Clock Options and Oscillators
There are 7 clock options provided by the dsPIC33F:
FRC Oscillator
FRC Oscillator with PLL
Primary (XT, HS or EC) Oscillator
Primary Oscillator with PLL
Secondary (LP) Oscillator
LPRC Oscillator
The FRC (Fast RC) internal oscillator runs at a nominal
frequency of 7.37 MHz. The user software can tune the
FRC frequency. User software can specify a factor by
which this clock frequency is scaled.
The primary oscillator can use one of the following as
its clock source:
1.
XT (Crystal): Crystals and ceramic resonators in
the range of 3 MHz to 10 MHz. The crystal is
connected to the OSC1 and OSC2 pins.
2.
HS (High-Speed Crystal): Crystals in the range
of 10 MHz to 40 MHz. The crystal is connected
to the OSC1 and OSC2 pins.
3.
EC (External Clock): External clock signal in the
range of 0.8 MHz to 64 MHz. The external clock
signal is directly applied to the OSC1 pin.
The secondary (LP) oscillator is designed for low power
and uses a 32 kHz crystal or ceramic resonator. The LP
oscillator uses the SOSCI and SOSCO pins.
The LPRC (Low-Power RC) internal oscIllator runs at a
nominal frequency of 32.768 kHz. Another scaled
reference clock is used by the Watchdog Timer (WDT)
and Fail-Safe Clock Monitor (FSCM).
The clock signals generated by the FRC and primary
oscillators can be optionally applied to an on-chip
Phase Locked Loop (PLL) to provide a wide range of
output frequencies for device operation. The input to
the PLL can be in the range of 1.6 MHz to 16 MHz, and
the PLL Phase Detector Input Divider, PLL Multiplier
Ratio and PLL Voltage Controlled Oscillator (VCO) can
be individually configured by user software to generate
output frequencies in the range of 25 MHz to 160 MHz.
The output of the oscillator (or the output of the PLL if
a PLL mode has been selected) is divided by 4 to
generate the device instruction clock (FCY). FCY
defines the operating speed of the device, and speeds
up to 40 MHz are supported by the dsPIC33F
architecture.
The dsPIC33F oscillator system provides:
Various external and internal oscillator options as
clock sources
An on-chip PLL to scale the internal operating
frequency to the required system clock frequency
The internal FRC oscillator can also be used with
the PLL, thereby allowing full-speed operation
without any external clock generation hardware
Clock switching between various clock sources
Programmable clock postscaler for system power
savings
A Fail-Safe Clock Monitor (FSCM) that detects
clock failure and takes fail-safe measures
A Clock Control register (OSCCON)
Nonvolatile configuration bits for main oscillator
selection.
A simplified block diagram of the oscillator system is
shown in Figure 6-1.
