[AKD4648-C]
(3-2-4) All interface signals are fed externally
PORT3 (DSP) is used. Nothing should be connected to PORT1 (DIR) and PORT2 (DIT).
BICK, LRCK, and SDTI are supplied from PORT3.
The jumper pins should be set as follows.
JP14
4115_MCKI
JP15
DIR_MCLK
JP16
BICK
JP17
LRCK
JP19
DIR_SEL
JP21
SDTI
JP20
JP2
SDTO_IN
Slave Master
DIR ADC
RIN3 VCOC
(4) PLL Master Mode
(4-1) Evaluation of A/D using DIT of AK4115
PORT2 (DIT) and PORT3 (DSP) are used. Nothing should be connected to PORT1(DIR).
The system clock (PLL reference clock) should be connected to MCLK of PORT3.
In case of supplying MCKO to DSP, the JP14 (4115_MCKI)’s lower side should be connected to MCLK of DSP.
X’tal oscillator should be removed from X1.
In Master Mode, BICK and LRCK of AK4648 should be input to AK4115. Please refer to Table2 on page 11.
The jumper pins should be set as follows.
JP14
4115_MCKI
JP15
DIR_MCLK
JP16
BICK
