1. Evaluation Modes

•Applicable Evaluation Mode

(1) DIR(Optical Link)

(2) Ideal sine wave generated by ROM data

(3) Using AD converted data

(4)All interface signals including master clock are fed externally.

(1) DIR(Optical Link) (default)

PORT2 is used for the evaluation using such as CD test disk. The DIR generates MCLK, BICK and LRCK SDATAfrom

the received data through optical connector(PORT2: TORX176).

Fig.3 Jumper set-up (DIR)

(2) Ideal sine wave generated by ROM data

Digital signal generated by AKD43XX are used. PORT1 is used for the interface with AKD43XX. Master clock is sent

from AKD4393 to AKD43XX then LRCK, BICK and SDATA are sent from AKD43XX to AKD4393.
