MDIO characteristics
Unless otherwise specified, the parameters given in Table 121 are derived from tests performed under the
ambient temperature, fHCLK frequency and VDD supply voltage summarized in Table 22. General operating
conditions, with the following configuration:
•
Output speed is set to OSPEEDRy[1:0] = 10
•
Measurement points are done at CMOS levels: 0.5VDD
•
I/O compensation cell activated.
•
HSLV activated when VDD ≤ 2.7 V
•
VOS level set to VOS0
Note:
At VOS1, the performance can be degraded by up to 5 % compared to VOS0. This is indicated by a footnote
when applicable.
