DESCRIPTION:
requirements, for Intel advance P4 processors. The CPU output buffer is
designed to support up to 400MHz processor. One dedicated PLL for Serial
ATA clock provides high accuracy frequency. This device also implements
Band-gap referenced I
outputs, which can provide more robust system performance.
which allows for isolated changes instead of affecting other clock groups.
IDTCV115-2 is a 56 pin clock device, complying the latest Intel CK410
