QuadSMX 3G
Preview
4-Channel Multiplexer and Link Extender for SAS, SATA, Ethernet and FC
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)
•
Provides transmit redundancy for
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
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.
