Clock Generator
Description
Embedded Characteristics
The Clock Generator User Interface is embedded within the Power Management Controller and
is described in
the Clock Generator registers are named CKGR_.
The Clock Generator is made up of:
It provides the following clocks:
• A Low Power 32,768 Hz Slow Clock Oscillator with bypass mode.
• A Low Power RC Oscillator
• A 3 to 20 MHz Crystal or Ceramic Resonator-based Oscillator, which can be bypassed.
• A factory programmed Fast RC Oscillator. 3 output frequencies can be selected: 4, 8 or
• Two 80 to 240 MHz programmable PLL (input from 3 to 32 MHz), capable of providing the
• SLCK, the Slow Clock, which is the only permanent clock within the system.
• MAINCK is the output of the Main Clock Oscillator selection: either the Crystal or Ceramic
• PLLACK is the output of the Divider and 80 to 240 MHz programmable PLL (PLLA).
• PLLBCK is the output of the Divider and 80 to 240 MHz programmable PLL (PLLB).
