MODEL BB1020DT
SCSI Termination Resistor network
Low Voltage Differential (LVD)
DISCRIPTION
Model BB1020DT is a SCSI LVD termination network designed to terminate high performance SPI-2 (Ultra2)
and SPI-3 (Ultra3) bused 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.
