Function
I Power Down & Reset Pin
(Pull-up Pin)
When “L”, the AK4101A is powered-down, TXP/N pins are “L” and the
control registers are reset to default values.
I Master Clock Input Pin
I Audio Serial Data Input 1 Pin
I Audio Serial Data Input 2 Pin
(Pull-down Pin)
I Audio Serial Data Input 3 Pin
(Pull-down Pin)
I Audio Serial Data Input 4 Pin
(Pull-down Pin)
-
Power Supply Pin, 4.75V∼5.25V
- Ground Pin, 0V
I/O Audio Serial Data Clock Input/Output Pin
Serial Clock for SDTI pins which can be configured as an output based on
the DIF2-0 inputs.
I/O Input/Output Channel Clock Pin
Indicates left or right channel, and can be configured as an output based on
the DIF2-0 inputs.
I Sampling Frequency Select 0 Pin at Synchronous mode (Pull-down Pin)
I Host Interface Chip Select Pin at Asynchronous mode (Pull-down Pin)
I AK4112B Mode Pin at Audio routing mode
(Pull-down Pin)
0: Non-AKM receivers mode, 1: AK4112B mode
I Sampling Frequency Select 1 Pin at Synchronous mode (Pull-down Pin)
I Host Interface Data Input Pin at Asynchronous mode (Pull-down Pin)
I Sampling Frequency Select 2 Pin at Synchronous mode (Pull-down Pin)
I Host Interface Bit Clock Input Pin at Asynchronous mode (Pull-down Pin)
I Sampling Frequency Select 3 Pin at Synchronous mode (Pull-down Pin)
O Host Interface Data Output Pin at Asynchronous mode (Pull-down Pin)
I Channel Status Bit Input Pin for Channel 1
I Channel Status Bit Input Pin for Channel 2
(Pull-down Pin)
I Channel Status Bit Input Pin for Channel 3
(Pull-down Pin)
I Channel Status Bit Input Pin for Channel 4
(Pull-down Pin)
I Asynchronous/Synchronous Mode Select Pin
(Pull-up Pin)
0: Asynchronous mode, 1: Synchronous mode
I/O Block Start Input/Output Pin
(Pull-down Pin)
In normal mode, the channel status block output is “H” for the first four
bytes. In audio routing mode, the pin is configured as an input. When PDN
pin = “L”, BLS pin goes “H” at Normal mode.
I Clock Mode Select 0 Pin
(Pull-up Pin)
- Ground Pin, 0V
