T1040 rise and fall times for 3.3V

In the T1040 datasheet, LVDD/L1VDD can be powered at 3.3V. However, in section 3.6.4 of the same datasheet, the Gb Ethernet reference clock parameters are only specified for IO voltages of 1.8 and 2.5V.  Table 18 has rise and fall time specs that are only given for 1.8 and 2.5V. Is there a spec floating around somewhere that gives the required max rise/fall times for 3.3V IO voltage?
