The LX5219 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 applica-

tions. The low voltage BiCMOS architecture em-

ployed 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. It is approved for use with SCSI-

1, -2, -3, UltraSCSI and beyond — providing the

highest performance alternative available today.

lies in its ability to insure reliable, error free com-

munications 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 con-

trolled by the peripheral or host designer and, when

problems occur, they are the first to be made aware

of the problem. The LX5219 architecture is much

more tolerant of marginal system integrations.

configurable peripherals, the LX5219 has an active

low 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

configurability, reducing inventory and product-line

diversity costs. Field configurability can also be

accomplished without physically removing compo-

nents which, often times results in field returns due

to mishandling.

techniques require large stabilization and transient

protection capacitors of up to 20µF in value and

size. The LX5219 architecture does not require these

components, allowing all the cost savings associated

with inventory, board space, assembly, reliability,

and component costs.
