Description
The DEM-DIR9001 is an evaluation board for the low jitter, Digital Audio Interface Receiver DIR9001. It is
operated by either a single +3.3 V power supply, or a +5 V power supply.
The DEM-DIR9001 has both an Optical Toslink input and an Coaxial input for the SPDIF interface which
can achieve standard digital audio interface format IEC60958, AES/EBU, and JEIAT CPR-1205 (former
EIAJ CP-1201, 340).
The DEM-DIR9001 recovers standard system clock and PCM audio interface clock from incoming biphase
signals such as SPDIF, IEC60958, and AES/EBU. These signals are provided to the audio DAC/DSP,
buffer output, and direct output.
