MIPI Soundwire I3S Analog PHY IP

High-Fidelity Audio Connectivity

Overview

COMPETITIVE ADVANTAGE

The SivaKali Tech MIPI Soundwire I3S Analog PHY IP is a highly reliable, silicon-proven IP core designed for high-performance system integration. Engineered to meet strict industry compliance standards, this core offers exceptional flexibility and ease of integration into both ASIC and FPGA designs. High-performance analog front-ends engineered for the most demanding high-speed connectivity standards. Validated on leading FPGA platforms and foundry nodes, it provides a low-risk, time-to-market advantage for developers.

COMPETITIVE ADVANTAGE

Broad Foundry Support: Silicon-proven and optimized for leading foundries including TSMC, SMIC, UMC, and GlobalFoundries.

Functional Safety Ready: Developed with ISO 26262 standards in mind, providing the reliability required for automotive and industrial missions.

Ultra-Low Power & Area: Industry-leading PPA (Power, Performance, Area) metrics achieved through meticulous circuit design and layout.

FEATURES

Fully compliant with MIPI Soundwire v1.2 and v2.0 specifications for high-fidelity, low-power audio.
Dual-Mode Audio PHY: Supports PHY1 (Intra-UI handover for power saving) and PHY2 (Scheduled handover for high bitrates).
High-speed operation: Supports Bit Clock up to 76 MHz and DDR Bus Clock up to 38 MHz.
Advanced NRZS (Non-Return-to-Zero Space) encoding/decoding for robust Control Data Channel (CDS) transmission.
Integrated Digital Bus Keeper functionality to maintain line state during handover and idle periods.
Superior Multi-drop Support: Optimized for bus topologies with up to 11 peripheral devices per master.
Programmable Electrical Controls: Real-time control of rise/fall times, drive impedance, and ramp types.
Supports advanced ramping modes: Conductance-ramp (G-Ramp) and Voltage-ramp (V-Ramp) for EMI optimization.
Integrated Weak-Drive Boost: Programmable weak0 condition impedance (7kΩ mandatory, 3.5kΩ optional) for reliable link control.
Ultra-low power "Listen" and "Sniff" modes for always-on voice trigger and microphone monitoring.
Available in leading foundry FinFET and planar nodes with high-density, low-leakage architectures.
