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:
PLLBCK is the output of the Divider and 60 to 130 MHz programmable PLL (PLLB)
• 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 60 to 130 MHz programmable PLL (input from 3.5 to 20 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 60 to 130 MHz programmable PLL (PLLA)
