Differential Analog (Inputs) - Audio signals are presented differently to the delta sigma modula-
tors via the AIN+/- pins.
GND

16,17
18,19
29,32
43,44
45,46
Ground (Input) - Ground reference. Must be connected to analog ground.
VA
4,9
Analog Power (Input) - Positive power supply for the analog section.
REF_GND
5
Reference Ground (Input) - For the internal sampling circuits. Must be connected to analog
ground.
FILT+
6
Positive Voltage Reference (Output) - Reference voltage for internal sampling circuits.
VQ
7
Quiescent Voltage (Output) - Filter connection for the internal quiescent reference voltage.
VX
20
Crystal Oscillator Power (Input) - Also powers control logic to enable or disable oscillator cir-
cuits.
XTI
XTO
21
22
Crystal Oscillator Connections (Input/Output) - I/O pins for an external crystal which may be
used to generate MCLK.
MCLK
23
System Master Clock (Input/Output) - When a crystal is used, this pin acts as a buffered 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.
LRCK/FS
24
Serial Audio Channel Clock (Input/Output)
In IS mode, Serial Audio Channel Select. When low, the odd channels are selected.
In LJ mode, Serial Audio Channel Select. When high, 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.
SCLK
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.
TSTO
26
Test Out (Output) - Must be left unconnected.
SDOUT2
27
Serial Audio Data (Output) - Channels 3,4.
VLS
28
Serial Audio Interface Power - Positive power for the serial audio interface.
SDOUT1/TDM
30
Serial Audio Data (Output) - Channels 1,2.
TDM
31
TDM - TDM is complementary TDM data.
VD
33
Digital Power (Input) - Positive power supply for the digital section.
VLC
35
Control Port Interface Power - Positive power for the control port interface.
OVFL
36
Overflow (Output, open drain) - Detects an overflow condition on both left and right channels.
RST
41
Reset (Input) - The device enters a low power mode when low.
