2) Ideal sine wave generated by ROM data
Digital signals generated by AKD43XX are used. PORT3 (ADC/ROM) is used to interface with AK43XX.
Master clock is sent from AKD4363 to AKD43XX and LRCK, BICK, SDTI are supplied from AKD43XX to
AKD4363. In case of using external clock through a BNC connector (J4), select “BNC” on JP14 (CLK) and
short JP15 (XTE).

3) DIR(CS8414)
PORT4 (TORX174) is used for the evaluation using such as test disk. The DIR generates MCKI, BICK,
LRCK, SDTI from the received data through optical connector. In this case, the EXT bit of AK4363 should be
“1” (External clock mode). Select “RCA” or “OPT” on JP16 (RCA/OPT) in case of using RCA connector (J3)
or optical connector (PORT4: TORX174).
