LVD SCSI Terminator Technical Data Sheet RoHS Compliant Parts Available Description Features This LVD SCSI termination network is designed for high performance active termination of SCSI networks compliant to SPI-2 (Ultra2), SPI-3 (Ultra3) and beyond. Designed with a ceramic substrate and a ball grid array interconnect, this device virtually eliminates channel capacitance and lead inductance, the primary cause of reduced system performance. • • • • • • • 9 Line LVD Termination Network Ultra2 and Ultra3 Compliant Low Channel Capacitance Less than 0.25pF BGA package reliability ±1% Resistor Tolerance Low Channel Cross Talk RoHS Compliant Designs Available • Compatible with both lead and lead-free manufacturing processes BGA packaging has been proven to reduce rework and improve reliability.
