8.1
The
dsPIC33FJ16MC304 devices provide seven system
clock options:
• Fast RC (FRC) Oscillator
• FRC Oscillator with PLL
• Primary (XT, HS or EC) Oscillator
• Primary Oscillator with PLL
• Secondary (LP) Oscillator
• Low-Power RC (LPRC) Oscillator
• FRC Oscillator with postscaler
8.1.1
8.1.1.1
The Fast RC (FRC) internal oscillator runs at a nominal
frequency of 7.37 MHz. User software can tune the
FRC frequency. User software can optionally specify a
factor (ranging from 1:2 to 1:256) by which the FRC
clock frequency is divided. This factor is selected using
the FRCDIV<2:0> (CLKDIV<10:8>) bits.
8.1.1.2
The primary oscillator can use one of the following as
its clock source:
• XT (Crystal): Crystals and ceramic resonators in
• HS (High-Speed Crystal): Crystals in the range of
• EC (External Clock): The external clock signal is
8.1.1.3
The secondary (LP) oscillator is designed for low power
and uses a 32.768 kHz crystal or ceramic resonator.
The LP oscillator uses the SOSCI and SOSCO pins.
8.1.1.4
The LPRC (Low-Power RC) internal oscIllator runs at a
nominal frequency of 32.768 kHz. It is also used as a
reference clock by the Watchdog Timer (WDT) and
Fail-Safe Clock Monitor (FSCM).
8.1.1.5
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
configuration is described in Section 8.1.3 “PLL
Configuration”.
The FRC frequency depends on the FRC accuracy
(see Table 24-18) and the value of the FRC Oscillator
Tuning register (see Register 8-4).

The oscillator source used at a device Power-on

settings. The oscillator Configuration bit settings are

8.1.3
The primary oscillator and internal FRC oscillator can
optionally use an on-chip PLL to obtain higher speeds
of operation. The PLL provides significant flexibility in
selecting the device operating speed. A block diagram
of the PLL is shown in Figure 8-2.

The PLL Feedback Divisor, selected using the
PLLDIV<8:0> bits (PLLFBD<8:0>), provides a factor ‘M’,
by which the input to the VCO is multiplied. This factor
must be selected such that the resulting VCO output
frequency is in the range of 100 MHz to 200 MHz.
The VCO output is further divided by a postscale factor
‘N2.’ This factor is selected using the PLLPOST<1:0>
bits (CLKDIV<7:6>). ‘N2’ can be either 2, 4 or 8, and
must be selected such that the PLL output frequency
