IMP5226
18-Line SCSI Terminator
DESCRIPTION
The IMP5226 SCSI terminator is part of
IMP's family of high-performance, adaptive,
non-linear mode SCSI products, which are
designed to deliver true UltraSCSI perfor-
mance in SCSI applications. The low-voltage
BiCMOS architecture employed in its design
offers performance superior to older linear
passive and active techniques. IMP's
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 IMP
architecture also eliminates the output
compensation capacitor required in earlier
terminator designs. Each is approved for use
with SCSI-1, -2, -3, UltraSCSI and beyond
— providing the highest performance
alternative available today.
The IMP5226 architecture is much more
tolerant of marginal system integrations. A
key improvement offered by the IMP5226 lies

in its 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
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 the problem.
To enter the disconnect mode, the
disconnect pin must be driven high, thereby
disconnecting the IMP5226 from the SCSI
bus. Quiescent current is typically less than
200
μ
A in this mode, while the output
capacitance is less than 3pF.
Reduced component count is also inherent
in the IMP5226 architecture. Traditional
termination techniques require large stabiliza-
tion and transient protection capacitors of up
to 20
μ
F in value and size. The IMP5226
architecture does not require these compo-
nents, allowing all the cost savings associated
with inventory, board space, assembly,
reliability, and component costs.
The IMP5226 is a superior pin-for-pin
replacement for the LX5207, the UC5601/
5602/5608/5610/5618 and the Burr Brown
REG5608/5618.
