PIC24FJ256GB110 FAMILY
7.5
Because of the timing requirements imposed by USB,
an internal clock of 48 MHz is required at all times while
the USB module is enabled. Since this is well beyond
the maximum CPU clock speed, a method is provided
to internally generate both the USB and system clocks
from a single oscillator source. PIC24FJ256GB110
family devices use the same clock structure as other
PIC24FJ devices, but include a two-branch PLL system
to generate the two clock signals.
The USB PLL block is shown in Figure 7-2. In this
system, the input from the primary oscillator is divided
down by a PLL prescaler to generate a 4 MHz output.
This is used to drive an on-chip 96 MHz PLL frequency
multiplier to drive the two clock branches. One branch
uses a fixed divide-by-2 frequency divider to generate
the 48 MHz USB clock. The other branch uses a fixed
divide-by-3 frequency divider and configurable PLL
prescaler/divider to generate a range of system clock
frequencies. The CPDIV bits select the system clock
speed; available clock options are listed in Table 7-2.
The USB PLL prescaler does not automatically sense
the incoming oscillator frequency. The user must man-
ually configure the PLL divider to generate the required
4 MHz output, using the PLLDIV2:PLLDIV0 Configura-
tion bits. This limits the choices for primary oscillator
frequency to a total of 8 possibilities, shown in
Table 7-3.
