DESCRIPTION

The LX5115 SCSI terminator is part of Linfinity's

UltraMAX family of high-performance, adaptive,

non-linear mode SCSI products, which are de-

signed to deliver true UltraSCSI performance in

SCSI applications. The low voltage BiCMOS ar-

chitecture 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 to-

day.

Another key improvement offered by the

LX5115 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 LX5115

architecture is much more tolerant of marginal

system integrations.

Recognizing the needs of portable and

configurable peripherals, the LX5115 has a TTL

compatible sleep/disable mode. Quiescent

current is typically 150µA 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 LX5115 architecture. Traditional termination

techniques require large stabilization and transient

protection capacitors of up to 20µF in value and

size. The LX5115 architecture does not require

these components, allowing all the cost savings

associated with inventory, board space, assembly,

reliability, and component costs.
