10.1.4 Circuit Board Layout
Board layout and capacitor choice affect each other and determine the performance of the PLL. Figure
30 illustrates a suggested layout for the PLL filter components and for bypassing the analog supply volt-
age. The 10 µF bypass capacitor is an electrolytic in a surface-mount case A or thru-hole package. RFILT,
CFILT, CRIP, and the 0.1 µF decoupling capacitor are in an 0805 form factor. The 0.01 µF decoupling
capacitor is in the 0603 form factor. The traces are on the top surface of the board with the IC so that there
is no via inductance. The traces themselves are short to minimize the inductance in the filter path. The
VARX and AGND traces extend back to their origin and are shown only in truncated form in the drawing.
