IDTCV149 Overview
IDTCV149 is a 56 pin clock device for AMD advance K8 processors. The CPU output buffer is designed to support up to 400MHz processor. This device also implements Band-gap referenced IREF to reduce the impact of VDD variation on differential outputs, which can provide more robust system performance.
