11 / 20 page Data Sheet ADV7612 Rev. D | Page 11 of 20 POWER SUPPLY SEQUENCING POWER-UP SEQUENCE The recommended power-up sequence of the ADV7612 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 ADV7612 may 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. POWER-DOWN SEQUENCE The ADV7612 supplies may be de-asserted simultaneously as long as a higher rated supply does not go below a lower rated supply. 3.3V 1.8V 3.3V SUPPLIES 1.8V SUPPLIES 1.8V SUPPLIES POWER-UP 3.3V SUPPLIES POWER-UP Figure 7.
