Ethernet characteristics

Unless otherwise specified, the parameters given in Table 113, Table 114 and Table 115 for

SMI, RMII and MII are derived from tests performed under the ambient temperature,

frcc_c_ck frequency summarized in Table 23: General operating conditions, with the following

configuration:

•

Output speed is set to OSPEEDRy[1:0] = 10

•

Capacitive load C = 20 pF

•

Measurement points are done at CMOS levels: 0.5VDD.

Refer to Section 6.3.15: I/O port characteristics for more details on the input/output

characteristics.

Table 113 gives the list of Ethernet MAC signals for the SMI and Figure 60 shows the

corresponding timing diagram.
