The LX5119 UltraMAX
TM
terminator represents
next-generation technology for SCSI termina-
tion applications. The low-voltage BiCMOS
architecture employed in its design offers
superior performance to older passive and
active techniques.
Linfinity's architecture employs high-speed
adaptive elements for each channel, providing
the fastest response possible. The channel
bandwidth is typically 35MHz. The LX5119
compares favorably to older linear regulator
approaches whose bandwidth's are domi-
nated by the output compensation capacitor
and are limited to the 500KHz bandwidth
region (see further discussion in the Func-
tional Description section). Linfinity's archi-
tecture also eliminates the output compen-
sation capacitor typical in earlier terminator
designs. Each is approved for use with SCSI-
1,-2,-3, ULTRA and beyond — providing the
highest performance alternative available to-
day.
Another key improvement of LX5119 prod-
ucts lies in their ability to ensure reliable, error-
free communications even in systems which
do not necessarily adhere to recommended
SCSI hardware design guidelines, such as the
use of improper cable lengths and imped-
ances. 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 these problems. The
LX5119 architecture is much more tolerant
of marginal system integrations.
Recognizing the needs of portable and
configurable peripherals, the LX5119 has a
TTL compatible sleep/disable mode. To
enter this mode, the DIS pin must be driven
low, thereby disconnecting the LX5119 from
the SCSI bus. Quiescent current is less than
150μA in this mode.
Reduced component count is also inherent
in the LX5119 architecture. Traditional ter-
mination techniques require large stabiliza-
tion and transient protection capacitors of up
to 20μF in value and size. The LX5119
architecture does not require these compo-
nents, allowing all the cost savings associated
with inventory, board space, assembly, re-
liability, and component costs.
