PI3DBS12412A
3.3V, 10-12Gbps 2-Lane 2:1 Mux/De-Mux Switch
Pericom Semiconductors PI3DBS12412A is an 8 to 4
Features
differential channel multiplexer/demultiplexer switch.
This solution can switch multiple signal types up to data rate
4 Differential Channel, 2:1 Mux/DeMux
of 12Gbps. Using a unique design technique, Pericom has
Up to 12Gbps data rate for SAS 3.0 Application
been able to minimize the impedance of the switch such
Compatible with Thunderbolt signaling,
that the attenuation observed through the switch is minimal.
10.3125Gbps
The unique design technique also offers a layout targeted for
Thunderbolt & SAS 3.0 signals, which minimizes the channel
10Gbps Ethernet, USB 3.1
to channel skew as well as channel to channel crosstalk as
Bi-directional operation
required by high speed signals.
