POWER SUPPLY RECOMMENDATION
POWER-UP SEQUENCE
Adhere to the absolute maximum ratings at all times during
power-up (see Table 6). The power-up sequence for the
ADV7481 is as follows:
1.
Assert RESET (pull the pin low).
2.
Power up the 3.3 V supplies (DVDDIO and TVDD). These
supplies must be powered up simultaneously.
3.
Power up the 1.8 V supplies (DVDD, CVDD, PVDD, MVDD, and
AVDD). These supplies must be powered up simultaneously.
4.
RESET can be deasserted (pulled high) 5 ms after all
supplies are fully powered up.
5.
After all power supplies and the RESET pin are powered up
and stable, wait an additional 5 ms before initiating I2C
communication with the ADV7481.
POWER-DOWN SEQUENCE
The ADV7481 power supplies can be deasserted simultaneously
as long as a higher rated supply (for example, DVDDIO) does not
fall to a voltage level less than a lower rated supply (for example,
DVDD), and the absolute maximum ratings specifications are
followed.
