Quarter- and Half-Speed Mode
Quarter-Speed Mode (QSM) and Half-Speed Mode (HSM) allow lower sample rates while maintaining a
relatively flat noise floor in the typical audio band of 20 Hz - 20 kHz. Single-Speed Mode (SSM) will allow
lower frequency sample rates; however, the DAC's noise floor, that normally rises out-of-band, will scale
with the lower sample rate and begin to rise within the audio band. QSM and HSM corrects for most of
this scaling, effectively increasing the dynamic range of the CODEC at lower sample rates, relative to
SSM.

Digital Interface Formats
The serial port operates in standard I2S, Left-Justified or Right-Justified(DAC only) digital interface formats
with varying bit depths from 16 to 24. Data is clocked out of the ADC or into the DAC on the rising edge of
SCLK.

rial Port” on page 20
