LVDS Test Circuit

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 PI6LC48L0201 provides separate power supplies to isolate any high switching noise

from the outputs to the internal PLL. VDD, VDDA and VDDO 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.
