We are working with the AD9889B HDMI Transmitter chip.  There are three 1.8 volt power supplies on this part:  AVDD, DVDD and PVDD.  The documentation recommends running them off of separate supplies but the current requirement is listed as a group.  Would you please try to find the individual supply current requirements for us?  Thank you.

We have an existing design that has noise on the PVDD supply so on the next revision we are planning on using a separate supply for each.
