LAIV Audio Harmony µDDC

With the Harmony µDDC, Laiv Audio presents a digital interface and reclocker that considerably reduces phase noise and jitter for a more natural sound rendering in an open stage. The latter is based on a Femto clock to ensure the most stable clock signal possible. Connections include USB-B, AES, I2S and coaxial, plus a galvanically isolated I2S output. Thanks to its FPGA-based signal processing, the Harmony µDDC can handle signals up to PCM 768kHz and DSD512. A 10MHz clock input is also available if you wish for an external clock to reclock your signal.

The Harmony µDDC uses an FPGA to manage the routing and processing of complex digital signals with extremely low latency, guaranteeing bit-perfect data processing for high-resolution formats. A CPLD manages the synchronization of critical signals, minimizing phase noise and jitter. The femto clock reduces jitter to an infinitesimal level. A robust FIFO buffer system synchronizes incoming and outgoing signals, eliminating timing irregularities caused by the source. The I²S output is galvanically isolated, preventing electrical interference and noise propagation from the source to downstream components.
