Figure 5 shows the main clock distribution for the SYSCLK domain and the WSPLL clock domain.
For power saving reasons each clock signal inside the system must be controlled and enabled via a separate bit in the
L3-bus and I
The DAC part of the UDA1380 can operate from 8 to 100 kHz sampling frequency (f
the ADC part can run from 8 to 55 kHz.
