1. Evaluation Board Manual Operation sequence
1) Set up the power supply lines. [VA] (red) = 2.7 5.5V or +15V [VD] (orange) = 2.7 5.5V [VCC] (red) = 3.3V [AGND] (black) = 0V [DGND] (black) = 0V
: for VA of AK5381 (typ. 5.0V) : for VD of AK5381, 74HC14 (typ. 5.0V) : for AK4114 : for analog ground : for logic ground
Each supply line should be distributed from the power supply unit. 2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.) 3) Power on. The AK5381 and AK4114 should be reset once bringing SW2 = “L” upon power-up.
Evaluation mode
(1) Slave Mode (1-1) A/D evaluation using DIT function of AK4114 PORT2 (DIT) is used. DIT generates audio bi-phase signal from received data and which is output through optical connector (TOTX141). It is possible to connect AKM’s D/A converter evaluation boar……
