Differential Analog (Inputs) - Audio signals are presented differently to the delta
sigma modulators via the AIN+/- pins.
3,8
10,19 Ground (Input) Ground reference. Must be connected to analog ground.
29,32
4,9 Analog Power (Input) - Positive power supply for the analog section
7
Quiescent Voltage (Output) - Filter connection for the internal quiescent reference
voltage.
20 XTAL Power
28 Serial Audio Interface Power - Positive power for the serial audio interface.
33 Digital Power (Input)- Positive power supply for the digital section/
35 Control Port Interface Power - Positive power for the control port interface.
5 Reference Ground (Input) - For the internal sampling circuits.
6
Positive Voltage Reference (Output) - Reference voltage for internal sampling cir-
cuits.
21 Crystal Oscillator Connections (Input/Output) - I/O pins for an external crystal which
22 may be used to generate MCLK.
System Master Clock (Input/Output) - When a crystal is used, this pin acts as a buff-
23
ered MCLK Source (Output). When the oscillator function is not used, this pin acts as
an input for the system master clock. In this case, the XTI and XTO pins must be tied
low.
Serial Audio Channel Clock (Input/Output)
In I²S mode Serial Audio Channel Select. When high, the odd channels are selected.
24 In LJ mode Serial Audio Channel Select. When low, the odd channels are selected.
In TDM Mode a frame sync signal. When high, it marks the beginning of a new frame of
serial audio samples. In Slave Mode, this pin acts as an input pin.
25
Main timing clock for the Serial Audio Interface(Input/Output). During Master Mode,
this pin acts as an output, and during Slave Mode it acts as an input pin.
26 Serial Audio Data (Output) Channels 7,8.
27 Serial Audio Data (Output) Channels 3,4.
30 Serial Audio Data (Output) Channels 1,2.
31 Serial Audio Data (Output) Channels 5,6.
36
Overflow (Output, open drain) - Detects an overflow condition on both left and right
channels.
41 Reset (Input) - The device enters a low power mode when low.
