Description
PericomSemiconductors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-
