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.

. • HT and QPI busses are proprietary, so while they may have an impact on the I/O bandwidth, it is unlikely any data will be obtained about them. • It was indicated that LightCounting was the source of data on Slide 12.

This "bridge" could then be sucked into the chip holding the MAC as 1GHz+ I/O busses become available.
