4.11.1
The DELIC clock generator provides all necessary clock signals for the DELIC and
connected clock slave devices. The internal clocks are generated by two on-chip PLLs:
1. A digital controlled oscillator (DCXO) generates a 16.384 MHz clock from an external
2. A PLL multiplies the 16.384 MHz clock to a 61.44 MHz clock.
An overview of the clock signals and a block diagram is shown below.
