Electrical characteristics

Figure 46. ULPI timing diagram

Ethernet characteristics

Unless otherwise specified, the parameters given in Table 64, Table 65 and Table 66 for

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

frequency summarized in Table 14 and VDD supply voltage conditions summarized in

Table 63, with the following configuration:

•

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

•

Capacitive load C = 30 pF

•

Measurement points are done at CMOS levels: 0.5VDD.

Refer to Section 5.3.16: I/O port characteristics for more details on the input/output

characteristics.

1. Guaranteed by design, not tested in production.
