FEATURES

GENERAL - SATA AND SAS

•

Four bi-directional 2:1 SATA or

SAS multiplexer/demultiplexer.

•

Compliant with SAS Internal and

External specification.

•

SATA Gen1i, Gen1x, Gen2i,

Gen2x compliant.

•

In the downstream direction, the

QuadSMX 3G demuxes the

initiator-side receive ports to either

the A or B device-side transmit

ports.

•

In the upstream direction, the

QuadSMX 3G selects either the A

or B device-side receive port to

output on the initiator-side transmit

ports.

•

Passes-thru out-of-band (OOB)

signaling.

•

Internal OOB detectors for

COMSAS, COMRESET/COMINIT

and COMWAKE.

•

Provides port reordering to support

standard SATA/SAS 4 channel

connectors and easier PCB

routing.

GENERAL - ETHERNET AND

FIBRE CHANNEL

•

Four channel bi-directional Gigabit

Ethernet and 10 Gigabit Ethernet

(XAUI) link extender and 2:1 serial

multiplexer/demultiplexer.

•

Four channel bi-directional 1G,2G

and 10G Fibre Channel link

extender and 2:1 serial

multiplexer/demultiplexer

•

Provides transmit redundancy for

Ethernet and Fibre Channel Switch

Applications. In this case,data is

broadcast to both Port A and

Port B.

HIGH-SPEED I/O

•

1.0 Gbit/s to 3.2 Gbit/s operation.

•

Automatic amplitude control for

SATA and SAS applications.

•

Programmable receive

equalization, transmit pre-

emphasis and transmit output

swing.

•

Integrated resistive termination

and receive AC coupling.

•

Analog interfaces support SATA

and SAS hot plug.
