Description
OUTPUT_LRCLK Polarity. When this bit is set to 0, the left-channel data is clocked when OUTPUT_LRCLK is
low and the right-channel data is clocked when OUTPUT_LRCLK is high. When this bit is set to 1, the right-
channel data is clocked when OUTPUT_LRCLK is low and the left-channel data is clocked when
OUTPUT_LRCLK is high.
OUTPUT_BCLK Polarity. This bit controls on which edge of the bit clock the output data is clocked. Data
changes on the falling edge of OUTPUT_BCLK when this bit is set to 0 and on the rising edge when this bit is
set to 1.
Master/Slave. This bit sets whether the output port is a clock master or slave. The default setting is slave; on
power-up, the OUTPUT_BCLK and OUTPUT_LRCLK pins are set as inputs until this bit is set to 1, at which time
they become clock outputs.
OUTPUT_BCLK Frequency (Master Mode Only). When the output port is being used as a clock master, these
bits set the frequency of the output bit clock, which is divided down from an internal 1024 × f
(49.152 MHz for a f

OUTPUT_LRCLK Frequency (Master Mode Only). When the output port is used as a clock master, these bits set
the frequency of the output word clock on the OUTPUT_LRCLK pins, which is divided down from an internal
1024 × f

Frame Sync Type. This bit sets the type of signal on the OUTPUT_LRCLK pins. When this bit is set to 0, the
signal is a word clock with a 50% duty cycle; when this bit is set to 1, the signal is a pulse with a duration of
one bit clock at the beginning of the data frame.
TDM Enable. Setting this bit to 1 changes the output port from four serial stereo outputs to a single
8-channel TDM output stream on the SDATA_OUT0 pin (MP6).
MSB Position. These three bits set the position of the MSB of data with respect to the LRCLK edge. The data
output of the ADAU1701 is always MSB first.

Output Word Length. These bits set the word length of the output data-word. All bits following the LSB are
