Basic Connection and Operation
•
Install REGTEST_I2C and other programs attached to the EVM into the appropriate folder of the PC
that is used to control this EVM.
•
Confirm EVM settings. SW053 must be all OFF (High). JP051 SCL, SDA, MDO, and DOUTS must be
OFF, OFF, OFF, and ON, respectively.
•
Connect the 5-V and
±
15-V power supplies to V
CC
,
±
AV
CC
, and GND on CN051–CN055. If external
3.3 V is used on CN056, jumper CN057 must be removed. The
±
15-V power supplies are required for
2-Vrms input and 2-Vrms output.
•
Connect the SPDIF input to CN059 (coaxial) or U053 (optical) and output to CN058 (coaxial) or U052
(optical), and select coaxial or optical for SPDIF input and output using SW001 and SW051. Also,
select the SPDIF output source from the analog-to-digital converter (ADC) output or the
digital-to-analog converter (DAC) input using SW052.
•
Select the system clock source from x’tal or SPDIF input recover clock using SW004, select the
system clock using SW003 SCF1/0 for DIR1703 and using SW005 CLK1/0 for DIT4096, and select the
system clock frequency for x’tal mode using JP001 setting.
•
Set the interface format (24-bit I
2
S) using SW003 FMT1/0 for DIR1703 and using SW005 FMT1/0 for
DIT4096.
•
Set the channel status for DIT4096 using SW006 if required. (It is not required for PCM3052A
evaluation.)
•
Select the analog input/output configuration according to application interface, specifically, select the
DUT PCM3052A V
CC
from 5 V or 4.5 V using JP109, the Mic input configuration of single ended or
differential using JP110, the ADC input full scale from 2 Vrms or 1 Vrms using JP105/6, and the DAC
output LPF band width from 20 kHz or 40 kHz using JP101-104.
