Notes:
1. Stresses beyond those listed under Absolute Maximum Ratings might cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those listed under Operating Conditions is not implied.
Exposure to Absolute Maximum Ratings conditions for extended periods of time might affect device reliability.

Notes:
1. MGTHAVCCRX must be powered simultaneously or within T_{HAVCC2HAVCCRX} of MGTHAVCC, but it must not precede MGTHAVCC.
2. MGTHAVCC and MGTHAVCCRX must be powered before MGTHAVCCPLL and MGTHAVTT. This minimum time is defined by
T_{HAVCCRX2HAVCCPLL} and T_{HAVCCRX2HAVTT}.
