LX5115A
ULTRA 9-CHANNEL SCSI TERMINATOR
PRODUCTION DATA SHEET
DESCRIPTION
The LX5115A SCSI terminator is 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 its design offers superior 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 today.
Another key improvement offered by the
LX5115A 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
LX5115A architecture is much more tolerant of
marginal system integrations. Recognizing the
needs of portable and configurable peripherals, the
LX5115A has a TTL compatible sleep/disable
mode. Quiescent current is typically 200µA 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
LX5115A architecture. Traditional termination
techniques require large stabilization and transient
protection capacitors of up to 20µF in value and
size. The LX5115A architecture does not require
these components, allowing all the cost savings
associated with inventory, board space, assembly,
reliability, and component costs.
