I/O
– Digital Ground. Digital ground is 0 V.
– Digital Supply. 3.3 V or 5.0 V nominal.
I Master Clock Input.
Power-down and Reset. When low the AK4393 is in Power-down Mode and held in reset. The
I
AK4393 should always be reset after power-up.
I Audio Serial Data Clock Input. A clock input of 64fs or more is recommended.
I Serial Data Input.
I Left/Right Clock Input. Defines the sampling rate, F s .
Soft Mute Input or Chip Select Input. If the P/S pin (pin 25) is high, SMUTE controls the soft
mute function as follows:
• When SMUTE goes high, the soft mute cycle is initiated.
I
• When SMUTE goes low, the output mute is slowly released.
If the P/S pin is low, SMUTE is the Chip Select Input for the Serial Control Mode. Chipselect is
active when SMUTE is low.
Double Sampling Speed Input. When low, this pin defines the Normal Speed Mode, and
I 128 x F s oversampling is implemented. When high, the DFS pin defines the Double Speed
Mode, implemented with 64 x F s oversampling. This pin features an internal pull-down.
De-emphasis Enable #0 or Control Data Clock Input. If the P/S pin (pin 25) is high, DEM0 is
I used to select the De-emphasis Mode according to Table 3. If the P/S pin is low, DE 0 is the
clock input for the Serial Control Mode.
De-emphasis Enable #1 or Control Data Input. If the P/S pin (pin 25) is high, DEM1 is used to
I select the De-emphasis Mode according to Table 3. If the P/S pin is low, DEM1 is the control
data input for the Serial Control Mode.
I Digital Input Format Select #0.
I Digital Input Format Select #1.
I Digital Input Format Select #2.
– Substrate Ground Pin. Substrate ground is 0 V.
I Low Level Voltage Reference Input. Normally connected to analog ground.
I High Level Voltage Reference Input. Normally connected to analog supply.
– Analog Supply. Analog supply is 5 V nominal.
– Analog Ground. Analog ground is 0 V.
O Right Channel Negative Output.
O Right Channel Positive Output.
O Left Channel Negative Output.
O Left Channel Positive Output.
O Common Voltage Output. Common voltage output is 2.6V nominal.
Parallel/Serial Control Mode Select Input. If Low, the Serial Control Mode is implemented.
I
If High, the Parallel Control Mode is selected. This pin has an internal pull-up.
I Master Clock Select #0.
