(3-2-2) Evaluation of D/A using DIR of AK4114
PORT1 (DIR) is used. Nothing should be connected to PORT2 (DIT), PORT3 (DSP) and J11 (EXT).
The jumper pins should be set as the following.
JP14
EXT
JP15
MCLK
JP18
JP21
BICK_SEL LRCK_SEL
JP19
PHASE
JP24
SDTI_SEL
DIR
EXT
DIR 4040 DIR 4040 THR INV DIR ADC
* The AK4114 operates at fs of 32kHz or more. If the fs is slower than 32kHz, this evaluation mode can’t be used.
(3-2-3) Evaluation of Loop-back using AK4114
X1 (X’tal) is used. Nothing should be connected to PORT1 (DIR), PORT2 (DIT), PORT3 (DSP) and J11
(EXT).
The jumper pins should be set as the following.
JP14
EXT
JP15
MCLK
DIR
JP18
JP21
JP22
JP19
BICK_SEL LRCK_SEL 4114_MCKI PHASE
JP24
SDTI_SEL
EXT
DIR 4040 DIR 4040
THR INV DIR ADC
* The AK4114 operates at fs of 32kHz or more. If the fs is slower than 32kHz, this evaluation mode can’t be used.
