Power Domains

6.7
All power domains of the ADV7511W operate off of 1.8 volts, with the exception of the DVDD_3V which is 3.3 volts.
It is recommended that the ADV7511W has its own designated 1.8V linear regulator and that the PVDD, AVDD and
DVDD PCB power domains be segregated using inductors as illustrated in ▶ Figure 21. More detailed
recommendations for the PCB can be found in section ▶ Section 7:.
