It features output phase programmability which is necessary to optimize the timing of high-performance computer and communication systems. The user can program both the frequency and the phase of the output banks through nF[0:1] and DS[0:1] pins. The adjustable phase feature allows the user to skew the outputs to lead or lag the reference clock. Any one of the outputs can be connected to feedback input to achieve different reference frequency multiplication and divide ratios and zero input-output delay. The device also features split output bank power supplies which enable the user...
