(1) Evaluation of A/D using DIT (Optical Link) <Default Setting)
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 PORT3. When using an external
clock through a BNC connector, select “EXT” on JP11 (CLK) and short JP14 (XTE).

All interface signals are provided to the AK5356 through PORT3. AKM’s D/A converter evaluation boards can
be also connected to PORT3.
