7 Series HSSIO: MGTAVCC can bias MGTAVTT during power up. Is there a reliability concern?


MGTAVTT can get biased by up to 700mv even when the recommended power up sequence of VCCINT=>MGTAVCC=>MGTAVTT is followed.

Is there a reliability or performance concern?


The small leakage current between MGTAVCC and MGTAVTT can result in MGTAVTT ramping irregularly until MGTAVTT power is switched ON.

There is no reliability concern or performance penalty due to this leakage path.
