: typ. 3.0V, VA pin
: typ. 3.0V, VD pin
: for digital logic except the AK5355
: for analog ground (including VSS of AK5355)
: for logic ground
Each supply line should be distributed from the power supply unit.
VD and VA must be the same voltage level.
2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.)
3) Power on.
The AK5355 and AK4103 should be reset once bringing SW1 = SW3 = “L” upon power-up.
„ Evaluation mode
Applicable Evaluation Mode
(1) Evaluation of A/D using DIT (Optical Link) <Default Setting>
(2) All interface signals including master clock are fed externally.
(3) Evaluation of A/D using DIT at MCLK = 384fs
(1) Evaluation of A/D using DIT (Optical Link)
PORT1 (DIT) is used. On board DIT (AK4103) converts A/D data to an audio biphase signal, which is output
through optical connector (TOTX176). It is possible to connect AKM’s D/A converter evaluation boards or the
digital-amplifier that equips DIR input etc. Nothing should be connected to PORT2. DIT (AK4103) operates at
SW3=“H”. When using an external clock through a BNC connector (J3), select “EXT” on JP4 (CLK) and short
JP3 (XTE).

(2) All interface signals including master clock are fed externally.
All interface signals are provided to the AK5355 through PORT2. AKM’s D/A converter evaluation boards can
be also connected to PORT2.
