QuadSMX 3G
Preview
4-Channel Multiplexer and Link Extender for SAS, SATA, Ethernet and FC
FEATURES
GENERAL - SATA AND SAS
鈥?/div>
Four bi-directional 2:1 SATA or
SAS multiplexer/demultiplexer.
鈥?/div>
Compliant with SAS Internal and
External specification.
鈥?/div>
SATA Gen1i, Gen1x, Gen2i,
Gen2x compliant.
鈥?/div>
In the downstream direction, the
QuadSMX 3G demuxes the
initiator-side receive ports to either
the A or B device-side transmit
ports.
鈥?/div>
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.
鈥?/div>
Passes-thru out-of-band (OOB)
鈥?/div>
Provides transmit redundancy for
signaling.
鈥?/div>
Internal OOB detectors for
COMSAS, COMRESET/COMINIT
and COMWAKE.
鈥?/div>
Provides port reordering to support
standard SATA/SAS 4 channel
connectors and easier PCB
routing.
GENERAL - ETHERNET AND
FIBRE CHANNEL
鈥?/div>
Four channel bi-directional Gigabit
Ethernet and 10 Gigabit Ethernet
(XAUI) link extender and 2:1 serial
multiplexer/demultiplexer.
鈥?/div>
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
鈥?/div>
1.0 Gbit/s to 3.2 Gbit/s operation.
鈥?/div>
Automatic amplitude control for
SATA and SAS applications.
鈥?/div>
Programmable receive
equalization, transmit pre-
emphasis and transmit output
swing.
鈥?/div>
Integrated resistive termination
and receive AC coupling.
鈥?/div>
Analog interfaces support SATA
and SAS hot plug.
