■ Digital Audio Interface
The NJU26040-09B audio interface provides industry standard serial data formats of I2S, MSB-first
left-justified or MSB-first right-justified. The NJU26040-09B audio interface provides three data input, SDI0,
SDI1, SDI2 and three data outputs, SDO0, SDO1 as shown in table 2, table 3 and Fig.1. An audio interface
input and output data format become the same data format.

■ Host Interface
The NJU26040-09B can be controlled via Serial Host Interface (SHI) using either of two serial bus
formats: I2C bus or 4-Wire serial bus.(Table 4) Data transfers are in 8 bit packets (1 byte) when using either
format.

Note : SDA /SDOUT pin is a bi-directional open drain.
This pin requires a pull-up resistance in both I2C bus and 4-Wire serial mode.
* When the power supply (VDD= +3.3V) is supplied to NJU26040, these pins become
+5.0V Input tolerant.
