SII3531 Datasheet, PDF (1/2 Pages) Silicon image – SteelVine™ Host Controller

Product Brief
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.
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.
