Saelig Introduces SDDL1000 SD Bus Protocol Tracer

By DE Editors

Saelig Company, Inc. has introduced the SDDL1000 SD Bus Protocol Tracer, which 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.

Designed for engineers working on SD- and SDIO-related projects, the SDDL1000 provides automatic timing violation analysis and unlimited buffer size with continuous sampling. The SDDL1000 also provides sufficient debug information in real time without the need to set complex trigger events, according to the company. SD bus traffic prior to the error points is displayed to help identify problems.

Powered from a host PC’s USB2.0 port, the SDDL1000 is only 5x3x1 inches, making it a portable device that can also be connected to a logic analyzer or oscilloscope to extend its capabilities. SD samples are streamed to the host PC and stored on the hard drive.

The SDDL1000 offers automatic protocol timing and violation detection for SD /SDIO V3.0, real-time SD bus tracing, and triggering to synchronize with digital oscilloscopes or logic analyzers. Data export functions include continuous capture for unlimited SD trace acquisition in SD/SDHC/SDXC/SDIO/SPI 1-bit and 4-bit modes. The SDDL1000 provides MMC support, SDIO Interrupt detection, CRC7/CRC16 verification and error detection, full bus decoding, and raw data mode.
