EVAL-AD2437A1MZ

EVAL-AD2437A1MZ is an evaluation-board to evaluate various peripherals of the AD2437 A2B (Audio Bus) transceiver. 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. This evaluation-board is 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.
