Description
Model BB1020DT is a SCSI LVD termination network designed to terminate high performance SPI-2
(Ultra2) and SPI-3 (Ultra3) bussed applications. Wide SCSI bus applications can be terminated with three
BB1020DT networks and a linear regulator IC.
For use in high-speed SCSI bus applications, the BB1020DT utilizes thick film resistors on a ceramic
substrate with ball grid array (BGA) terminals. Resistors and solder balls reside on the same side of the
ceramic substrate, resulting in the absolute minimum stray capacitance and inductance.
