System Level Interfaces
The following figures illustrate the high-level system connections to the KSZ9692MPB/KSZ9692XPB. Note that these
figures are for illustration purpose only. The system designer must refer to Evaluation Design Kit for actual circuit
implementation.
Figure 14. Reset Circuit
Figure 15. Power and Clocks
According to some DDR device manufacturer’s electrical specification, DDR400 devices operating at 200 MHz require a
2.6V power supply. DDR333 and DDR266 devices require 2.5V power supply. Power to the SoC DDR Memory Controller
must be based on DDR device power requirement specification.
