[Shenzhen, China] — With the full-scale arrival of the era of smart cockpits and software-defined vehicles (SDVs), in-vehicle audio systems are undergoing unprecedented transformation. As a leading global distributor of electronic components, Shenzhen Mingjiada Electronics Co., Ltd. (hereinafter referred to as “Mingjiada Electronics”) announced that it is actively supplying Analog Devices’ (ADI) full line of in-vehicle audio solutions, including the latest A2B 2.0 automotive audio bus chip and high-performance SigmaDSP audio processors, to help automakers and Tier 1 suppliers create high-fidelity, low-latency audio experiences for smart cockpits.
Seizing Market Opportunities: ADI A2B 2.0 Enters Mass Production
To meet the demand for high-bandwidth audio transmission in next-generation smart cockpits, ADI has recently officially launched and commenced mass production of A2B 2.0 (ADAA245x series) technology. As the dominant technology in the in-vehicle audio networking market [Source: THE ELEC], A2B 2.0 represents a significant leap forward compared to the 1.0 version.
Leveraging Mingjiada Electronics’ robust supply chain channels, customers can now gain priority access to this latest technology. The core advantages of A2B 2.0 include:
A Quantum Leap in Bandwidth: Full-duplex data rates have been increased to 98.3 Mbps—four times that of the previous generation—supporting uplink and downlink transmission of up to 119 audio channels.
Lossless Audio and Noise Cancellation: High bandwidth enables the simultaneous operation of personalized zone-based sound fields, Road Noise Cancellation (RNC), and lossless high-resolution audio.
Simplified Architecture and Low Latency: Continuing the single-pair twisted-pair daisy-chain architecture, it reduces wiring harness weight and cost by up to 75% while maintaining a deterministic ultra-low latency of 62 microseconds, ensuring effective active noise cancellation.
Seamless Ethernet Integration: New OASPI Ethernet tunneling capabilities allow for easy integration with modern in-vehicle backbone networks (in-vehicle Ethernet), supporting software-defined vehicle architectures.
Compatibility: Backward compatible with existing A2B 1.0 wiring harnesses and connectors; system performance upgrades can be achieved simply by replacing the chip.
