DESIGN HIGHLIGHTS
3.1
DIGITAL ISOLATION
The GAIA Digital Signals are completely isolated by the 50-Mbps high speed photocouplers.
The optical isolation yields even lowered noise-floor and achieved high signal to noise ratio.
3.2
OVEN-CONTROLLED CRYSTAL OSCILLATOR – OCXO
The GAIA is equipped with dual OCXO operating at audio frequencies 45.1584Mhz,
49.152Mhz. Encapsulated in a metal casing, located at the centre of the DDC, these OCXO
are specially designed for high-end audio applications with ultra-low phase-noise and ultra-
accuracy. The dual OCXO are powered by the o-core transformer, supplying constant
current to the OCXO. The adequate power reserves ensure the superior linearity and
stability of the OCXO.
3.3
ADAPTIVE FIFO BUFFER RECLOCKING
The DENAFRIPS approach to address the jitters issue by FIFO BUFFER RECLOCKING. The
adaptive FIFO buffer store the source digital audio data in the memory. These data are read
from the memory using the ultra-low phase noise, ultra-accuracy OCXO, located right in the
DDC.
This technology is close to the perfection, especially so with the local OCXO. The jitter is so
small that it can be neglected.
