DESCRIPTION
The LX5111/5112 SCSI terminators are part of
Linfinity's UltraMAX family of high-performance,
adaptive, non-linear mode SCSI products, which
are designed to deliver true UltraSCSI performance
in SCSI applications. The low voltage BiCMOS
architecture employed in their design offers su-
perior performance to older linear passive and
active techniques. Linfinity's UltraMAX architecture
employs high-speed adaptive elements for each
channel, thereby providing the fastest response
possible — typically 35MHz, which is 100 times
faster than the older linear regulator/terminator
approach used by other manufacturers. Products
using this older linear regulator approach have
bandwidths which are dominated by the output
capacitor and which are limited to 500KHz (see
further discussion in the Functional Description
section). The UltraMAX architecture also eliminates
the output compensation capacitor typical in earlier
terminator designs. Each is approved for use with
SCSI-1, -2, -3, UltraSCSI and beyond — providing
the highest performance alternative available to-
day.
Another key improvement offered by the
LX5111/5112 lies in their ability to insure reliable,
error-free communications even in systems which
do not adhere to recommended SCSI hardware
design guidelines, such as the use of improper
cable lengths and impedances. Frequently, this
situation is not controlled by the peripheral or host
designer and, when problems occur, they are the
first to be made aware of the problem. The
LX5111/5112 architecture is much more tolerant
of marginal system integrations.
Recognizing the needs of portable and
configurable peripherals, the LX5111/5112 have
a TTL compatible sleep/disable mode. Quiescent
current is typically less than 275µA in this mode,
while the output capacitance is also less than 3pF.
The obvious advantage of extended battery life
for portable systems is inherent in the product's
sleep-mode feature. Additionally, the disable
function permits factory-floor or production-line
configurability, reducing inventory and product-
line diversity costs. Field configurability can also
be accomplished without physically removing
components which, often times results in field
returns due to mishandling.
Reduced component counts is also inherent in
the LX5111/5112's architecture. Traditional ter-
mination techniques require large stabilization and
transient protection capacitors of up to 20µF in
value and size. The LX5111/5112 architecture
does not require these components, allowing all
the cost savings associated with inventory, board
space, assembly, reliability, and component costs.
