Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions above those indicated in the operational sections
of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product
reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
Note: This matches the IEEE requirement in the 100Base-X standard definition for the code-bit-timer (24.2.3.4)
which is more stringent than the basic media independent interface (MII) specification for the TX_CLK of
±100ppm (22.2.2.1).
