I2S
Interface
The
SMARC
‐
iMX8MM
module
uses
I2S
format
for
Audio
signals.
These
signals
are
derived
from
the
Synchronous
Audio
Interface
(
SAI
)
of
the
NXP
®
i.MX8M
Mini
processor.
The
Serial
Audio
Interface
(SAI)
implements
a
synchronous
serial
bus
interface
for
connecting
digital
audio
devices.
It
is
by
far
the
most
common
mechanism
used
to
transfer
two
channels
of
audio
data
between
devices
within
a
system.
