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.  
G
ENERAL FEATURES  
Three independent 3/1.5Gbps SATA ports.  
Connects 2 host ports to 1 device port.  
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  
XRS10L210. Active/passive port selector in  
XRS10L210 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  
XRS10L210 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 3/1.5Gbps rate detection/speed  
negotiation.  
Supports power down modes - Active, partial,  
slumber and power down.  
Advanced features configurable through MDIO  
bus.  
P
ORT MULTIPLIER/SELECTOR LOGIC FEATURES  
Low latency architecture.  
Supports OOB signaling for SATA applications.  
Internal OOB detectors for COMRESET/  
COMINIT and COMWAKE.  
The XRS10L210 includes enhanced features such as  
staggered HDD spin-up, power management control,  
hot plug capability and support for legacy software.  
The XRS10L210 acts as a retimer, maintaining  
independent signaling domains between the drives,  
hosts and the external interconnect.

High speed outputs with programmable pre-  
emphasis to drive long interconnects.  
Selectable high speed input equalization for  
optimum reception.

HYSICAL FEATURES  
Host and drive port speeds can be mixed and  
matched, based upon inherent data rate negotiation  
present in the SATA II specifications.

Single 1.2 V Power Supply  
The MDIO bus allows simple configuration of the

interface.

1.0 INTRODUCTION  
To summarize, the port selector functionality in the  
XRS10L210 allows replacement for expensive Fibre  
Channel drives with cost effective and high capacity  
SATA drives in enterprise class applications without  
compromising on redundancy or performance.  
The XRS10L210 is a Serial ATA II Port Selector at 3.0  
Gbps and 1.5 Gbps. It provides a failover path from  
two independent hosts to a single SATA drive and  
offers a leading solution for propagation of high data
