DESCRIPTION  
KEY FEATURES  
The LX5111/5112 SCSI terminators are part of  
cable lengths and impedances. Frequently, this  
situationisnotcontrolledbytheperipheralorhost  
ULTRA-FAST RESPONSE FOR FAST-20  
SCSI APPLICATIONS  
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  
activetechniques. Linfinity'sUltraMAXarchitecture  
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). TheUltraMAXarchitecturealsoeliminates  
theoutputcompensationcapacitortypicalinearlier  
terminator designs. Each is approved for use with  
SCSI-1, -2, -3, UltraSCSI and beyond — providing  
the highest performance alternative available to-  
day.  
designer and, when problems occur, they are the  
first to be made aware of the problem. The  
LX5111/5112 architecture is much more tolerant  
of marginal system integrations.  
35MHz CHANNEL BANDWIDTH  
3.3V OPERATION  
LESS THAN 3pF OUTPUT CAPACITANCE  
Recognizing the needs of portable and  
configurable peripherals, the LX5111/5112 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 LX5111/5112's architecture. Traditional ter-  
minationtechniquesrequirelargestabilizationand  
transient protection capacitors of up to 20µF in  
value and size. The LX5111/5112 architecture  
does not require these components, allowing all  
the cost savings associated with inventory, board  
space, assembly, reliability, and component costs.

Another key improvement offered by the  
LX5111/5112 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
