MAX9851/MAX9853
Stereo Audio CODECs with Microphone, DirectDrive
Headphones, Speaker Amplifiers, or Line Outputs

Serial Data Output Enable (S1SDO/S2SDO)
1 = Digital audio output enabled.
0 = Digital audio output disabled.
S1SDO/S2SDO = 1 configures the MAX9851/MAX9853
to route ADC output data to the respective audio inter-
face output pin. S1SDO/S2SDO = 0 forces
SDOUTS1/SDOUTS2 low.
When both S1SDO and S2SDO are enabled, the S1
and S2 interfaces output the same data. If both outputs
are enabled, the individual interfaces may be config-
ured into different format modes as long as the pro-
grammed sample rates are identical.
Serial Data Input Enable (S1SDI/S2SDI)
1 = Digital audio input enabled.
0 = Digital audio input disabled.
S1SDI/S2SDI = 1 configures the MAX9851/MAX9853 to
perform a soft-start sequence and transfer incoming
audio data from the respective SDIN pin to the digital
filters for that interface. S1SDI/S2SDI = 0 configures the
MAX9851/MAX9853 to begin a soft-stop sequence and
then disregard incoming audio data and disable the
digital input filter path of that interface.
The SLD (register 0x00, B6) flag is set when the soft-
start or soft-stop sequence completes. The S1SDI and
S2SDI bits should be used to cleanly soft-stop signal
data prior to changing the S1MODE or S2MODE bits.
Soft-stop sequences take approximately 10ms to com-
pletely slew the volume from full scale to mute. Set the
S1SDI/S2SDI bits to enable the DACs after DACLEN
and DACREN (register 0x1B, bits B7 and B6) are set
for clean startup transitions. Likewise, clear
S1SDI/S2SDI before clearing DACLEN and DACREN.
Serial Input Mono Mix Enable (S1MNO/S2MNO)
1 = Left and right digital input signals mixed to mono
and output to the left channel.
0 = Stereo left and right digital signals maintained.
The mono signal is digitally filtered and interpolated
through the left-channel digital filter while the right-chan-
nel digital filter is shut down. The output of the left-chan-
nel filter can be routed to either or both the left and right
DACs. The stereo inputs are not attenuated before mix-
ing to mono. Clipping can occur with large input signals.
Interface S1/S2 Mode (S1MODE/S2MODE)
S1MODE/S2MODE configures the MAX9851/MAX9853
for a specific audio sampling rate on the respective digi-
tal audio interface. Set S1MODE/S2MODE to 0x1 through
0x9 to configure the interface for stereo audio operation
at the specified sample rate. Set S1MODE/S2MODE to
0xA or 0xB to configure the interface to operate in voice
mode. The secondary digital audio interface is intend-
ed to be used primarily in modes 0x1 through 0x9 as
voiceband filtering is available only on the primary serial
interface. MCLK must be 26MHz when operating in
16kHz voice mode.
