7 series GTX - What is the power consumption of the eye scan circuit?

Description

What is the power consumption of the eye scan circuit in 7 series GTX, under the following conditions:

  • powered off
  • powered, but not used
  • powered and used

Solution

The difference between powered off (PMA_RSV2[5] = 0) and on (PMA_RSV2[5] = 1) is ~20mA on MGTAVCC and ~2mA on MGTAVTT per channel.
 
There is no measurable difference between the eye scan running or not running (PMA_RSV2[5] = 1).
