Serial Data Inputs
Digital Audio Input Port
The CS44600 interfaces to an external Digital Audio Processor via the Digital Audio Input serial port, the
DAI serial port. The DAI port has 3 stereo data inputs with support for I²S, left-justified and right-justified
formats. The DAI port operates in slave operation only, where DAI_LRCK, DAI_SCLK and DAI_MCLK are
always inputs. The signal DAI_LRCK must be equal to the sample rate, Fs and must be synchronously
derived from the supplied master clock, DAI_MCLK. The serial bit clock, DAI_SCLK, is used to sample
the data bits and must be synchronously derived from the master clock.
DAI_SDIN1, DAI_SDIN2, and DAI_SDIN3 are the serial data input pins supplying the associated internal
PWM channel modulators. The serial data interface format selection (left-justified, right-justified, I²S, one
line mode, or TDM) for the DAI serial port data input pins is configured using the appropriate bits in the
register
ment binary form with the MSB first in all formats.
When operated in One Line Data Mode, 6 channels of PWM data are input on DAI_SDIN1. In TDM mode,
all 6 channels are multiplexed onto the DAI_SDIN1 data line.
locations.
The DAI digital audio serial ports support 6 formats with varying bit depths from 16 to 24 as shown in
