Better Serial ATA (SATA) and SAS Measurements: 6 Hints

Application Notes

Serial ATA (SATA) and Serial Attached SCSI (SAS) are data-transfer technologies for moving data to and from storage devices. The Serial ATA International Organizations (SATA-IO) and Serial Attached SCSI (SAS) T10 standard committees have both released specifications to provide support for 6 Gbps data transfer and will soon be releasing higher data rates up to 12 Gbps. As the speed increases, the validation effort increases exponentially as well. In order for the storage interface to function properly, its signal integrity performance must meet certain minimum requirements. Signal integrity is the key to system interoperability, or the guarantee that products from different vendors will integrate well, when used together. Failures in signal integrity are correlated to other failures, including marginal timing relationships, protocol violations, jitter issues, and errors from other buses. This application note will highlight a few of the methods that can help you characterize, validate and debug your designs faster.
