Power Supply Sequencing
Follow the power-up and power-down sequence described in this section to ensure correct
IXF1110 MAC operation. The sequence covers all IXF1110 MAC digital and analog
supplies.
Failure to follow the power-up and power-down sequences will damage the IXF1110 MAC.
Power-Up Sequence
Ensure that the 1.8 V supplies (VDD/AVDD1P8_1/AVDD1P8_2) are applied and stable prior
to the application of the 2.5 V supplies (VDD2/AVDD2P5_1/AVDD2P5_2).
If the 2.5 V supplies (VDD2/AVDD2P5_1/AVDD2P5_2) exceed the 1.8 V
(VDD/AVDD1P8_1/AVDD1P8_2) supplies by more than 2.0 V during power-up, the ESD
structures within the analog I/Os can be damaged.
Power-Down Sequence
The power-down sequence is the reverse of the power-up sequence. Remove the 2.5 V
supplies prior to removing the 1.8 V supplies.
Figure 28
If the 2.5 V supplies (VDD2/AVDD2P5_1/AVDD2P5_2) exceed the 1.8 V
(VDD/AVDD1P8_1/AVDD1P8_2) supplies by more than 2.0 V during power-down, damage
can occur to the ESD structures within the analog I/Os.
