I. Core Supplied Products

1. Master and slave transceivers

AD2428W series

Function: Supports master/slave node configuration, integrates I2S/TDM/PDM interfaces, can cascade up to 10 slave nodes, with a single node spacing of up to 15 meters and a total link length of 40 meters.

Advantages: Reduces local power reliance through phantom power (up to 300mA), and features built-in EMI optimization and diagnostic functions, meeting strict automotive-grade EMC requirements.

Applications: Multi-microphone array, active noise cancellation system, in-vehicle communication module.

AD2426W/AD2427W series

Positioning: High cost-performance version, focusing on slave operation and PDM microphone connection, suitable for entry-level in-car audio systems.

2. Enhanced Transceiver (AD243x Series)

AD2435WCCPZY21-RL:

Innovation points: Supports a total cable length of 80 meters, with the power transmission capacity increased to 50W, capable of driving high-power peripheral devices (such as high-power speakers).

Application scenarios: Distributed audio systems, intelligent tuner modules.

Ii. Typical Application Scenarios

Intelligent cockpit audio system

Multi-zone independent audio effects: Through the A2B® bus, independent audio streams for different audio zones are distributed to ensure that the driver's navigation prompts and rear entertainment do not interfere with each other.

Enhanced voice interaction: Integrated with 4 PDM microphone inputs, it supports high-precision voice wake-up and noise reduction, improving the response accuracy of the intelligent assistant.

2. Active noise reduction and road noise elimination

ANC/RNC system: It collects noise signals in real time through an acceleration sensor and an A2B® microphone array, and generates reverse sound waves in combination with a SHARC® DSP, reducing the noise inside the vehicle by more than 20dB.

3. In-vehicle communication and infotainment

eCall Emergency Call: The low latency feature of A2B® ensures the rapid transmission of voice data in case of an accident, meeting the requirements of the EU eCall regulations.

High-definition audio transmission: Supports 24-bit/192kHz lossless audio quality, compatible with high-end car audio brands (such as Harman, Bose).
