Non-Linear
Single-Ended SCSI Terminators
Lower System Cost
The performance limitations and high system cost
imposed by first generation, linear regulator based SCSI terminators
are overcome with the IMP non-linear terminator architecture.
Linear terminators require two external regulator capacitors
for stability and high-frequency transient response. IMP uses
a non-linear, 35MHz output structure that eliminates the stabilization
and transient response capacitors, saving space and reducing
cost. High bandwidth ensures signal integrity and robust Fast-20
designs.

SCSI Terminators
The non-linear terminator is modeled as a Norton
equivalent circuit of 60 ohms with bus current supplied from
adaptive non-linear circuitry. By maximizing the continuous
24mA line current, the result is a near ideal terminator. Compared
with linear regulator/resistor terminators, the new IMP non-linear
terminators supply higher current at any voltage below 2.5V.
Pin-for-pin replacements offering wider bandwidth and requiring
no external regulator output capacitors are available for the
popular Dallas DS21S07A and for many Unitrode devices. SCSI
peripherals in current production can benefit immediately. Reduced
component count, maximum 24mA current capability, 35MHz bandwidth
and "Real World" cable matching capability add up
to a low cost, reliable terminator solution for new and old
UltraSCSI designs.
