The Analog Devices USBi “USB Interface” (EVAL-ADUSB2EBZ) board is the interface between your PC's USB port and SigmaDSP hardware's data input pins. This interface can be used with any evaluation board which includes an External SPI/I²C header (Aardvark Header). The EVAL-ADUSB2EBZ board is capable of both SPI and I²C communication (which is user selectable) and can supply IOVDD of either 3.3V or 1.8V. The USBi is powered over the USB cable; therefore, no external power supply is required.
The EVAL-ADUSB2EBZ features USB-to-I2C and SPI conversion. The EVAL-ADUSB2EBZ provides SPI control of up to five slave devices with a low profile surface-mount USB miniature Type B connector, and it allows for plug-and-play operation. The EVAL-ADUSB2EBZ is ideal for downloading code and register settings to SigmaDSP processors and codecs with SigmaStudio. It can also be used for real-time tuning of SigmaDSP production units with SigmaStudio.
The ribbon cable and 10-pin header form a bridge to the target board to connect the communications signals to the target IC. The ribbon cable also carries 5V power from the USB hub, which can be used to power the target board if desired. The USBi can be used to control SigmaDSP systems in real time via SigmaStudio, and is capable of programming an EEPROM in self-boot systems. It is an ideal solution for in-circuit programming and tuning of prototype systems. The USBi only supports USB 2.0 interfaces; the USBi will not work with PCs that only support USB Version 1.0 and USB Version 1.1.
