Ethernet interface characteristics

Unless otherwise specified, the parameters given in Table 210, Table 211 and Table 212 for

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

frcc_c_ck frequency and VDD supply voltage conditions summarized in Table 120: General

operating conditions, with the following configuration:



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



Capacitive load CL=20 pF



Measurement points are done at CMOS levels: 0.5VDD



IO Compensation cell activated.



HSLV activated when VDD ≤ 2.7 V



VOS level set to VOS1

Refer to Section 7.3.15: I/O port characteristics for more details on the input/output

characteristics:
