The AD2437 A2B® transceiver provides a multichannel, I2S/TDM link over distances of up to 30 m between nodes. It embeds bidirectional synchronous pulse-code modulation (PCM) data (for example, digital audio), clock, and synchronization signals onto a single-pair differential cable. A2B supports a direct point to point connection and allows multiple, daisy-chained nodes at different locations to contribute and/or consume time division multiplexed channel content.

A2B is a single main node, multiple subordinate node system where the transceiver at the host controller is the main node. The main node generates clock, synchronization, and framing for all subordinate nodes. The main A2B transceiver is programmable over a control port (I2C/SPI) for configuration and read back. An extension of the control port protocol is embedded in the A2B data stream. This allows direct access to registers and status information on subordinate transceivers, as well as I2C to I2C, SPI to I2C, or SPI to SPI communication from the host to a peripheral in a subordinate node. SPI to SPI communication between subordinate nodes can be performed directly and does not need to involve the main node.

The transceiver can connect directly to general-purpose digital signal processors (DSPs), field-programmable gate arrays (FPGAs), application specific integrated circuits (ASICs), digital microphones, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and codecs through a multichannel I2S/TDM interface. It also provides a pulse density modulation (PDM) interface for direct connection of up to four PDM digital microphones.

The transceiver supports a bus power feature, where the main node supplies voltage and current to the subordinate nodes over the same daisy-chained, single-pair wire or XLR/DMX cable as used for the communication link.

The transceiver also supports a broad spectrum of Ethernet cables in which the A2B occupies only one pair of a category (CAT) cable. This frees up the remaining CAT cable pairs for power delivery.

产品详情

The EVAL-AD2437B1MZ is an evaluation board to evaluate various peripherals of AD2437 A2B (Audio Bus) transceiver. Refer datasheet/manual to get more details about AD2437.

The EVAL-AD2437B1MZ is configured to be a Bus-Powered Sub (BPS) node. The EVAL-AD2437B1MZ can be connected to a Main Node, Local-Powered Sub (LPS) or a Bus-Powered Sub (BPS) Node. These evaluation boards are intended to be used with the SigmaStudio+ graphical development tool.

A PC host controls the AD2437 A2B main transceiver I2C/SPI signals over the USB-to-I2C/SPI bridge, the USBi(EVAL-ADUSB2EB). This allows the PC to directly discover and control an A2B network as well as to read back registers and monitor performance.

The SigmaStudio+® graphical development tool is the programming, development, and tuning software for the SigmaDSP, A2B, and Sharc processors. Familiar audio processing blocks can be wired together as in a schematic, and the compiler generates DSP-ready code and a control surface for setting and tuning parameters. This tool allows engineers with no DSP code writing experience to easily implement a DSP into their design and yet is still powerful enough to satisfy the demands of experienced DSP designers. SigmaStudio+ links with both Analog Devices evaluation boards and production designs to provide full in-circuit real-time IC control.

SigmaStudio+ includes an extensive library of algorithms to perform audio processing such as filtering, mixing, and dynamics processing, as well as basic low-level DSP functions and control blocks. Advanced record-side processing algorithms such as Enhanced Stereo Capture and wind noise detection are included in the standard libraries. Plug-in algorithms from Analog Devices and 3rd party partners can be added to SigmaStudio+'s drag-and-drop library.

Along with its graphical DSP signal flow development, SigmaStudio+ also includes other features to speed up the design cycle from product concept to release. SigmaStudio+ includes tools for intuitively setting control registers, calculating tables of filter coefficients, visualizing filter magnitude and phase responses, generating C header files, and sequencing a series of controls to ease your transition from SigmaStudio+ to system implementation on your microcontroller.

Alternatively, the EVAL-AD2437A1MZ is controllable over a SOM interface through an external DSP host device like the SC594. In the main mode, AD2437 digital audio signals interface directly to the ADAU1452 SigmaDSPTM, which provides the clock and frame sync signals to the A2B network.

The evaluation board also supports local-powered sub mode with different jumper settings, where AD2437 digital audio signals could interface to ADAU1937 audio codec or four microphones with the help of the ADAU1452. In the sub mode, AD2437 drives clock and frame sync to the ADAU1937 and ADAU1452 for transmitting or receiving data. Four digital MEMS microphones interface directly with the transceiver, they can be either downstream or upstream.
