DESCRIPTION

The LX5111A/5112A 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

LX5111A/12A 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

LX5111A/12A architecture is much more tolerant

of marginal system integrations.

Recognizing the needs of portable and

configurable peripherals, the LX5111A/12A 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 LX5111A/12A's architecture. Traditional ter-

mination techniques require large stabilization and

transient protection capacitors of up to 20µF in

value and size. The LX5111A/12A architecture

does not require these components, allowing all

the cost savings associated with inventory, board

space, assembly, reliability, and component costs.
