Transceivers boost in-vehicle audio bandwidth

ADI’s ADAA245x series of A²B 2.0 Automotive Audio Bus transceivers delivers 4× higher bus bandwidth (98.3 Mbps full-duplex) than A²B 1.0 devices. Now in production, the transceivers handle up to 119 upstream and downstream audio channels for advanced automotive audio systems, enabling high-definition audio transport across ECU networks.

The ADAA2457 supports Ethernet data tunneling via an Open Alliance SPI (OASPI) interface. All ADAA245x devices are compatible with existing A²B 1.0 cable and connector infrastructure and enable A²B 1.0 branching via device-specific I²S, I²C, and SPI interfaces. The ADAA2455 operates as a sub-node transceiver, while the ADAA2456 and ADAA2457 can be configured as main or sub-nodes.

According to ADI, the transceivers achieve up to 30% system cost reduction through increased functional integration and reduced external circuitry and component count. They also provide low, deterministic latency of 62 µs and are built for straightforward integration.
