PRODUCT HIG HLIG HT
The IMP5121 Plug and Play terminator
represents next-generation technology for SCSI
termination applications. The low-voltage
BiCMOS architecture employed in its design
offers performance superior to older passive
and active techniques. IMP's architecture
employs high-speed adaptive elements for each
channel, providing the fastest response
possible. The channel bandwidth is typically
35MHz. The IMP5121 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). IMP's architecture also eliminates
the output compensation capacitor required in
earlier terminator designs. Each is approved
for use with SCSI-1, -2, -3, ULTRA and
beyond — providing the highest performance
alternative available today.
Another key improvement of the IMP5121
products lies in their ability to insure reliable,
error free communications even in systems
which do not necessarily adhere to recom-
mended 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
to be made aware of these problems. The
IMP5121 architecture is much more tolerant
of marginal system integrations.
Recognizing the needs of portable and
configurable peripherals, the IMP5121 has a
TTL compatible sleep/disable mode.
Quiescent current is typically less than 375
μ
A
in this mode, while the output capacitance is
less than 3pF.
Reduced component count is also inherent
in the IMP5121 architecture. Traditional
termination techniques require large stabiliza-
tion and transient protection capacitors of up
to 20
μ
F in value and size. The IMP5121
architecture does not require these compo-
nents, allowing all the cost savings associated
with inventory, board space, assembly,
reliability, and component costs.
The IMP5121 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.
