SD；SDIO總線協(xié)議分析儀

 The SDDL1000™ SD Bus Protocol Tracer allows design engineers working with SD and SDIO technology to capture, decode and analyze bus states, command and response tokens, and to measure SD bus performance.

Offering continuous sampling the SDDL1000 can cut down the time needed to identify and resolve bus errors. The SDDL1000 can also provide sufficient debug information in real time without any need to set complex trigger events. Users can also view SD bus traffic prior to the error point to identify the source of the problem. Debug output is displayed in a straightforward but detailed format providing extensive information even for users less familiar with SD/SDIO/MMC specifications.

The SDDL1000 is a highly portable SD/SDIO logger device which can also be connected to a logic analyzer or oscilloscope to extend its capabilities.
