Eliminating Capacitor Anti-Resonance Issue
A common design practice is to parallel decade capacitance values to extend
the high frequency performance of the filter network. This causes an unintende
and often over-looked effect of anti-resonant peaks in the filter networks
combined impedance. X2Y’s very low mounted inductance allows designers
to use a single, higher value part and completely avoid the anti-resonance
problem. The impedance graph on right shows the combined mounted
impedance of a 1nF, 10nF & 100nF 0402 MLC in parrallel in RED. The MLC
networks anti-resonance peaks are nearly 10 times the desired impedance. A
100nF and 47nF X2Y are plotted in BLUE and GREEN. (The total capacitance of
X2Y (Circuit 2) is twice the value, or 200nF and 98nF in this example.) The sigle
X2Y is clearly superior to the three paralleled MLCs.
X2Y High Performance Power Bypass - Improve Performance, Reduce Space & Vias
Actual measured performance of two high performance SerDes FPGA designs demonstrate how a 13 component X2Y bypass network significantly out
performs a 38 component MLC network. For more information see http://johansondielectrics.com/pdfs/JDI_X2Y_STXII.pdf
