AC TERMINATION NETWORK — ACT-A
Product Description
The ACT-A is an integrated AC termination network designed to reduce unwanted transmission line
effects on high- speed signal lines.
AC termination provides an alternative termination strategy over series or parallel termination where
power consideration is a concern since DC current is blocked by the capacitor. The ACT-A offers
superior high frequency performance with minimal lead inductance and parasitic capacitance.
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.
