scsi termination resistor network low voltage differential (lvd) bb1020dt series 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 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, resulting in the absolute minimum stray capacitance and inductance. www.bitechnologies.com www.irctt.com www.welwyn-tt.com 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 04.12 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 resistance nominal (r1 & r2) 475?, 121? absolute tolerance 1% temperature coeffcient of resistance 100 ppm/c interlead capacitance, maximum 0.1 pf operating temperature range -55c to +125c power rating (per network @ 70c) 1 watt description schematics electrical 1 r1 = 47 5 (18 places) r2 = 12 1 (9 places) 1 specifcation subject to change without notice.
