[AKD4104-A]
„ Operation sequence
1) Set up the power supply lines.
[VDD] (Red) = 2.7 ∼ 3.6V (typ. 3.3V, for AK4104)
[VCC] (Red) = 2.7 ∼ 3.6V (typ. 3.3V, for 74LVC541 and for logic)
[AGND] (Black) = 0V
[DGND] (Black) = 0V
Each supply line should be distributed from the power supply unit.
2) Set-up the evaluation modes, jumper pins (See the followings.)
3) Power on.
AK4104 should be reset once by bringing SW1 “L” upon power-down.
AK4104 can power-up when bringing SW1 “H”.
„ Evaluation mode
D/D part evaluation using PORT3 (DSP), and supplying all interface signals from external equipments
In case of using PORT3 (DSP), and supplying signals (MCLK, BICK, LRCK, SDTI) that is needed for the
AK4104 from external equipments, set up jumper pins as following.
① JP2 (CDTO / SDTI2) : CDTO / SDTI2 pins
CDTO: CDTO be selected 。<Default>
SDTI2: SDTI2 be selected。
③ JP3 (SDTI2) : TEST1 pin
VDD: shorted with GND。<Default>
GND: shorted with GND。
③ JP15 (VDD) : VDD and VCC can be shorted
OPEN: Separate VDD and VCC。
SHORT: Short VDD and VCC。<Default>
④ JP16 (GND) : AGND and DGND can be shorted
OPEN: Separate AGND and DGND。
SHORT: Short AGND and DGND。<Default>
