The LX5122 Plug and Play UltraMAX
TM
ter-
minator represents next-generation technol-
ogy for SCSI termination 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
LX5122 compares favorably to older linear
regulator approaches whose bandwidth's
are dominated by the output compensation
capacitor and are limited to the 500KHz
bandwidth region (see further discussion in
the Functional Description section).
Linfinity's architecture also eliminates the
output compensation capacitor typical in
earlier terminator designs. Each is approved
for use with SCSI-1, -2, -3, ULTRA and
beyond — providing the highest perfor-
mance alternative available today.
Another key improvement of LX5122
products lies in their ability to insure re-
liable, error free communications even in
systems which do not necessarily adhere to
recommended SCSI hardware design guide-
lines, 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 these
problems. The LX5122 architecture is much
more tolerant of marginal system integra-
tions.
Recognizing the needs of portable and
configurable peripherals, the LX5122 has a
TTL compatible sleep/disable mode. Qui-
escent current is less than 150μA in this
mode.
Reduced component count is also inher-
ent in the LX5122 architecture. Traditional
termination techniques require large stabi-
lization and transient protection capacitors
of up to 20μF in value and size. The LX5122
architecture does not require these com-
ponents, allowing all the cost savings as-
sociated with inventory, board space, as-
sembly, reliability, and component costs.
The LX5122 has multiple disables for full
Plug and Play SCSI capability for Host Bus
Adapters with 3 SCSI connectors. It also
splits the upper 9 termination lines for
mixing 16-bit (wide) and 8-bit (narrow)
buses with minimal board trace
capacitance.
