(1) Evaluation of A/D using DIT (Optical Link)

PORT2 (DIT) and X2 (X’tal) 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 PORT1 (DIR), PORT3
(ROM). In case of using external clock through a BNC connector (J5), select EXT on JP11 (CLK) and short JP8
(XTE) and open JP13 (EXT). AK4112B should be powered down.
