Bi BB1020DTLF7 Scsi termination resistor network low voltage differential (lvd) Datasheet

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.
FEATURES
•
SPI-2 (Ultra2) and SPI-3 (Ultra3) compliant
•
Each network contains LVD termination for up to 9 lines
•
Superior high frequency performance
•
Minimal stray capacitance and inductance
•
Surface mountable with automatic pick and place equipment
