Oscillator / Resonator Start-up
As the device voltage increases from V
required for the oscillator to start oscillating depends on many factors. These include:
• Crystal / resonator frequency
• Capacitor values used (C1 and C2 in
• Device V
• System temperature
• Series resistor value (and type) if used (Rs in
• Oscillator mode selection of device (which selects the gain of the internal oscillator inverter)
• Crystal quality
• Oscillator circuit layout
• System noise
