DIR9001 Evaluation Board

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.
