the entire frequency range  
DESCRIPTION  
TheIDT88P8341isaSPI(SystemPacketInterface)ExchangewithaSPI-  
3interfaceandaSPI-4interface. Thedatathatenteronthelowspeedinterface  
(SPI-3)aremappedtologicalidentifiers(LIDs)andenqueuedfortransmission  
overthe highspeedinterface (SPI-4). The data thatenteronthe highspeed  
interface (SPI-4) are mapped to logical identifiers (LIDs) and enqueued for  
transmissionoverthelowspeedinterface(SPI-3).AdataflowbetweenSPI-  
3 and SPI-4 interfaces is accomplished with LID maps. The logical port  
addresses and number of entries in the LID maps may be dynamically  
configured.Variousparametersofadataflowmaybeconfiguredbytheuser  
such as buffer memory size and watermarks. In a typical application, the  
IDT88P8341 enables connection of a SPI-3 device to a SPI-4 network
