Soundwire Analyzer

Soundwire is a hardware interface and transport protocol developed by MIPI. It provides an expandable, simple, low-power, low-latency, dual-lead (clock and data) bus that can be used to transfer multiple audio streams such as amplifiers and microphones and embedded control commands.

Max Clock Rate:12.288MHz
