PCB Layout Suggestion
Note:
1. This is only a suggested layout. There may be alternate solutions depending on actual PCB design and layout.
2. As a general rule, C1-C7 should be placed as close as possible to their respective VDD.
3. Recommended capacitor values:
100/66 MHz
Clock from
C1-C7 = 0.1μF, ceramic
