Abstract
The present invention discloses a novel method and apparatus for making a jitter transfer function of a phase-locked loop independent from the data transition density. The present invention is further discloses a phase-locked loop which has a loop bandwidth and a loop gain in the passband which are both independent from the received data patterns. By making the loop bandwidth independent of the received data pattern, the noise filtering performance of the phase-locked loop may be optimized.
