Diodes Menu Close


The PI3DBS16215 is a 4-to-2 differential channel multiplexer/demultiplexer switch. This solution can switch multiple signal types up to data rate of 20Gbps. Using a unique design technique, Diodes is able to minimize the impedance of the switch, so the attenuation observed through the switch is minimal. The unique design technique also offers a layout targeted for USB3.0, USB3.1, 10GE, Thunderbolt 3, and SAS3.0 signals, which minimizes the channelto- channel skew as well as channel-to-channel crosstalk as required by high-speed signals.
