(2) Master Mode
(2-1) A/D evaluation using DIT function of AK4101
PORT1 (DIT1) and PORT2 (DIT2) are 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 PORT3 (DSP). In case
of using external clock through a BNC connector (J5), select EXT on JP8 (CLK) and short JP5 (XTE) and open
JP10 (EXT).
