The jitter median describes the point in time where the number of jitter points on either side is approximately equal as opposed
to the averaged time value.

After sending an electrical idle ordered set, the
transmitter must meet all electrical idle specifications
within this time. This is considered a debounce time for
the transmitter to meet electrical idle after transitioning
from L0.
Maximum time to meet all Tx specifications when
transitioning from electrical idle to sending differential
data. This is considered a debounce time for the Tx to
meet all Tx specifications after leaving electrical idle

All transmitters shall be AC coupled. The AC coupling
is required either within the media or within the
transmitting component itself. See Note 8.
This random timeout helps resolve conflicts in crosslink
configuration by eventually resulting in only one
downstream and one upstream port. See Note 7.
