AKD5385B-A
AK5385B Evaluation Board Rev.0
GENERAL DESCRIPTION
AKD5385B-A is an evaluation board for the digital audio 24bit 192kHz A/D converter, AK5385B. The
AKD5385B-A includes the input circuit and also has a digital interface transmitter. Further, the
AKD5385B-A can achieve the interface with digital audio systems via opt-connector.

„ Operation sequence
1) Set up the power supplies lines.
[AVDD] (red)
= 4.75 ∼ 5.25V : for AVDD of AK5385B (typ. 5.0V)
(The default setting of JP2 is “REG”, so AVDD connector should be open.
In this case, the AVDD of AK5385B is supplied from regulator. )
[DVDD] (red)
= 3.0 ∼ 5.25V : for DVDD of AK5385B (typ. 3.3V)
[+15V]
(green)
= +15V
: for Op-amp
[−15V]
(blue)
= −15V
: for Op-amp
[VCC]
(red)
= 5V
: for logic
[AGND] (black)
= 0V
: for analog ground
[DGND] (black)
= 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 AK5385B and AK4103A should be reset once bringing SW1 = “L” upon power-up.
„ Evaluation mode
(1) Slave Mode
(1-1) A/D evaluation using DIT function of AK4103A
PORT1 (DIT) is used. DIT generates audio bi-phase signal from received data and which is output through
optical connector (TOTX176). 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 PORT2 (DSP). In case of using
external clock through a BNC connector (J3), select EXT on JP8 (CLK) and short JP5 (XTE) and open JP10
(EXT).

(1-2) Feeding all clocks from PORT2 (DSP)
Under the following set-up, all external clocks (MCLK, BICK, LRCK) can be fed through PORT2 (DSP). The
A/D converted data is output from SDTO of PORT2 (DSP). Also, the A/D converted data is output through
optical connector (TOTX176).
