Subject: [SI-LIST] BUS LVDS Spec?
SI'ers,
Is there an EIA/TIA spec for BUS LVDS? I did the search engine thing and
visited the EIA/TIA site but did not find a good answer. Most definitions I
found simply refer to EIA/TIA 644 and substitute 50 (or 55) ohms for the
load on the driver instead of the 110 ohms for the basic point-to-point
spec. I found one rather cryptic reference to RS 644 BUS? Anyone have a
clue if there is a controlled industry spec?
Thanks,
Brad Henson
