scsi terminaton resistor network low voltage diferental (lvd) bb1020dt series model bb1020dt is a scsi lvd terminaton network designed to terminate high performance spi-2 (ultra2) and spi-3 (ultra3) bussed applicatons. wide scsi bus applicatons can be terminated with three bb1020dt net - works and a linear regulator ic. for use in high-speed scsi bus applicatons, the bb1020dt utlizes thick flm resistors on a ceramic substrate with ball grid array (bga) terminals. resistors and solder balls reside on the same side of the ceramic substrate, resultng in the absolute minimum stray capacitance and inductance. spi-2 (ultra2) and spi-3 (ultra3) compliant each network contains lvd terminaton for up to 9 lines superior high frequency performance minimal stray capacitance and inductance surface mountable with automatc pick and place equipment resistance nominal (r1 & r2) 475?, 121? absolute tolerance 1% temperature coefcient of resistance 100 ppm/c interlead capacitance, maximum 0.1 pf operatng temperature range -55c to +125c power ratng (per network @ 70c) 1 wat descripton schematcs electrical 1 r1 = 47 5 (18 places) r2 = 12 1 (9 places) 1 specifcaton subject to change without notce. ma ke p ossibl e resistors 07.14 general note tt electronics reserves the right to make changes in product specifcation without notice or liability. all information is subject to tt electronics own data and is considered accurate at time of going to print. ? tt electronics plc www.ttelectronicsresistors.com all pb-free parts comply with eu directve 2011/65/eu (rohs2)
