External LVR Power Delivery
The following power supply requirements apply to designs where the 82573 is supplied
by external voltage regulators. These systems do not use the internal regulator logic
built into the 82573 as described in
3.3V External Supply Voltage Ramp and Sequencing Recommendations
1. Good design practices achieve voltage ramps to within the regulation bands in approximately 20 ms or less.
2. Excessive overshoot can affect long term reliability.
2.5V External Supply Voltage Ramp and Sequencing Recommendations
1. Good design practices achieve voltage ramps to within the regulation bands in approximately 20 ms or less.
2. Excessive overshoot can affect long term reliability.
3. Tantalum capacitors must not be used.
