Output timing specifications assume an equivalent test load as illustrated in
The LAN9220 supports the following host cycles:
All timing measurements were verified under the following conditions:
Note: The specified test load used for output timing is dependant on VDDVARIO.

DATASHEET
Test load varies dependent on VDDVARIO:
VDDVARIO = 3.3V ± 300mV: 25pF
VDDVARIO = 2.5V ± 10%: 10pF
VDDVARIO=1.8V ± 10%: 10pF
