[AKD4344-A]
Other Jumper pins set up
(1) JP15 (VDD): VDD and VCC
OPEN: Separated
SHORT: Common. (The connector “VCC” can be open.) <Default>
By opening the connector “VCC”, shorting JP15 (VDD) and supplying 3.3V to the connector “VDD”, the
connector “VDD” can supply 3.3V to all circuits
(2) JP16 (GND): Analog ground and Digital ground
OPEN: Separated
SHORT: Common. (The connector “DGND” can be open.) <Default>
(3) JP10 (BCFS): Select the BICK of the AK4344
x1: BICK=128fs in case of MCLK=256fs/384fs/512fs/768fs.
BICK=64fs in case of MCLK=192fs.
x2: BICK=64fs in case of MCLK=128fs/256fs/384fs/512fs/768fs. <Default>
BICK=32fs in case of MCLK=192fs.
BICK=128fs in case of MCLK=1024fs/1536fs.
x4: BICK=32fs in case of MCLK=128fs/256fs/384fs/512fs/768fs.
BICK=64fs in case of MCLK=1024fs/1536fs.
x8: BICK=32fs in case of MCLK=1024fs/1536fs.
(4) JP11 (DIV), [JP9] (CLK), [JP13] (LRFS)
When using J1 (EXT), these jumper pins should be set according to Table 1.
(5) JP2 (CDTO / SDTI2): Select the signal of CDTO / SDTI2 pin
CDTO: Select the CDTO<Default>
SDTI2: Select the SDTI2
(6) JP8 (SDTI2): Select the input of SDTI2 pin
PORT3: Input the signal from PORT3
GND: Input the “0” Data <Default>
(When JP2 (CDTO / SDTI2): setting is CDTO, Set to GND)
