PRODUCTION DATA.
The digital phase-locked loop (DPLL) provides all interface clocks and functional clocks to the processor of the AM335x device. The AM335x device integrates five different DPLLs—Core DPLL, Per DPLL, LCD DPLL, DDR DPLL, MPU DPLL.
Figure 6-8 shows the power supply connectivity implemented in the AM335x device. Table 6-1 provides the power supply requirements for the DPLL.
