EVALUATION BOARD MANUAL
„ Operation sequence
1) Set up the power supply lines.
[+15V] (Green) = +15V
[-15V] (Blue) = -15V
[5394_VA] (Red) = 4.75~5.25V : VA of AK5394A
[5394_VD] (Orange) = 3.0~5.25V : VD of AK5394A
[4103_VD] (Red) = 4.75~5.25V : VDD of AK4103A
[AGND] (Black) = 0V
: Analog Ground(Include AGND and DGND of AK5394A)
[DGND] (Black) = 0V
: Digital Ground(Logic part)
When “5394_VD” is operated on 3.0~4.75V, JP15(IF/5V) should be connected to “5394_VD”.
Each supply line should be distributed from the power supply unit.
2) Set-up the evaluation modes, jumper pins and DIP switches. (See the followings.)
3) Power on.
The AK5394A and AK4103A should be reset once by bringing SW1 (PDN) to “L” after power-on.
After that, release the reset by bringing SW1 (PDN) to “H”.
Keep SW1(PDN) “H” during normal operation.
