27. Clock Generator
27.1
6430D–ATARM–25-Mar-11
Description
The Clock Generator is made up of:
It provides the following clocks:
The Clock Generator User Interface is embedded within the Power Management Controller and
is described in
the Clock Generator registers are named CKGR_.
• A Low Power 32,768 Hz Slow Clock Oscillator with bypass mode
• A Low Power RC Oscillator
• A 3 to 20 MHz Crystal Oscillator, which can be bypassed (12 MHz needed in case of USB)
• A factory programmed Fast RC Oscillator, 3 output frequencies can be selected: 4, 8 or
• A 480 MHz UTMI PLL providing a clock for the USB High Speed Device Controller
• A 96 to 192 MHz programmable PLL (input from 8 to 16 MHz), capable of providing the clock
• SLCK, the Slow Clock, which is the only permanent clock within the system
• MAINCK is the output of the Main Clock Oscillator selection: either Crystal Oscillator or
• PLLACK is the output of the Divider and 96 to 192 MHz programmable PLL (PLLA)
• UPLLCK is the output of the 480 MHz UTMI PLL (UPLL)
12 MHz. By default 4 MHz is selected.
