AKD4145-A Datasheet, PDF (6/32 Pages) Asahi Kasei Microsystems – Evaluation board Rev.3 for AK4145

[AKD4145-A]
Measurement Mode
The supporting measurement mode is as follows.
1. Evaluation using DIR of AK4114 <Default>
2. Evaluation using ADC of AK5357
3. All interface signals are fed externally
1. Evaluation using DIR of AK4114 <Default>
Measurement path :
Optical connector (PORT1) or BNC (J6) → DIR (AK4114) → AK4145
Please supply biphase signal to Optical connector (PORT1) or BNC connector (J6). DIR generates MCLK, BICK,
LRCK, and SDTI from received data.
(1-1) Set up the jumper pins.
JP6 (RX) should be set according to the RX input. Follow is setting example in Optical connector.

(1-2) Set up the DIP SW (S2).
In case of the AK4145 evaluation using the AK4114, it is necessary to correspond to the audio interface format
for AK4145 (SDTI) and AK4114 (SDTO). About AK4145’s audio interface format, refer to datasheet of
AK4145. About AK4114’s audio interface format, refer to Table. 6 on page 8.
(Note) AK4145’s default setting of Audio interface format is I²S Compatible in parallel mode.
