RC Oscillator
The RC oscillator is an on-chip free-running clock source generating a 100 MHz clock. It can be used as
a source clock for both on-chip and off-chip resources. When used in conjunction with the Fusion PLL
and CCC circuits, the RC oscillator clock source can be used to generate clocks of varying frequency
and phase.
The Fusion RC oscillator is very accurate at ±1% over commercial and industrial temperature ranges. It
is an automated clock, requiring no setup or configuration by the user. It requires only that the power and
GNDOSC pins be connected; no external components are required. The RC oscillator can be used to
drive either a PLL or another internal signal.
