MIPI SoundWire Manager IP

Design IP

Overview

SmartDV’s MIPI SoundWire Manager IP offers a streamlined, low-power interface solution for high-fidelity audio integration across mobile, automotive, and consumer applications. Compliant with the latest MIPI SoundWire 1.3 specification, it facilitates efficient, synchronized audio data transfer over a minimal pin interface, reducing complexity while maximizing performance.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. The IP supports features such as multi-device communication, bus arbitration, dynamic device discovery, and programmable frame structures, making it ideal for scalable and robust audio architectures.

Benefits

Scalable Multi-Device Support – Connects and manages up to 11 peripheral devices with flexible configuration options
High-Bandwidth Architecture – Supports up to 8 data lanes with modified-NRZI data encoding for efficient transmission
Flexible Configuration – User-programmable PDI count, command FIFO depth, data lane count, and port memory sizes
Advanced Clock Management – Implements clearly demarked clock domains and extensive clock gating for power efficiency
Robust Bus Control – Includes special internal registers per device and an arbitration mechanism for port access
Reliable Data Handling – Provides limited retransmission, frame-layer interleaving of control and data spaces, and flow control mechanisms
Comprehensive Error Management – Detects and reports parity, synchronization, and CRC errors
Collision and Protocol Support – Detects message and data channel collisions and supports user-defined protocol implementations
Accurate Synchronization – Provides bi-directional DATA line, unidirectional CLK line, and device enumeration for precise timing
