3.1.4 External clock sources

A 25 MHz oscillator is used as the primary clock source for the PLLs to generate the clock for CPU, BUS,

and high-speed interfaces. For fractional PLLs, the 25 MHz clock from the oscillator can be directly used

as the PLL reference clock.

A 27 MHz oscillator is used as the reference clock for HDMI PHY. Also it can be used as the alternative

source for the fractional PLLs.

A 32 kHz clock input pin is used as the RTC clock source. It is expected to be supplied by an external

32.768 kHz oscillator. When an external RTC clock input is not present, the 32 kHz clock for internal logic

is generated by the 25 MHz oscillator. The frequency of the internal 32 kHz clock will be 31.25 kHz.

Two pairs of differential clock inputs, named as CLK1P and CLK1N, can be used as the reference clock

for the PLL. This is mainly used for a high-speed clock input during testing.

Four clock inputs to the CCM from normal GPIO pads via IOMUX can be used as the clock sources in the

CCM.

Table 8 shows the interface frequency requirements.

Applying the maximum voltage results in maximum power consumption and heat generation. A voltage set point = (Vmin + the supply

tolerance) is recommended. This result in an optimized power/speed ratio.
