„ Operation sequence
1) Set up the power supply lines.
1-1) When AVDD, DVDD, SVDD, and VCC are supplied from the regulator. (AVDD, DVDD, SVDD, and
VCC jack should be open.). See “Other jumper pins set up (page 10)”. <default>

Each supply line should be distributed from the power supply unit.
AVDD and DVDD must be same voltage level.
2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.)
3) Power on.
The AK4631VN and AK4114 should be reset once bringing SW1, 2 “L” upon power-up.
„ Evaluation mode
In case of AK4631VN evaluation using AK4114, it is necessary to correspond to audio interface format for
AK4631VN and AK4114. About AK4631VN’s audio interface format, refer to datasheet of AK4631VN.
About AK4114’s audio interface format, refer to Table 2 in this manual.
Applicable Evaluation Mode
(1) Evaluation of loop-back mode (A/D → D/A) : PLL, Master Mode (Default)
(2) Evaluation of loop-back mode (A/D → D/A) : PLL, Slave Mode (PLL Reference CLOCK: MCKI
pin)
(3) Evaluation of loop-back mode (A/D → D/A) : PLL, Slave Mode (PLL Reference CLOCK: BICK or
FCK pin)
(4) Evaluation of using DIR of AK4114 (opt-connector) : EXT, Slave Mode
(5) Evaluation of using DIT of AK4114 (opt-connector) : EXT, Slave Mode
