PRODUCT HIG HLIG HT
The IMP5219 SCSI terminator is part of IMP's
SCSI terminator 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 its design offers perfor-
mance superior to older linear passive and active
techniques. IMP's SCSI terminator 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). This new architecture also eliminates the
output compensation capacitor required in earlier
terminator designs. Each is approved for use with
SCSI-1, -2, -3, UltraSCSI and beyond — providing
the highest performance alternative available today.
Another key improvement offered by the
IMP5219 lies in its 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 IMP5219 architecture is much more
tolerant of marginal system integrations.
Recognizing the needs of portable and
configurable peripherals, the IMP5219 has an active
high TTL compatible sleep/disable mode. Quiescent
current is typically less than 275
μ
A 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 results in field returns due to
mishandling.
Reduced component count is also inherent in the
IMP5219 architecture. Traditional termination
techniques require large stabilization and transient
protection capacitors of up to 20
μ
F in value and size.
The IMP5219 architecture does not require these
components, allowing all the cost savings associated
with reduced inventory, board space, and assembly, plus
higher reliability.
