Overview

Product Details

The EVAL-AD2437A1MZ is an evaluation board to evaluate various peripherals of the AD2437 A2B (Audio Bus) transceiver. Refer to the datasheet/manual to get more details about the AD2437.

The EVAL-AD2437A1MZ can be configured to be a Main Node or Local-Powered Sub (LPS) Node. The EVAL-AD2437A1MZ 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.

In the default configuration (Main Mode), this evaluation board provides A2B main node functionality for an A2B network.

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

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.
