! Audio Interface
The NJU26226 audio interface provides industry serial data formats of I2S, MSB-first Left-justified or MSB-first
Right-justified. The NJU26226 audio interface provides four data inputs, SDI0, SDI1, SDI2 and SDI3, and four
data outputs, SDO0, SDO1, SDO2 and SDO3, as shown in table 2 and 3.

SDO2 L/R, C/Sw, Ls/Rs Lb/Rb, or Mute can be selected (refer to Fig 2.2).
SDO3 L/R, C/Sw, Ls/Rs Lb/Rb, or Mute can be selected (refer to Fig 2.2).
Note: L/R : Front channel
C/Sw : Center channel and Sub woofer
Ls/Rs: Surround channel
Lb/Rb: Surround back channel
! Host Interface
The NJU26226 can be controlled via Serial Host Interface (SHI) using either of two serial bus formats : I2C bus or
4-Wire serial bus. Data transfers are in 8 bits packets (1 byte) when using either format. The SHI operates only in
a SLAVE fashion. A host controller connected to the interface always drives the clock (SCL / SCK) line and
initiates data transfers, regardless of the chosen communication protocol.
The detail I2C bus and 4-Wire Serial bus information are described in the ‘NJU26200 Series Hardware Data
Sheet’.

Note: When 4-Wire Serial bus is selected, The SDA/SDOUT pin is CMOS output. The SDOUT pin does not require a
pull-up resistance.
When I2C Bus is selected, this pin is a bi-directional Open Drain output. This pin, which is assigned for I2C Bus,
requires a pull-up resistance.
The SDA/SDOUT pin isn’t 5.0V Input tolerant. Please note the voltage level (Max voltage is VDDIO).
