The DEM-DIR9001 is an evaluation board for the low jitter, Digital Audio Interface Receiver DIR9001. It isoperated 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 whichcan achieve standard digital audio interface format IEC60958, AES/EBU, and JEIAT CPR-1205 (formerEIAJ CP-1201, 340).
The DEM-DIR9001 recovers standard system clock and PCM audio interface clock from incoming biphasesignals such as SPDIF, IEC60958, and AES/EBU. These signals are provided to the audio DAC/DSP,buffer output, and direct output.

+5 V Power supplyConnect the +5 V power supply at CN051 with the 5V jumper connection at the HDR051 connector. For allinternal operations, the +3.3 V power supply is generated by the mounted REG-IC. External +3.3 V is notrequired.
+3.3 V Power supplyConnect +3.3 V power supply at CN052 with 3.3 V jumper connection at the HDR051 connector. All +3.3 Vpower supply is provided from CN052.
SW001 is a reset switch for the DIR9001. External automatic power on the reset circuit is combined.
•Connect the Toslink optical fiber cable connector at U001.•Connect the RCA Coaxial cable connector at CN001.•Optical input or Coaxial input must be selected by SW003 as OPT or COAX.

Description
CN004 and CN005 are PCM audio interface clock outputs (System Clock, LRCK, BCK, and DATA).CN004 is a buffered output with a mounted logic buffer IC. CN005 is a direct output from DIR9001.Caution: Pins on the right side are GND.•SCKO : System Clock (128/256/384/512fs)•BCKO : PCM audio, BCK clock (64fs)•LRCKO : PCM audio, LRCK clock (fs)•DOUT : PCM audio, DATA clock
The external clock can be connected at CN002 (not mounted) by removing the mounted XTAL. This alowsthe user to confirm operation of the DIR9001 by another clock source.

EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the input voltage range of 2.7 V to 3.6 V or 5 V and the output voltage range of 2.7 V to3.6 V.Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there arequestions concerning the input range, please contact a TI field representative prior to connecting the input power.Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to theEVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the loadspecification, please contact a TI field representative.During normal operation, some circuit components may have case temperatures greater than 85 °C. The EVM is designed tooperate properly with certain components above 85 °C as long as the input and output ranges are maintained. These componentsinclude but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types ofdevices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes nearthese devices during operation, please be aware that these devices may be very warm to the touch.
