Abstract
A ferrite bead is placed in series with a terminating resistor on a transmission line such as a clock transmission line. In lower frequency ranges where the ferrite bead is substantially not effective, the transmission line will be effectively terminated by the resistor. In higher frequency ranges where the resistor is substantially no longer effective, the transmission line will be terminated by the ferrite bead. In one aspect, the resistor and ferrite bead are provided in a single surface mount package.
