Oscillator Recommendations
Remark:
Values of capacitors C1’, C2’ and R’ depend on used crystal or resonator and must be
specified in cooperation with the manufacturer.
Cautions: 1. External clock input is prohibited.
2. Wire as follows in the area enclosed by the broken lines in the above figure to
avoid an adverse effect from wiring capacitance.
•
Keep the wiring length as short as possible.
•
Do not cross the wiring with the other signal lines.
•
Do not route the wiring near a signal line through which a high fluctuating
current flows.
•
Always make the ground point of the oscillator capacitor the same potential
as CV
SS
.
•
Do not ground the capacitor to a ground pattern through which a high
current flows.
•
Do not fetch signals from the oscillator.
