1. PIN DESCRIPTION - PCM DATA MODE

RST

Reset (Input) - Powers down device and resets all internal registers to their default settings.

Logic Power (Input) - Positive power for the digital input/output.

SDATA

Serial Audio Data (Input) - Input for two’s complement serial audio data.

SCLK

Serial Clock (Input/Output) - Serial clock for the serial audio interface.

LRCK

Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently active on the

serial audio data line.

MCLK

Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters.

FILT+

Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits.

CMOUT

Common Mode Voltage (Output) - Filter connection for internal quiescent voltage.

AMUTEC

BMUTEC

Mute Control (Output) - The Mute Control pin goes high during power-up initialization, reset, muting,

power-down or if the master clock to left/right clock frequency ratio is incorrect.

AOUTB-

AOUTA+

AOUTA

Differential Analog Output (Outputs) - The full scale differential analog output level is specified in the

Analog Characteristics specification table.

AGND

Ground (Input)

Analog Power (Input) - Positive power for the analog section.

Control Port Mode Definitions

Mode Selection (Input) - This pins should be tied to GND level during control port mode.

SCL/CCLK

Serial Control Port Clock (Input) - Serial clock for the serial control port.

SDA/CDIN

Serial Control Data (Input/Output) - SDA is a data I/O line in I2C mode. CDIN is the input data line for

the control port interface in SPI mode.

AD0/CS

Address Bit 0 (I2C) / Control Port Chip Select (SPI) (Input/Output) - AD0 is achipaddress pininI2C

mode; CS is the chip select signal for SPI format.

Stand-Alone Mode Definitions

Mode Selection (Input) - Determines the operational mode of the device.
