Clock Control Module
Clock Control Module
Overview
Allwinner's A10 has 10 timing or clock sources. 7 Phase Locking Loop's (PLL's), a 24MHz main crystal oscillator, an RC based internal on chip based oscillator and a low-power 32kHz crystal oscillator.
The 24MHz crystal oscillator is mandatory and is responsible for supplying a clock source for the PLL. The 32kHz crystal oscillator is connected only to the RTC to ensure proper time is kept.
Many devices being driving by any of these clocks have often 2 clocks connected to them. One of the clocks drives the chip itself, the other clock matches the bus to whatever it is connected (usually the CPU).
Clock domain
Clock domain | Used module | Speed range | Description |
---|---|---|---|
24MHZ_CLK | Main clock | 24.000 MHz | Core clock source, feeds the PLL and some timers. |
RC_CLK | Timers, key | 32 kHz | Internal 32 kHz source for timers and the RTC. As it is RC based, it is not highly accurate. |
32KHZ_CLK | Timers, key | 32.768 kHz | External 32 kHz source for timers and the RTC. If an accurate 32.768 kHz crystal oscillator is used, this should provide the most accurate timing reference. |
CPU_CLK | CPU | 2 kHz - 1200 MHz | The clock for the CPU clock domain is divided from either the CPU_CLK or the 24MHZ_CLK. |
AHB_CLK | Advanced High-performance Bus clock domain | 8 kHz - 276 MHz | The clock for the AHB clock domain is divided from the CPU_CLK. |
APB_CLK | Advanced Peripherals Bus clock domain | 0.5 kHz - 138 MHz | The clock for the peripherals clock domain is divided from the AHB_CLK. |
SDRAM_CLK | SDRAM clock domain | 0 - 400 MHz | The clock for the SDRAM clock domain is provided by the PLL. |
USB_CLK | USB | 480 MHz | The clock for the USB clock domain is provided by the PLL. |
AUDIO_CLK | A/D and D/A devices | 24.576 MHz or 22.5792 MHz | The clock for the Audio clock domain is provided by the PLL. |
Clock generation
All PLL's are fed from the 24 MHz reference clock.
