SCSI Bus Support (Continued)
Supports SCSI SCRIPTS load
and store instructions for more
efficient moving of data between
memory and chip register space
Includes 4 KB internal RAM for
SCRIPTS instruction storage to
reduce or eliminate instruction
fetches over the PCI bus
Improved support for large block
transfers at Ultra2 SCSI speeds
Termination:
–
Active, automatic
–
LVDlink provides automatic
switching between single-
ended and LVD signaling
–
Automatically enters high-
impedance state when
connected to a HVD signal
Provides data reliability and
cable distance of differential
SCSI without the cost of
external differential transceivers
Improves connectivity (up to 15
LVD Ultra2 SCSI devices) and
cable lengths (up to 12.5 meters
of Ultra SCSI - longer cables
may be possible in point-to-
point connections)
Uses same internal cables as
Ultra SCSI and same connectors
as Fast/Ultra SCSI
Supports SCAM (SCSI Configured
AutoMatically) Level 1 functionality
Uses LSI53C895 proprietary
Ultra2 SCSI I/O RISC processor
With appropriate cables, supports
8-bit hard drives, CD ROMs, tape
backups, hard disks, scanners
and other 8-bit SCSI devices in
Fast/Ultra SE mode only

interoperability are rigorously tested and our ISO-9001 certified fabrication
facilities assures users of the highest levels of product quality and reliability.

Balancing backward compatibility with I/O performance and lower costs,
the LSI53C895 integrates our universal LVDlink transceivers with the Ultra2
SCSI I/O processor. Depending on SCSI bus connections, bus cabling conditions
are sensed and the universal LVDlink transceivers automatically select single-
ended or LVD SCSI modes and indicate the mode with the on-board SE or
LVD LEDs. In single-ended mode, the LSI8951U performs synchronous data
transfers up to Ultra SCSI rates, subject to standard Ultra SCSI cable distance
and connected device constraints. In LVD mode, the host adapter supports up
to 12.5-meter cables and up to 15 LVD devices with the same cables and
connectors as defined in the SCSI-3 Parallel Interface ANSI standard.
LVDlink transceivers also provide fail-safe operation of the receiver by
detecting when the LSI8951U is connected to a high voltage differential
(HVD) signal. When connected to HVD, the LSI8951U
’
s SCSI bus enters a
high-impedance mode and activates the on-board HVD LED.
