The PIC32MX1XX/2XX oscillator system has the
following modules and features:
• A Total of four external and internal oscillator 

options as clock sources

• On-Chip PLL with user-selectable input divider, 

multiplier and output divider to boost operating 
frequency on select internal and external 
oscillator sources

• On-Chip user-selectable divisor postscaler on 

select oscillator sources

• Software-controllable switching between 

various clock sources

• A Fail-Safe Clock Monitor (FSCM) that detects 

clock failure and permits safe application recovery 
or shutdown

• Dedicated On-Chip PLL for USB peripheral
A block diagram of the oscillator system is provided in
