AK5357 Evaluation Board Rev.2
GENERAL DESCRIPTION
AKD5357-B is an evaluation board for the digital audio 24bit 96kHz A/D converter, AK5357. AKD5357-B
has analog input circuits and a digital interface transmitter,and can achieve the interface with digital audio
systems via opt-connector.

Operation sequence
1) Set up the power supply lines.
[VA]
(red)
= 2.7 ∼ 5.5V or +15V
[VD]
(orange) = 2.7 ∼ 5.5V
[VCC]
(red)
= 3.3V
[AGND] (black)
= 0V
[DGND] (black)
= 0V
: for VA of AK5357 (typ. 5.0V)
: for VD of AK5357, 74HC14 (typ. 5.0V)
: for AK4114
: for analog ground
: 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 AK5357 and AK4114 should be reset once bringing SW2 = “L” upon power-up.
Evaluation mode
(1) Slave Mode
(1-1) A/D evaluation using DIT function of AK4114
PORT2 (DIT) is used. DIT generates audio bi-phase signal from received data and which is output through
optical connector (TOTX141). It is possible to connect AKM’s D/A converter evaluation boards on the
digital-amplifier, which equips DIR input. Nothing should be connected to PORT1 (DSP).
JP5
MCLK
(1-2) All interface signals including master clock are fed externally.
PORT1 (DSP) is used. All interface signals (MCLK, SCLK, LRCK) are provided to the AK5357 through
PORT1. JP5 (MCLK) should be open. The DIF1 of SW1 (MODE) should be set to “H”.

(2) Master Mode
(2-1) A/D evaluation using DIT function of AK4114
PORT2 (DIT) is used. DIT generates audio bi-phase signal from received data and which is output through
optical connector (TOTX141). It is possible to connect AKM’s D/A converter evaluation boards on the

MCLK
(2-2) Master clock is fed externally.
PORT1 (DSP) is used. MCLK is provided to the AK5357 through PORT1. JP5 (MCLK) should be open. The
DIF1 of SW1 (MODE) should be set to “H”.

OPEN : Separated.
SHORT : Common. (The connector “DGND” can be open.) <Default>
2. JP2 (CKS1) : Setting of CKS1 pin for AK5357
H : Master mode
L : Slave mode <Default>
3. JP3 (VA) : Select VA for AK5357
VA : Supply from VA connector <Default>
REG : Supply from regulator. VA connector should be supplied +15V.
4. JP4 (VD) : Select VD for AK5357
VA : Supply from VA connector
VD : Supply from VD connector <Default>

Note: AK4114 does not support MCLK=384fs/512fs/768fs.
PORT1 (DSP) should be used when MCLK=384fs/512fs/768fs.
The function of the toggle SW
Upper-side is “H” and lower-side is “L”.
[SW2] (PDN): Resets the AK5357 and AK4114. Keep “H” during normal operation.
