(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
digital-amplifier, which equips DIR input. Nothing should be connected to PORT1 (DSP). The DIF1 of SW1
(MODE) should be set to “H”.
JP5
MCLK
(2-2) Master clock is fed externally.
PORT1 (DSP) is used. MCLK is provided to the AK5381 through PORT1. JP5 (MCLK) should be open. The
DIF1 of SW1 (MODE) should be set to “H”.
