Analog Devices launches next-gen in-vehicle audio experience. Analog Devices has announced that it's A[2]B 2.0 (Automotive Audio Bus) is now fully released to production. As the next evolution of ADI's A[2]B technology, A[2]B 2.0 is designed to help automotive OEMs (original equipment manufacturers) and Tier 1 suppliers deliver richer in-cabin audio experiences through greater bandwidth and Ethernet integration, while preserving the low-latency, simple architecture that has defined A[2]B for years. Over the past decade, A[2]B has been broadly adopted in the automotive industry, with hundreds of millions of nodes on the road from over 35 automotive manufacturers, establishing a strong foundation for the next evolution of the technology. Built for applications where low and deterministic latency is a key system requirement, A[2]B was designed to support demanding use cases such as road-noise cancellation and in-car communications through a simple, flexible, and cost-effective approach to audio connectivity. Its single main, multiple sub-node daisy-chain architecture reduces wiring complexity and associated costs by up to 75%. The straightforward architecture with zero software overhead also lowers overall development time and investment for OEMs and Tier 1 suppliers. A[2]B's momentum is reinforced by an ecosystem that spans OEMs, silicon partners, and original design manufacturers (ODMs), supported by an expansive set of development and test tools that accelerate time-to-market. As vehicles transition to software-defined architectures, in-cabin features are increasingly delivered and improved through software, raising the bar for deterministic, high-bandwidth connectivity that can integrate cleanly with modern in-vehicle networks. As in-cabin technology becomes a key differentiator for automakers, expectations for premium audio and infotainment continue to rise, ultimately driving demand for higher bandwidth, advanced connectivity, and seamless integration with today's vehicle networks. A[2]B 2.0 expands the A[2]B platform with higher bandwidth and Ethernet compatibility, while maintaining the low-latency, simple architecture customers rely on. Key capabilities include: - Performance and scalability o 4x bandwidth increase (up to 98.3Mbps, full duplex) to support more advanced in-vehicle audio architectures. o Support for up to 119 upstream and 119 downstream audio channels to enable advanced automotive audio system configurations. - Ethernet compatibility o Ethernet data tunnelling via the industry-standard Open Alliance SPI (OASPI) interface, for enhanced connectivity and flexibility. - Efficiency, latency, and upgrade path o Up to 30% system cost reduction enabled through increased functional integration and reduced external circuitry and components o Low and deterministic latency, including a noted 62μs low latency and an architecture designed for straightforward integration. o Compatibility with existing A[2]B 1.0 cabling and connector infrastructure, supporting a simple upgrade path. Additionally, the ADAA245x devices can easily branch to A2B 1.0 networks, maximising re-use of existing modules.

Raltron VCXO targets ultra low Phase Noise reference clocks for high performance timing and RF systems. Raltron, a global leader in high-performance frequency control components, wireless antenna products, and high-quality audio components, announces the VC8620D-D3-20-100.000-4-5, a low phase noise 100 MHz sine-wave voltage controlled crystal oscillator (VCXO) optimized for satellite payloads, ground stations, test & measurement, and high-performance synthesizer reference clock architectures. Delivering both excellent close-in phase noise and long-term stability, the new VCXO is ideal for LO, PLL, and clock distribution schemes where every decibel of noise and jitter directly impacts link budgets and system resolution. The VC8620D-D3-20-100.000-4-5 provides a nominal 100.000 MHz output to drive mixers, PLL ICs, and clock buffers without additional amplification. With low spurious levels of -80 dBc and no sub-harmonics, designers can maintain clean spectral masks in dense RF environments typical of satellite transponders and multi-band synthesizers. Engineered as a precision reference, the VCXO is well-suited for long-life satellite ground infrastructure and mission-critical RF systems, helping maintain narrow channel spacing and stable LO plans over the life of the platform. The low-noise profile of the VC8620D-D3-20-100.000-4-5 supports low-jitter PLLs, high-order modulation schemes, and high dynamic range receivers where phase noise directly impacts EVM and SNR. Housed in a rugged 14.3 mm x 9.0 mm package with a maximum 5.6 mm height and gold-plated contacts on an FR5 board, the VCXO integrates smoothly onto dense RF boards, synthesizer modules and instrumentation backplanes. "With this low phase noise 100 MHz VCXO, we set out to give our customers the spectral purity, stability, and long-term reliability they need to unlock the full performance of their RF front ends and PLL architectures" said Sasha Wolloch, President of Raltron. The VC8620D-D3-20-100.000-4-5 VCXO is available now for use in satellite communications equipment, RF synthesizers, and other phase-noise-critical timing applications.
