The LSI22802 is a PCI-dual
channel multi-function, single-ended
Ultra SCSI solution.
OVERVIEW
The LSI22802 host adapter is a multi-function host adapter providing two
independent differential Ultra SCSI channels. Both SCSI channels are identical,
offering increased connectivity without utilizing additional PCI slots. A single
board provides a powerful dual channel, multitasking interface for Ultra SCSI
peripherals such as disk, tape, CD-ROM, and other SCSI devices.
The LSI22802 leverages the LSI53C876 PCI dual channel SCSI multi-
function controller capable of connecting directly to the PCI bus, presenting
one electrical load, while functioning as a single 32-bit PCI DMA bus master.
The LSI22802 includes an on-board configuration utility allowing
viewing and changing of default configuration settings for the host adapter
and connected SCSI peripherals.
The device also provides advanced features for ease-of-use by modifying
the on-board terminators depending on cable configuration and LEDs to
help with termination power (TERMPWR) monitoring.
The LSI22802 has advanced features which make it the right choice for
applications requiring up to 30 connected peripherals, or for isolating
peripheral classes (e.g. CD-ROMs and tape drives on one channel and high
performance disk drives on the other).
