It is important to have filtering on the supply pins that covers a broad frequency range. Each 1.15 V PLL supply pin should have individual high frequency filtering in the form of a ferrite bead and a 0.1 µF ceramic capacitor. These components should be located very close to the individual PLL supply balls. The impedance of the ferrite bead should far exceed that of the capacitor at frequencies above 10 MHz. The 1.15 V to the PLL supply pins should also have low frequency filtering in the form of an RC filter. This filter can be common to all the PLLs. The voltage drop across the resistor is limited by the 1.15 V regulator tolerance and the DLPC900 voltage tolerance. A resistance of 0.36 Ω and a 100 µF ceramic are recommended. Figure 37 shows the recommended filter topology. Figure 37. Recommended Filter Topology for PLL 1.15-V Supplies |
