POWER SUPPLY DOMAIN CONNECTIONS
One key aspect to ensuring good performance is careful low-noise power management design. Table 108 lists the pin number, the pin
type and name, expected voltage on that pin and a brief description of routing technique together with the block it powers on the chip.
Power supply to the ADRV9001 should be delivered following star configuration where, a separate trace from a common power plane is
used to power each power supply pins. Refer to the user guide section on PCB layout and an evaluation board CAD layout file for details.
