Description

PericomSemiconductor’sPI2DBS6212isa4to2bi-directional

differentialchannelmultiplexer/demultiplexerswitchsupport-

ing6.5Gbpsapplications.Duetoitslowbit-to-bitskew,high

channel-to-channelnoiseisolationandhighbandwidth,this

productisidealforswitchingtwosourcestoasinglereceiver,or

alternatively,onesourcetotworeceivers.

Application

-SAS2,SATA3,XAUI,Inniband,HypeTransport,RapidI/O

-Computers,servers,storage,instrumentation,telecom,network-
