3.24.5. Custom Solutions
As long as filter performance as specified in the previous “Filter Specification” figure and other
requirements outlined in Section 3.24.1. are satisfied, other solutions are acceptable. Custom solutions
should be simulated against a standard reference core model, which is shown in the figure below.

NOTES:
1. 0.1
Ω resistors represent package routing1.
2. 120 pF capacitor represents internal decoupling capacitor.
3. 1 k
Ω resistor represents small signal PLL resistance.
4. Be sure to include all component and routing parasitics.
5. Please sweep across component/parasitic tolerances.
6. To observe IR drop, use DC current of 30 mA and minimum VCC

level.
1 For other modules (interposer, DMM, etc), adjust routing resistor if desired, but use minimum numbers.
