Pin Description
DAC Serial Audio Data Input ( Input ) - Input for two’s complement serial audio data.
DAC Serial Clock (Input/Output) - Serial clock for the DAC serial audio interface.
DAC Left Right Clock ( Input / Output ) - Determines which channel, Left or Right, is currently active on
the DAC serial audio data line.
Digital Power ( Input ) - Positive power supply for the digital section.
Digital Ground ( Input ) - Ground reference. Should be connected to digital ground.
Control Port Power ( Input ) - Determines the required signal level for the control port.
Serial Control Port Clock ( Input ) - Serial clock for the serial control port. Requires an external pull-up
resistor to the logic interface voltage in I
Serial Control Data ( Input/Output ) - SDA is a data I/O line in I
resistor to the logic interface voltage, as shown in the Typical Connection Diagram. CDOUT is the output
data line for the control port interface in SPI mode.
Address Bit 1 (I
the input data line for the control port interface in SPI mode.
Address Bit 0 (I
is the chip select signal in SPI mode.
Interrupt (Output ) - The CS42428 will generate an interrupt condition as per the Interrupt Mask register.
See “Interrupts” on page 28 for more details.
