POWER SUPPLY RECOMMENDATIONS
POWER-UP SEQUENCE
The recommended power-up sequence for the ADV7619 is to
power up the 3.3 V supplies first, followed by the 1.8 V supplies.
RESET should be held low while the supplies are powered up.
Alternatively, the ADV7619 can be powered up by asserting all
supplies simultaneously. In this case, care must be taken while
the supplies are being established to ensure that a lower rated
supply does not go above a higher rated supply level.
