•
provides a flexible SCSI bus expander
•
supports any combination of LVD or SE transceivers
•
creates distinct SCSI bus segments that are isolated from each other
•
uses integrated LVDlink transceivers for direct attachment to either
LVD or SE bus segments
•
operates as a SCSI Bus Expander or a SCSI Bus Converter
– LVD to LVD (Ultra320 SCSI or Ultra160 SCSI)
– SE to SE (up to Ultra SCSI)
– LVD to SE (up to Ultra SCSI)
– SE to LVD (up to Ultra SCSI)
•
handles targets and initiators on either the A Side bus or B Side bus
•
accepts any asynchronous or synchronous transfer speeds up to
Ultra320 SCSI (for LVD to LVD mode only)
•
supports dynamic addition/removal of SCSI bus segments using the
isolation mode
•
does not consume a SCSI ID
•
propagates the RESET/ signal from one side to the other regardless
of the SCSI bus state
•
notifies initiator(s) of changes in transmission mode (SE/LVD) on A
or B Side segments by using the SCSI bus RESET/
•
provides a SCSI Busy LED driver for an activity indicator
•
supports cascading of up to four LSI53C320s
•
does not require software
•
requires a 40 MHz Input Clock
•
has a 272-pin Plastic Ball Grid Array package (PBGA).
