„ Operation sequence
1) Set up the power supply lines.
1-1) When AVDD, DVDD and VD are supplied from the regulator.
[REG] (Red)
[AVDD] (Orange)
[DVDD] (Orange)
[VD] (Orange)
[AGND] (Black)
[DGND] (Black)
= 5V
= open
= open
= open (for logic)
= 0V
: for analog ground
= 0V
: for logic ground
1-2) When AVDD, DVDD and VD are not supplied from the regulator.
[REG] (Red)
[AVDD] (Orange)
[DVDD] (Orange)
[VD] (Orange)
[AGND] (Black)
[DGND] (Black)
= “REG” jack should be open.
= 2.4 ∼ 3.6V : for AVDD of AK5701 (typ. 3.0V)
= 1.6 ∼ 3.6V : for DVDD of AK5701 (typ. 3.0V)
= 2.7 ∼ 3.6V : for logic (typ. 3.0V)
= 0V
: for analog ground
= 0V
: for logic ground
Each supply line should be distributed from the power supply unit.
2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.)
3) Power on.
The AK5701 and AK4114 should be reset once by bringing SW1, 2 “L” upon power-up.
„ Evaluation mode
In case of AK5701 evaluation using AK4114, same audio interface format should be set for both AK5701 and
AK4114. About AK5701’s audio interface format, refer to datasheet of AK5701. About AK4114’s audio
interface format, refer to Table 2 in this manual.
Applicable Evaluation Mode
(1) Evaluation of PLL, Master Mode (Default)
(2) Evaluation of PLL, Slave Mode (PLL Reference CLOCK: MCKI pin)
(3) Evaluation of PLL, Slave Mode (PLL Reference CLOCK: BCLK or LRCK pin)
(4) Evaluation of using DIT of AK4114 (opt-connector): EXT, Slave Mode
(5) Slave & Bypass Mode
(6) Bypass Mode
