Ethernet interface characteristics
Unless otherwise specified, the parameters given in Table 212, Table 213 and Table 214 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 121: 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:
1. Guaranteed by characterization results.
Table 212. Dynamics characteristics: Ethernet MAC signals for SMI (1)
