MIPI Alliance provides two interfaces, MIPI SLIMbus(R) and MIPI SoundWire, which simplify the integration of multiple audio components in a wide range of devices, from smartphones to PCs to automobiles. Engineers can use the interfaces to meet customers’ increasingly sophisticated expectations for audio quality and audio-based user interactions. The interfaces also minimize costs, pin count and power consumption.
MIPI SLIMbus and MIPI SoundWire are developed by the MIPI Audio Working Group.
Both MIPI SLIMbus and MIPI SoundWire are implemented on CMOS I/Os. Each interface uses a two-wire hardware and transport interface, and supports embedded control and data channels, multiple clocks, isochronous and asynchronous modes, PCM and PDM formats, as well as embedded interrupts, wake-up and clock-stop.
A summary of the features and the respective capabilities of the two specifications can be found in this Technical Brief.
