(2)
Insert a laminated ceramic capacitor as a bypass capacitor for each V
capacitors to the power supply pins, and use components with a frequency characteristic suitable
for the operating frequency of the LSI, as well as a suitable capacitance value.
(3)
Keep the wiring from the PLL V
make the pattern width large, to minimize the inductance component.
Connect the EXTAL pin to V
The analog power supply system of the PLL is sensitive to a noise. Therefore the system
malfunction may occur by the intervention with other power supply. Do not supply the analog
power supply with the same resource as the digital power supply of V
Note: The values for CL1, CL2, and the damping resistance should be determined after
