HIGH PERFORMANCE GTL/ECL
TERMINATION NETWORK—RA2
Product Description
The RA-2 is a high performance bus termination network ideal for high speed bus termination
applications. The RA-2 meets all intel
requirements of other high-speed microprocessors such as the DEC Alpha, Motorola PowerPC, SGI
MIPS, and Sun SPARC. A 300-line termination solution can be achieved with just 14 RA-2 networks.
A terminating resistor is used to eliminate unwanted transmission line effects such as ringing,
overshoots and undershoots on printed circuit board traces, and/or provide DC pull-up/pull-down.
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.
