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-direction-
al 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.
The PI2DBS212 will target the following standards: SAS, SATA
I, SATA II, XAUI, INFINIBAND, HYPERTRANSPORT, and
RAP ID I/O, for application in computers, consumer electronics,
instrumentation, etc.
