dspblok 21469 - Analog Devices ADSP-21469 SHARC DSP Module

The dspblok™ 21469 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. 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").

The dspblok 21469 is also available in an extended temperature (-ET) version. The operating temperature for this variation is -40 to +85 C, with a maximum core clock of 400MHz.

The dspblok 21469 is supported by a family of dspblok power supplies, data converter modules, and digital I/O modules.

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.
