1.The value of 10 µs given is a nominal value only. The exact time difference between the application of the 2.5 V analog supply is determined by a number of factors, depending on the power management method used.

NOTE: To avoid damage to the IXF1104 MAC, the TXAV25 supply must not exceed the VDD supply by more than 2 V at any time during the power-up or power-down sequence.

NOTE: The 3.3 V supply (VDD2 and VDD3) can be applied at any point during this sequence.

4.8Pull-Up/Pull-Down Ball Guidelines

The signals shown in Table 20 require the addition of a pull-up or pull-down resistor to the board design for normal operation. Any balls marked as unused (NC) should be unconnected.
