Description

The LX5225 SCSI terminator is part of Linfinity's UltraMAX family of high-performance, adaptive non-linear mode SCSI products, which are designed to deliver true UltraSCSI performance in SCSI applications. The low voltage BiCMOS architecture employed in its design offers superior performance to older linear passive and active techniques.

Linfinity's UltraMAX 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 LX5225 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 UltraMAX architecture also eliminates the output compensation capacitor typical in earlier terminator designs. Each is approved for use with SCSI- 1, -2, -3, UltraSCSI and beyond - providing the highest performance alternative available today.
