About this manual

This reference manual describes the operation of the oscillator system in dsPIC30F SMPS devices. Key features include external and internal oscillators, an on-chip Phase Lock Loop (PLL) for frequency multiplication, dynamic clock switching between sources, and a Fail-Safe Clock Monitor (FSCM). The system supports industrial-grade and extended-temperature range operation. This manual is written in Chinese.

Frequently asked questions

What are the oscillator source options for the dsPIC30F?

The system clock source can be provided by the Master Oscillator, Internal Fast RC Oscillator, Master Oscillator with PLL, or Internal Fast RC Oscillator with PLL.

What is the function of the Fail-Safe Clock Monitor (FSCM)?

The FSCM detects clock faults and allows for a safe recovery or shutdown of the application.
