ADV7180 ADV7393 Supply Voltages

I have seen a reference design from a co-worker before where he used seperate voltage regulators per power supply voltage on the ADV7180.  For example, one regulator for AVDD, one regulator for DVDD, etc.  Is it possible to use 1 regulator to power all 3.3V pins and 1 regulator for all 1.8V pins?  Does AD have a app notes sheet on this?

 

Thanks,

Scott
