Flexible Oscillator Structure

  • High-Precision Internal Oscillator:
    • Software-selectable frequency range up to 32 MHz
    • ±2% at calibration (nominal)
  • 4x PLL for Use with External Sources:
    • Up to 32 MHz (4-8 MHz input)
  • 2x PLL for Use with the HFINTOSC:
    • Up to 32 MHz
  • Low-Power Internal 31 kHz Oscillator (LFINTOSC)
  • External 32.768 kHz Crystal Oscillator (SOCS)
  • External Oscillator Block with:
    • Three Crystal/Resonator modes up to 20 MHz
    • Three External Clock modes up to 32 MHz
  • Fail-Safe Clock Monitor:
    • Detects clock source failure
  • Oscillator Start-up Timer (OST):
    • Ensures stability of crystal oscillator sources
