PRELIMINARY
3.4.3
If the phase alignment function is enabled all PLL output signal and the main divider are
edge synchronized with the PLL clock input. If the selected reference signal is less than
2.048 MHz the edge synchronization resolution depends on the selected external
crystal/oscillator frequency. If the phase alignment function is disabled the PLL output
frequency (49.152 MHz) is edge synchronized with the PLL input frequency and the
main divider output frequencies are edge synchronized with PLL output frequency.
An example of phase alignment functionality is shown in
Phase alignment is required to keep the output signals in phase relative to the input
signals. After reset phase alignment is automatically activated in slave mode and turned
off in master mode.
Note: The phase alignment should be disabled for all reference frequencies
