Ultimately the chips will land on PC boards with switching power supplies, clock distribution, high-frequency I/O busses, and imperfections that will make layout challenging.

Busses will depart the hotel at 6:30pm, all attendees to be in the lobby by 6:15pm. 5.

This suggestion emanates from my view of electrical serial busses being the functional equivalent of parallel busses and having a BER of 0, not 10E^-12.

Memory busses (to my knowledge) usually carry a number of bits that is a power of two.

Examples of implementation might be backplane busses in modular hubs, or chaining cables in stacks of bridges/switches.

We may need to be more explicit by stating relays fixed in taxis, trains, busses etc.

This is (I believe) a bussed device so things such as power direction can get confusing.

This does not mean we can disregard busses, but it says that the spurious issues of "all ones" or "all zeroes" can be disregarded from an emissions perspective.

In actuality, many of the XGXS devices being designed are already being implemented with the option of bypassing the 8b/10b encoders giving the parallel busses 10bits per channel plus clock anyway, so the LVDS approach compares to 42 pins on the parallel side of the SERDES anyway in many cases.

Eventually UL was able to make some general assumptions about these busses being LPS when the IEEE and USB specifications were modified to specifically mention the need for them to be LPS, e.g., 4.2.2.7 of IEEE 1394a.

Whether registers otherwise holding floating-point values are overloaded for this purpose or new register space (& busses) are created specifically for this task, the cost is non-trivial.
