MIPI Soundwire Controller IP

OverviewFeaturesRequest Datasheet


The MIPI SoundWire is an interface specification that enables bi-directional digital Audio communication between a Master and one or more slave devices and among slave devices. It is optimized for mobile and Mobile inspired systems. It can co-exist with MIPI-Compliant and non-MIPI-Compliant devices.
MIPI SoundWire is low-complex, low-power, low-latency interface that supports multichannel data. Being low gate count enables it to be adopted it into smaller components like microphones and amplifiers.
L&T’s SoundWire Master is used in any master controllers like Amplifiers or processors to transfer or receive audio data from one of the SoundWire slaves, like the one connected to a microphone or a speaker. Likewise L&T’s SoundWire Slave is a full SoundWire standard compliant slave that can do a slave to slave communication according to the device component connected to it.
