DESIGN HIGHLIGHTS
3.1
DIGITAL ISOLATION
The IRIS 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
FEMTO CRYSTAL OSCILLATOR
The IRIS is equipped with dual FEMTO Clocks operating at audio frequencies 45.1584Mhz,
49.152Mhz. The dual FEMTO Clocks are powered by the o-core transformer, multi-stages
linear regulators. The clean linear power supply ensure superior stability and linearity of the
FEMTO Clocks output frequency.
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 FEMTO CLOCK, located right in the DDC.
