POWER SUPPLY RECOMMENDATIONS

POWER-UP SEQUENCE

The recommended power-up sequence for the ADV7613 is to

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

Hold the RESET line low for at least 5 ms after the supplies have

powered up. Allow a minimum additional 5 ms before carrying

Alternatively, power up the ADV7613 by asserting all supplies

simultaneously. In this case, take care while the supplies are

being established to ensure that a lower voltage supply does not

go above a higher voltage supply level. Hold the RESET line low

for at least 5 ms after the supplies have powered up. Allow a

transaction.

as long as a higher rated supply (for example, TVDD/DVDDIO)

does not fall to a voltage level less than a lower rated supply (for

specifications are followed.
