Each supply line should distributed from power supply unit. evaluation mode, jumper pins switches. (See followings.) Power AK5381 AK4114 should reset once bringing upon power-up.
Evaluation mode
Slave Mode (1-1) evaluation using function AK4114 PORT2 (DIT) used. generates audio bi-phase signal from received data which output through optical connector (TOTX141). possible connect AKM's converter evaluation boards digital-amplifier, which equips input. Nothing should connected PORT1 (DSP).
MCLK
(1-2) interface signals including master clock externally. PORT1 (DSP) used. interface signals (MCLK, SCLK, LRCK) provided AK5381 through PORT1. (MCLK) should open. DIF1 (MODE) should "H".
