dspblok 21565-ETH - Analog Devices ADSP-21565 Ethernet SHARC DSP Module

The dspblok™ 21565+Ethernet is a highly integrated DSP module that incorporates an Analog Devices’ ADSP-21565 SHARC DSP operating at 1 GHz, 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 21565+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 21565+Ethernet also includes a USB transceiver. You can use the USB to upload DSP code via Danville's dspBootloader™.

The dspblok 21565+Ethernet is a specialized version of our fifth generation SHARC based products. It is a superset of the dspblok 21565. Development couldn't be easier. You can connect to an Analog Devices ICE and write your code using Analog Devices CrossCore Embedded Studio. 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.
