dsPIC33/PIC24 Family Reference Manual

1.0 INTRODUCTION

The dsPIC33/PIC24 family oscillator system includes these characteristics:

• External and internal oscillator sources

• On-chip Phase-Locked Loop (PLL) to boost internal operating frequency on select internal

and external oscillator sources

• Auxiliary PLL (APLL) clock generator to boost operating frequency for ADC and PWM

• Auxiliary Oscillator (AOSC) and Auxiliary PLL Clock (ACLK) generator for USB

• Doze mode for system power savings

• Scalable Reference Clock Output (REFCLKO)

• On-the-fly clock switching between various clock sources

• Linear Feedback Shift Register (LFSR) to generate pseudorandom data

• Fail-Safe Clock Monitoring (FSCM) that detects clock failure and permits safe application

recovery or shutdown

A block diagram of the dsPIC33/PIC24 family oscillator system is shown in Figure 1-1.

Note: This family reference manual section is meant to serve as a complement to device

data sheets. This document applies to all dsPIC33/PIC24 family devices. However,

some features in this document will not apply to all devices.

Please consult the note at the beginning of the “Oscillator Configuration” chapter

in the current device data sheet to check whether this document supports the

device you are using.

Note 1: See Figure 7-1 for the source of the FVCO signal.

2: If the oscillator is used with XT or HS modes, an external parallel resistor with the value of 1 MΩ must be connected.

3: The term, FP, refers to the clock source for all the peripherals, while FCY (or MIPS) refers to the clock source for the CPU.

Throughout this document, FCY and FP are used interchangeably, except in the case of Doze mode. FP and FCY will be different when

Doze mode is used in any ratio other than 1:1.
