CONFIGURATIONS

Multiple Backplane architectures are supported using EEC1005 that are configured by firmware based on an analog

value sampled at one of EEC1005 input ADC pin (Config Pin) at startup. Table 3-1, “EEC1005 Configuration Select”

provides the complete list of Configurations selectable based on the analog value on CONFIG_PIN. The analog value

can be set by a resistor divider network as in Figure 3-1, the values of the resistors are user defined.The configuration

is fixed for a Backplane and is not runtime modified. The recommendations on the resistor values are provided in

Table 3-2, “Recommended Resistor Values,” on page 9.
