downstream components.

Designed for High-End Integration

Ultra-Wide Format Support

Native PCM up to 768kHz and DSD up to DSD512 compatibility ensures seamless playback of even the most demanding audio formats.

External 10MHz Master Clock Input

For audiophiles using an external reference clock, the Harmony uDDC provides a dedicated 10MHz clock input, enabling even greater precision and synchronisation.
