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.
