The dspblok™ 21489 + Ethernet is a highly integrated DSP module that incorporates an Analog Devices’ ADSP-21489 SHARC DSP operating at 400 MHz, flash, EEProm, 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 21489+Ethernet includes a Wiznet W5100 Ethernet transceiver operating at 100Mb/s. Each module has a unique MAC address preassigned. The transceiver manages the TCP/IP stack so that the DSP is largely unburdened. You just add magnetics and a connector. Since the magnetics are external, you can also create Power over Ethernet (POE) targets for smart sensor applications.
The dspblok 21489+Ethernet also includes a high-speed USB transceiver. You can use the USB to upload DSP code via Danville's dspBootloader™.
The dspblok 21489+Ethernet is a specialized version of our fourth generation SHARC based products. It is a superset of the dspblok 21489. 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.
