PI2DBS412 1.8V, 1.8GHz, Differential Broadband Signal Switch, 4-Differential Channel, 2:1 Mux/DeMux Switch, w/ Single Enable Features Description 3dB BW of 1.8 GHz Pericom Semiconductors PI2DBS412 is an 8-to-4 differential channel multiplexer/demultiplexer switch. Using a specialized 4 Differential Channel, 2:1 Mux/DeMux design scheme, Pericom has been able to achieve a performance Low Bit-to-Bit Skew of 3Gbps data rate mux/de-mux function. Due to its bi-directional Low Crosstalk: 68dB 10 MHz nature, the PI2DBS412 can be used to allocate bandwidth to two Low Off Isolation: 77dB 10 MHz different locations as a demux, or connect two high-speed sources V Operating Range: +1.5V to +2.0V CC to a single reciever as a mux. ESD Tolerance: 8kV HBM I/O, 2kV HBM select pin The PI2DBS412 will target the following standards: SAS, SATA I, Packaging (Pb-free & Green): SATA II, INFINIBAND, HYPERTRANSPORT, and RAP ID I/O. 42-contact, TQFN (ZH42) We recommend customers to use Pericom s Re-Driver devices in Applications conjunction with the PI2DBS412 in applications requiring long Routers trace lengths to ensure signal integrity.
