POWER SUPPLY SEQUENCING

POWER-UP SEQUENCE

The recommended power-up sequence of the ADV7610 is to

power up the 3.3 V supplies first, followed by the 1.8 V supplies.

Hold reset low while the supplies are powered up.

Alternatively, the ADV7610 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 rise above a higher rated supply level.

POWER-DOWN SEQUENCE

The ADV7610 supplies can be deasserted simultaneously as long as

a higher rated supply does not fall below a lower rated supply.
