(2) Set up the evaluation mode, jumper pins and connectors according to the follows.
(3) Connect the board to PC with the USB cable packed.
(4) Power On.
(5) Start the control soft and setup the registers.
„ Evaluation Mode
In case of AK7782 evaluation using AK4118A, it is necessary to correspond to audio interface format for
AK7782 and AK4118A. About AK7782’s audio interface format, please refer to datasheet of AK7782. About
AK4118A’s audio interface format, please refer to Table 11 in this manual.
Applicable Evaluation Mode
(1) Evaluation mode of ADC using DIT of AK4118A: CKM Master Mode = 0
(2) Evaluation mode of DSP using DIR/DIT of AK4118A: CKM Slave Mode = 2/4/5
(3) Evaluation mode of SRC using DIR of AK4118A and SMUX port: CKM Master Mode = 0
(4) Evaluation mode of sound (tone) quality using DAC of AK4359
Please refer to the control software manual from page 12 and the datasheet of AK7782 to set up FPGA, AK4118A and
AK7782 from PC.
