The dspblok™ 21469x2 is a highly integrated DSP module that incorporates two Analog Devices’ ADSP-21469 SHARC DSPs operating at 450 MHz, flash, EEProm and 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 21469x2 is particularly useful for high channel count systems that rely on high performance two channel data converters. For example, the dspblok 21469x2 can support an 8 input, 32 output digital audio platform since it has 16 SPORTs and 40 DAI lines available. 

The two ADSP-21469 SHARC DSPs are interconnected via link ports. Link ports allow data to be quicky transferred between the two processors.

Development couldn't be easier. You can connect to an Analog Devices HP USB ICE via JTAG on any dspblok 21469.

Alternatively, the footprint compatible dspblok 21469x2 with ICE includes a built-in Analog Devices' EZ-KIT Lite debugger. You can use the debugger with either an EZ-Kit license (free) or a full VisualDSP++ license.

Availability is late March.
