SmartDV’s SAS Initiator IP is a silicon-proven, fully featured Serial Attached SCSI solution purpose-built for SoC designs requiring high-performance, reliable storage connectivity across enterprise, data center, and high-performance embedded applications. Fully compliant with SPL-5 (INCITS 554-2023) and SAS-4.1 (INCITS 567-2023), it delivers complete initiator-side SAS functionality supporting data transfer rates from 1.5 Gbps through 22.5 Gbps across SSP, SMP, and STP protocols, with full SATA tunneling support at 1.5, 3, and 6 Gbps — providing a proven, production-ready storage interface foundation for the most demanding HBA and storage controller designs.
Designed to address the full breadth of SAS initiator requirements, the IP implements the complete PHY, link, and transport layer stack including OOB sequence generation, SNW-3 capability negotiation, spread spectrum clocking, forward error correction, interleaved SPL packet mode, and SAS Dword and Packet mode operation. Its support for narrow and wide ports, BMC encoding, 8b/10b encode/decode, complete K and D code validity checking, and DMA and PIO commands gives storage SoC teams a production-tested, spec-complete SAS initiator that handles the full range of SAS and SATA storage device types with maximum protocol compliance.
Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its native 32-bit PHY interface, configurable parallel interface widths, and clean host interface enable fast integration and confident design bring-up across a wide range of enterprise storage process nodes and target applications.
