Table 6-1. Oscillator Summary
6.1.1 Internal Oscillators
6.1.1.1 Internal Main Oscillator
In most designs the IMO is the only clock source required, due
to its ±1% accuracy. The IMO operates with no external
components and outputs a stable clock. A factory trim for each
frequency range is stored in the device. With the factory trim,
tolerance varies from ±1% at 3 MHz, up to ±7% at 62 MHz. The
IMO, in conjunction with the PLL, allows generation of CPU and
system clocks up to the device's maximum frequency (see
Phase-Locked
The IMO provides clock outputs at 3, 6, 12, 24, 48, and 62 MHz.

6.1.1.2 Clock Doubler
The clock doubler outputs a clock at twice the frequency of the
input clock. The doubler works for input frequency ranges of 6 to
24 MHz (providing 12 to 48 MHz at the output). It can be
configured to use a clock from the IMO, MHzECO, or the DSI
(external pin). The doubler is typically used to clock the USB.
6.1.1.3 Phase-Locked Loop
The PLL allows low frequency, high accuracy clocks to be
multiplied to higher frequencies. This is a tradeoff between
higher clock frequency and accuracy and, higher power
consumption and increased startup time.
