3.4.3 Clock Circuitry

Besides the embedded RC oscillators of SAM4CMS16C, three crystal oscillators are assembled on the PL360MB board to obtain a more precise and stable system clock reference:

  • A 24 MHz clock signal generated for the PLC transceiver PL360
  • A 12 MHz clock signal generated for the SAM4CMS16C
  • A low power 32.768 kHz crystal oscillator for the SAM4CMS16C
