steelvine ? host controller pci express to serial ata gen ii host controller built on the proven architecture of silicon image's industry-leading host controllers, the SII3531 is a single-lane pci express to single-port serial ata (sata) ii host controller that offers best in class sata price/performance and is both flexible and robust enough for today's demanding storage applications. applications ? pc motherboards ? expresscard applications ? server motherboards ? embedded applications key features ? latest generation sata ii (3 gb/s) ? small 48-pin qfn package ? port multiplier support with fis based switching ? software raid 0, 1, 5, 10 support product brief the x1 pci express interface integrates with the latest motherboard architectures and provides a cost effective way for manufacturers to differen- tiate their motherboards with an esata port. the SII3531 supports all serial ata ii features, including 3.0 gbps sata ii transfer speeds, native command queuing, port multipliers with fis-based switching, programmable output sig- nal swing strengths for longer external cables or extended backplanes, hot plugging, enclosure management and atapi device support. the SII3531 supports soft raid 0, 1, 5 and 10 when connected to port multiplier such as the sii3726. users familiar with the sii3124 or sii3132 will recognize the SII3531 common driver structure. end-users will appreciate the SII3531 windows and linux drivers for both raid and non- raid operations. the SII3531 leverages much of the circuit inno- vation at the physical layer of silicon image's proprietary reduced overhead multi-layer serial link (msl ? ) architecture, pioneered and proven through its panellink products and extended to the satalink and fibre channel serdes storage products. msl technology is a multilayer approach to providing cost-effective, multi-giga- bit semiconductor solutions on a single chip for high-bandwidth applications.
