| CALIFORNIA MICRO DEVICES PRN103/153/125/155 Thin Film Differential Terminator Resistor Network Features * Thin film on silicon * Tolerance 2% * Wide body surface mount SOIC and DIP configuration * Drop-in replacement to thick film networks * Also available in custom schematic and configuration Applications * Differential SCSI Termination * SCSI Host Adapter Cards and Other SCSI Devices Product Description The PRN103/153/125/155 is a high performance Integrated Passive Device (IPD) designed to eliminate transmission line effects on high-speed data lines on a special bus called SCSI (Small Computer Systems Interface). SCSI is a bus interface covered by an ANSI standard that allows for an input/output bus to connect small computers with a variety of peripheral devices. Proper resistor termination requires a resistor whose value closely matches the characteristic impedance of the transmission line. Thin film networks offer significant advantages over conventional thick film processes in terms of tighter absolute and ratio tolerances, greater stability, lower noise, and Temperature Coefficient of Resistance (TCR). Furthermore, they offer superior high frequency performance with minimal parasitic inductance and capacitance. Integrated thin film networks also offer the benefits of board space savings, reduced assembly costs, and increased reliability with fewer components.
