Electrical Specifications
Table 33 lists the AC specifications for the G/MII interface of the dual GigE Controller. For
propagation delays, the AC loads are assumed to be transmission lines, so numbers quoted in the
specifications assume driving a 50 Ohm load connected to a voltage source = V_CCIO/2.
