... The CLK1, nCLK1 pair can accept most standard differ- ential input levels. With output frequencies up to 180MHz, the ICS87951I is targeted for high performance clock applications. Along with a fully integrated PLL, the ICS87951I contains fre- quency configurable outputs and an external feedback input for regenerating clocks with “zero delay”. ...

... UPPLY ILTERING ECHNIQUES As in any high speed analog circuitry, the power supply pins are vulnerable to random noise. The ICS87951I provides separate power supplies to isolate any high switching noise from the outputs to the internal PLL. V should be individually connected to the power supply plane through vias, and bypass capacitors should be used for each pin ...
