7.24.1.1 Internal RC oscillator

The Internal RC oscillator (IRC) may be used as the clock source for the watchdog timer,

and/or as the clock that drives the PLL and subsequently the CPU. The nominal IRC

frequency is 4 MHz. The IRC is trimmed to 1 % accuracy.

Upon power-up or any chip reset, the LPC2364/66/68 uses the IRC as the clock source.

Software may later switch to one of the other *ailable clock sources.

7.24.1.2 Main oscillator

The main oscillator can be used as the clock source for the CPU, with or without using the

PLL. The main oscillator operates at frequencies of 1 MHz to 24 MHz. This frequency can

be boosted to a higher frequency, up to the maximum CPU operating frequency, by the

PLL. The oscillator output is called OSCCLK. The clock selected as the PLL input is

PLLCLKIN, and the ARM processor clock frequency is referred to as CCLK elsewhere in

this document. The frequencies of PLLCLKIN and CCLK are the same value unless the

PLL is active and connected. Refer to Section 7.24.2 for additional information.

7.24.1.3 RTC oscillator

The RTC oscillator can be used as the clock source for the RTC and/or the watchdog

timer. Also, the RTC oscillator can be used to drive the PLL and the CPU.

7.24.2 PLL

The PLL accepts an input clock frequency in the range of 31 kHz to 50 MHz. The input

frequency i*ultiplied up to a high frequency, then divided dow*provide the actual

clock used by the CPU and the USB block.

The PLL input, in the range of 32 kHZ to 50 MHz, may initially be divided down by*alue

‘N’, which may be in the range of 1 to 256. This inpu*vision provides a wide range of

output frequencies from the same input frequency
