VOH spec does not apply to signals that are open drain driver. Open drain signals must have an
external pull up resistor.
49.5.18.3 IEEE 1588-2008 Hardware Assist AC Characteristics
The IEEE 1588-2008 Hardware Assist Interface is an edge-dependent interface and has
no critical AC timing requirements.
