DESCRIPTION:
buffer is designed to support up to 400MHz processor. This device also
implements Band-gap referenced I
differential outputs, which can provide more robust system performance.
for isolated changes instead of affecting other clock groups.
IDTCV136 is a 56 pin clock device for Intel P4 processors. The CPU output
Each CPU/SRC clock has its own Spread Spectrum selection, which allows
