High-Speed Digital Design is now in it's
15th printing(!). Over the years, alert
readers from all over the world have taken
the time to write in about problems and
errors they've spotted. Here is the complete
list of all errata that has been found.
To use the errata listing it helps to know
which version (printing) of the book you
have. On page iv (the page facing the first
page of the table of contents) near the
bottom, just above the ISBN number, you will
see a row of numbers in backwards order. The
smallest number on this list is your version
number. For example, if the list shows "10 9
8 7", then your book is from the 7th
printing.
The first column of the errata listing shows
the printing of the book in which we have
confirmed each correction has been made. For
example, I have confirmed that the errata
item on page 146 was corrected by the 7th
printing. If your book is from the 7th or
later printing you need not check your book
for that particular correction -- it's
already been made. That particular
correction may have been made in an earlier
printing (Prentice Hall does not keep
records of which correction was placed in
which printing), but we know it was
incorporated at least into the 7th (I know
because I obtained a 7th-printing book and
checked it).
I hope this listing helps you to get the
most out of your book.

Replace both paragraphs in section 5.7.6
with the following:
"A series terminator extinguishes
reverse coupled crosstalk at the near
end. An end terminator attenuates the
returning reflection of the main signal,
the reverse coupling from which would be
again pointed toward the far end. Using
both terminators eliminates both sources
of reverse coupling noise, improving
overall crosstalk considerably."
"The reduced coupling gained by
combining series and end terminations
lets us route parallel bus traces closer
than would otherwise be practical." |

plating shop adjusts its equipment and

The following information comes from
Robert Canright, of Richardson, TX. Mr.
Canright traced my references for
stripline impedance, which I found in
Harlan Howe’s book, all the way back to
the original source papers by Seymour
Cohn. In Mr. Cohn’s paper, he found a
typographical error which was duplicated
in Howe’s manuscript and, unfortunately,
found its way into my text.
The net effect of this error is to
change the stripline impedance formulas
by as much as 2% in cases where t/w
approaches 0.25. If you remain in the
region of guaranteed accuracy, (t/w <
0.11) the results are affected by only
1/2 of one percent. Mr. Canright points
out that in many modern designs, the
ratio t/w can easily exceed 0.25.The
equation for ZSTR_K1(w,t) should read:
The change to this
equation affects the values of several
terms computed on page 439, the correct
values appear
