Overview

Description

Silicon Images SiI 3726 SATA Port Multiplier is 1-to-5 SATA Port Multiplier designed to provide a high performance

link between a single SATA host port and five SATA device ports. With its unique data aggregation capability and

3 Gbps serial link capability, the SiI 3726 SATA Port Multiplier is able to take full advantage of 3 Gbps host link

bandwidth and FIS-based switching host controllers by bundling together data from device ports and sending it

over the 3 Gbps host link. Additionally, the feature-rich SiI 3726 supports all the port multiplier related SATA II

extensions allowing system designers to exploit the full potential of SATA in their storage solutions.

The SiI 3726 SATA Port Multiplier supports host and device link rates of 1.5 Gbps and 3 Gbps with auto-

negotiation allowing system designers to utilize 3 Gbps host links with today’s 1.5 Gbps hard drives, and to future-

proof designs for the emergence of 3 Gbps SATA hard drives. Additionally, the SiI 3726 contains a SATA

Enclosure Management Bridge (SEMB) to pass in-band enclosure management information between the host

and an enclosure management device. Other important features include, programmable high drive capability for

backplane and external applications, asynchronous notification to eliminate the need for host polling to determine

if a device has been added or removed, and hot plug support.

The SiI 3726 is designed for optimum power, performance and price. It is based on Silicon Images industry

leading SATALink technology. It leverages much of the circuit innovation at the physical layer of Silicon Image’s

proprietary reduced-overhead Multi-layer Serial Link (MSLTM) architecture, which was pioneered and proven with

our market-leading PanelLink

® products. Silicon Image has shipped over 35 million units of PanelLink® products

for host systems and displays in the PC and the CE markets, notable for their noisy operating conditions.
