2.2.1 PLL Specification
Fin
100MHz F
A PLL consists of a Voltage Controlled Oscillator (VCO) and a Post Divide (PD)
circuit, as presented in
The frequency from the VCO, F
F
The bit width of N, M, P is 9, 5 and 2 bits respectively. The N, M and P bits are
programmable register bits in the Clock module control registers, PLL0_CTL and
PLL1_CTL. PLL2_CTL does not allow to control the P parameter since it is fixed to
‘1’, i.e. divides F
interface.
Remark: Using a value of 0 for either M or N could lead to undesirable behavior. For
that reason, setting either M or N to 0 will result in a value of 1 being used for both M
and N. Assuming the P value is set to 0, this will result in a PLL output frequency of 27
MHz.
