Power Supply Filtering Techniques

As in any high speed analog circuitry, the power supply pins are vulnerable to random noise. To achieve optimum jitter perfor-

mance, power supply isolation is required. The PI6LC48C21 provides separate power supplies to isolate any high switching noise

from the outputs to the internal PLL. VDD and VDDA should be individually connected to the power supply plane through vias, and

0.1μF bypass capacitors should be used for each pin. Figure below illustrates this for a generic VDD pin and also shows that VDDA

requires that an additional 10Ω resistor along with a 10μF bypass capacitor be connected to the VDDA pin.
