A2B Audio Bus Solutions
A2BTM is a high bandwidth, bidirectional digital audio bus. it is capable of transporting I2S/TDM/PDM data and SPI/I2C control information with clock and power (up to 50W), using a single, 2-wire UTP cable over distances up to 30 m between nodes and 300 m over the entire daisy chain (up to 17 nodes). It can be used as its own network with embedded sub-networks, or as an endpoint transport bus used in combination with other, longer distance protocols. The clock is synchronous on all nodes in a single A2B network. The audio at all nodes is synchronized.
Value and Benefits
Analog Devices’ A2B digital audio bus solutions offer a broad array of full-featured evaluation systems to quickly prototype an A2B network and facilitate early system proof of concept, test, verification, and debug. The A2B solution eliminates the need for an expensive microcontroller and external memory. The transceiver’s ability to provide power to remote nodes over the same, low-cost UTP cable removes the need for a local power supply at each bus-powered subordinate node. A2B is configurable to 44.1 kHz or 48 kHz frame rate, up to TDM32, and up to a 50 Mbps bandwidth.
Configures and scales seamlessly for quick prototyping
Offers superior audio quality while reducing system cost and weight
Features deterministic and sub-50 µs latency
