The voltage input to the DPLLs has a low noise requirement. Board designs should supply these voltage inputs with a low noise LDO to ensure they are isolated from any potential digital switching noise. The TPS65917 and TPS659039 PMIC LDOLN outputs are specifically designed to meet this low noise requirement.
NOTE
For more information about Input Voltage Sources, see Section 6.3DPLLs, DLLs Specifications.
Table 8-4 presents the voltage inputs that supply the DPLLs.
