CS5368

Stand-Alone Mode

CLKMODE

CLKMODE (Input) Setting this pin HIGH places a divide-by-1.5 circuit in the MCLK

path to the core device circuitry.

DIF1, DIF0

37, 38 DIF1, DIF0 (Input) - Inputs of the audio interface format.

M1, M0

39,40 Mode Selection (Input) - Determines the operational mode of the device.

MDIV

MCLK Divider (Input) Setting this pin HIGH places a divide-by-2 circuit in the MCLK

path to the core device circuitry.

Control Port Mode

CLKMODE

CLKMODE (Input) This pin is ignored in Control Port Mode and the same functionality

is obtained from the corresponding bit in the Global Control Register. Note: Should be

connected to GND.

AD1/CDIN

I²C Format, AD1 (Input) - Forms the device address input AD[1].

SPI Format, CDIN (Input) - Becomes the input data pin.

AD0/CS

I²C Format, ADO (Input) - Forms the device address input AD[0].

SPI Format, CS (Input) - Acts as the active low chip select input.

SCL/CCLK

I²C Format, SCL (Output) - Acts as the serial clock output from the CS5368.

SPI Format, CCLK (Output) - Acts as the serial clock output from the CS5368.

SDA/CDOUT

I²C Format SDA (Input/Output) - Acts as an input/output data pin.

SPI Format CDOUT (Output) - Acts as an output only data pin.

MDIV

MCLK Divider (Input) This pin is ignored in Control Port Mode and the same function-

ality is obtained from the corresponding bit in the Global Control Register.

Note: Should be connected to GND.
