*As of 02/07/2022, the dspblok 21469+USB is currently on a strict allocation basis for our current customers. Please contact us to discuss a suitable replacement for this DSP Module*
The dspblok™ 21469+USB is a highly integrated DSP module that incorporates an Analog Devices’ ADSP-21469 SHARC DSP operating at 450 MHz, flash, EEProm, 1Gb DDR2 memory, and a switching power supply to support the core voltage requirements.
A high-speed USB 2.0 interface based on an FTDI FT2232H provides a convenient way to upload your application code via Danville's dspBootloader™. The USB port is also available for your application with driver support for many operating systems including COM port emulation. All the connections are brought out to standard 2mm dual row header footprints. The board is only 60mm x 60mm (2.36" x 2.36").
Development couldn't be easier. You can connect to an Analog Devices ICE using a Danville JTAG Adapter. Analog Devices has two development packages available: CrossCore Embedded Studio or Visual DSP++.
If you are starting a new project or designing your own target, you may want to use the dspblok Development Board. This board is convenient as a starting place to connect other development boards (data converters and I/O). It includes a power supply and computer connections to get you started.
