Product Brief
SteelVine^™ Device Bridge
Serial ATA (SATA) to Parallel ATA device bridge
The SiI3811 is a single-chip Serial ATA to Parallel ATA device bridge solution that com-
bines the transport, link, and PHY layers of Serial ATA with a Parallel ATA interface. The
SiI3811 enables manufacturers to connect widely available, low-cost Parallel ATA devices
like DVD/CD-ROM and hard disk drives to industry standard Serial ATA controllers such
as those available in the PC’s south bridge. As a member of Silicon Image’s SteelVine
family of Serial ATA products, the SiI3811 has undergone extensive interoperability testing
and provides the industry’s most robust device bridge solution.
The SiI3811 supports Serial ATA transfer rates of
1.5 Gbps (150 MB/s) with its on-board serializer /
de-serializer. It features an ultra ATA/133 Parallel
ATA port to interface with devices such as hard
disk and DVD/CD-ROM drives. The SiI3811
accepts Serial ATA commands from the host’s
Serial ATA interface, decodes the commands and
converts them to parallel ATA device commands.
Device responses through the parallel ATA bus are
deciphered, processed, converted to the Serial ATA
protocol and sent to the SATA host controller.
At the physical layer, the SiI3811 leverages much
of the circuit innovation of Silicon Image's propri-
etary reduced overhead Multi-Layer Serial Link
(MSL™) architecture, pioneered and proven
through the company’s market-leading HDMI and
SATA products. MSL technology is a multi-layer
approach to providing robust, cost-effective,
multi-gigabit semiconductor solutions on a single
chip for high-bandwidth applications.
