DUAL THEVENIN TERMINATION NETWORK—RN3
Product Description
The RN-3 is an integrated dual Therein termination network designed to eliminate transmission line
effects on high-speed data lines. SCSI (Small Computer Systems Interface) is a bus interface
covered by an ANSI Standard that allows for peripheral devices to be connected in a daisy chain and
communicate with the host processor Fast edge signals transmitted through the SCSI cable can
generate ringing on the bus that can slow down communication between the host and peripherals.
The SCSI standard recommends Therein termination at the host and peripheral locations to
eliminate these transmission line effects.
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
afford the benefits of board space savings, reduced assembly costs, and increased reliability with
fewer components.
