SERIAL ATA II: PORT MULTIPLIER / PORT SELECTOR

REV. 1.05

JANUARY 2009

FEATURES

independent hosts, the XRS10L240 offers a leading

solution for propagation of high data rate Serial ATA

products in a wide variety of applications. The

integration of Serial ATA PHY links, a variety of digital

logic capabilities, rate adjust FIFOs, integrated low-

cost clock oscillator support, test and loopback

features is achieved in a low cost and lower power

implementation.

•

ENERAL FEATURES

Six independent 3/1.5Gbps SATA ports.

Connects 2 host ports to 4 device ports.

•

Supports 3/1.5Gbps rate detection/speed

negotiation.

The port selector function is used when dual hosts,

such as I/O controllers, must access single-port disk

drives in high availability storage subsystems where

redundancy and load sharing are important. The

outputs from the I/O controllers are multiplexed to a

Serial ATA drive through the port selector block of the

XRS10L240. Active/passive port selector in

XRS10L240 allows two different host ports to connect

to the same target in order to create a redundant path

to that target. In combination with RAID, the

XRS10L240 allows system providers to build fully

redundant solutions. This avoids the presence of a

single point of failure, and enables a fail-over path in

the case of host failure.

•

Supports power down modes - Active, partial,

slumber and power down.

Advanced features configurable through MDIO

bus.

ORT MULTIPLIER/SELECTOR LOGIC FEATURES

•

Low latency architecture.

•

Supports OOB signaling for SATA applications.

Internal OOB detectors for COMRESET/

COMINIT and COMWAKE.

I/O FEATURES

•

High speed outputs with programmable pre-

emphasis to drive long interconnects.

This port multiplier function is used when one active

host has to communicate with multiple SATA drives.

The XRS10L240 supports up to 4 SATA drives and

utilizes the full bandwidth of the host connection.

•

Selectable high speed input equalization for

optimum reception.

Compliant with SATA Gen-2i

specification.

Gen-2m

The XRS10L240 includes enhanced features such as

staggered HDD spin-up, power management control,

hot plug capability and support for legacy software.

Enables reliable data transmission over 1 meter

or more of FR-4 and 4 meters or more of The XRS10L240 acts as a retimer, maintaining

unequalized copper cable.

independent signaling domains between the drives,

hosts and the external interconnect.

•

Selectable spread spectrum clocking (SSC) to

reduce EMI.

The high-speed serial input feature: selectable

equalization and the high-speed serial output feature:

programmalbe pre-emphasis can be used to

compensate for ISI (Inter-Symbol Interference) and

increase maximum cabling distances.

•

HYSICAL FEATURES

CMOS 0.13 Micron Technology

Single 1.2 V Power Supply

XRS10L240 meets tight jitter budgets in SATA

applications. Exar's serial I/O technology enables

reliable data transmission over 1 meter or more of

FR-4 and 4 meters or more of unequalized copper

cable.

-40°C to 85°C Industrial Temperature Range

No heatsink or airflow required

100-Pin LQFP Package

Host and drive port speeds can be mixed and

matched, based upon inherent data rate negotiation

present in the SATA II specifications.

1.0 INTRODUCTION

The XRS10L240 provides the combined advantages

of the Serial ATA II Port Selector and Port Multiplier

implementations for Serial ATA II systems at 3.0

Gbps and 1.5 Gbps. Combining the capability to

address four Serial ATA devices from one external

link with support for a failover path from two

The MDIO bus allows simple configuration of the

XRS10L240 when needed. Receive equalization,

transmit amplitude and pre-emphasis and SSC

control are all configurable via the 2-wire MDIO

interface.
