PRODUCTION DATA
The PLLD_VAD, PLLM1_VAD, and PLLM2_VAD power feeding internal PLLs must be derived from an isolated linear regulator with filter as recommended in Section 9.1.2 to minimize the AC noise component.
It is acceptable to derive PLLD_VDD, PLLM1_VDD, PLLM2_VDD, and PLLS_VAD from the same regulator as the core VDDC, but they must be filtered as recommended in the Section 9.1.2.
