POWER SUPPLY FILTERING TECHNIQUES
high speed analog circuitry, power supply pins vulnerable random noise. ICS8761 provides separate power supplies isolate high switching noise from outputs internal PLL. VDD, VDDA, VDDOx should individually connected power supply plane through vias, bypass capacitors should used each pin. achieve optimum jitter performance, power supply isolation required. Figure illustrates resistor along with 10µF .01µF bypass capacitor should connected each VDDA.
