EVAL-AD2437B1NZ

EVAL-AD2437B1NZ is an evaluation-board to evaluate various peripherals of the AD2437 A2B (Audio Bus) transceiver. The board is configured to be a Bus-Powered Sub (BPS) node. The EVAL-AD2437B1NZ can be connected to a main node, Local-Powered Sub (LPS) or a Bus-Powered Sub (BPS) node. This evaluation-board is 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; USBi(EVAL-ADUSB2EB). This allows SigmaStudio+ 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.
