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 AK5381 and AK4103 should be reset once bringing SW1 = “L” upon power-up.
Evaluation mode
(1)
Slave Mode
(1-1) A/D evaluation using DIT function of AK4103
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 JP10 (CLK) and short JP7 (XTE) and open JP12 (EXT).
