I M P 5 2 2 51 DATA COMMUNICATIONS 18-Line Plug and Play SCSI Terminator The IMP5225 SCSI terminator is part of IMP's family of highperformance SCSI terminators, which are designed to deliver true UltraSCSI performance. The BiCMOS design offers superior performance over first generation linear passive and active techniques. IMP's new 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. Products using the older regulator/resistor architecture have bandwidths which are dominated by the reference stabilization output capacitor and are therefore limited to 500kHz (see further discussion in the Functional Description section).
