PI2DBS212 2.0GHz, Differential Broadband Signal Switch, 2-Differential Channel, 2:1 Mux/DeMux Switch Features Description * * * * * * * * * Pericom Semiconductor's PI2DBS212 is an 1:2 differential channel multiplexer/demultiplexer switch. Using a specialized design scheme, Pericom has been able to achieve a performance of 3Gbps data rate mux/de-mux function. Due to its bi-directional nature, the PI2DBS212 can be used to allocate bandwidth to two different locations as a demux, or connect two high-speed sources to a single receiver as a mux.
