PRODUCT BRIEF

PI3DBS12212A

The PI3DBS12212A is an 4 to 2 differential channel multiplexer/

demultiplexer switch. This solution can switch multiple signal types

up to data rate of 12Gbps. Using a unique design technique, Di-

odes has been able to minimize the impedance of the switch such

that the attenuation observed through the switch is minimal. The

unique design technique also offers a layout targeted for USB3.0,

USB3.1, 10GE, Thunderbolt, and SAS3.0 signals, which minimizes

the channel to channel skew as well as channel to channel cross-

talk as required by high speed signals.
