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 SCHEMATIC R1 = 475Ω (18 places) R2 = 121Ω (9 places) ELECTRICAL1 Resistance Nominal (R1 & R2) 475Ω, 121Ω Absolute Tolerance ±1% Temperature Coefficient of Resistance (TCR) ±100 ppm/°C Interlead Capacitance, Maximum 0.1 pF Operating Temperature Range -55°C to +125°C 1 Watt Power Rating (per network @ 70°C) 1 Specifications subject to change without notice.
