Opinions on Book about Crystal Oscillators???

Does this proposed book already exist? I think Benjamin Parzen's book, "Design of Crystal and Other Harmonic Oscillators" is pretty good, too bad it can't be updated a bit and placed back in print.

Yes. It's copyright 1983. I bought my copy new many years ago, and paid $44. I've not been very happy with the "print on demand" books I've gotten, VERY expensive, with poor quality printing and binding, and a poor cover.

Looks like it available as "print on demand" as well as several "good" level originals.

Win, Do you recommend it?

I love to cook with wine.      Sometimes I even put it in the food.

I noted that. Does anyone have a membership in UFFC? I only subscribe to JSSC and COMSOC.

Maybe I'll track down one of the "good" grade originals. Looks like ~$150 is the going price.

That all sounds good. "Cuts" should include the new stuff. SCs and the super-thin things. Drive level issues, too. Vibration/G-force might be mentioned.

Some serious example circuits would be good, too. Get somebody (an engineer!) to proof it carefully. I'll do it for a copy or two.

It seems to be available online, with a(n) (IEEE?) membership password required.

Hi Steve,

I understand your reluctance to name the book, but you are perfectly allowed your opinion. People on Amazon do it all the time. I'd love to know if it was one of ours. This kind of feedback is so valuable to me. I don't want my publishing company putting out shoddy books. Perhaps you could e-mail me with the name. tara_book snipped-for-privacy@yahoo.com. If it was one of ours, I'll see to it that you get a copy of another book in the price range at no charge. Regards,

Tara

Something that thoroughly covers the Vittoz oscillators that are becoming popular, would be nice.

Ouch! That's what Amazon has done to the used book market.

A book that sounds very much like what you're proposing is "Crystal Oscillator Circuits" by Robert J. Matthys, published by Wiley in 1983. Another is "Crystal Oscillator Design and Temperature Compensation" by Marvin E. Frerking, Van Nostrand Reinhold 1978. My personal preference leans to Matthys as he's a trifle more practically-oriented and presents a wider range of circuits, but I own both volumes. I'm not familiar with Parzen's book but am curious now and will try to track down a copy. Both Matthys and Frerking are mainly about building oscillators out of parts as opposed to designing transistor-level on-chip circuits.

It's a pity publishers seem so driven to create new titles when perfectly usable volumes often exist on the backlist. Too many recently published books exhibit absolutely horrid editing. One striking example is a thin volume on voltage references I picked up last February (author, exact title, and publisher not disclosed so I don't get sued for slander or libel or whatever). It appears the book was printed as received without no effort to correct the numerous grammatical and typographical errors. On top of that, the information turns out to be more superficial than my quick inspection at a conference booth had led me to believe, and I now thoroughly regret this waste of nearly $60 of my employer's funds.

Possible topics:

1. circuit configuration: Butler, Pierce, Colpitts ...
2. fundamental and overtone modes;
3. low-power oscillators;
4. oscillators using logic gates;
5. precision / temperature control / phase noise / ageing;
6. voltage control / pulling / VCXO;
7. crystal structure / manufacture / mechanical packaging / cuts;
8. electrical model of crystal / equivalent circuit;
9. series & parallel resonance

Hmm. All this stuff is covered elsewhere e.g. RSGB / ARRL Handbooks.

In article , John Larkin wrote: [...]

1.1 Limiting vs AGC 2.1 Unwanted modes 5.1 AVAR

Also hit on "energy trapping" and the effects of nearby modes on the noise spectra.

I think they certainly be mentioned.

A section on specifications, what they mean and likely ranges for them should also be included. Ruling out imposible, or very unlikely, design specifications can save a lot of time.

I'll second that.

Parzen's book from 1983 is over 20 years old today. When it was published, the SC cut was fairly new. It also really needs to have more about noise in it. If an updated work was published, I'd certainly think about buying it.

There are usually only two reasons to design a crystal oscillator: (A) you can't find one good enough or (B) you can't find one cheap enough. It would be nice if the new book had sections on making very good oscillators and making very cheap oscillators.

Hi Tara,

As many others have said there are good books but generally out of print, or restricted to a small group of society members. Many of us are members at IEEE-UFFC but that doesn't address young engineers who may not (yet) be.

Probably it would be best to 'modernize' one of these books and that may require that another author joins in. Especially if the previous author has come of age and is retired.

Such a new edition should contain down-to-earth information including rather mundane topics. An example would be pitfalls when building crystal oscillators with logic chips. A surprising number of engineers does not know about the differences between buffered and unbuffered logic even though that is rather important. Universities don't teach this stuff.

Also, a modern book should teach about clock distribution as well. A crystal oscillator never lives alone, its output usually has to be transported to a myriad of places and often clear across a circuit board. This topic is barely understood by the majority of engineers and has caused numerous initial design failures.

Modernizing an existing volume via a new edition has advantages. There is heritage if the previous edition had visibility and enjoyed praise. This can greatly ease sales. For example, years ago when I saw that a new Radar Handbook edition had come out I immediately placed my order without even a glimpse at it. Because I had the first edition.

Regards, Joerg

I have UFFC membership. A while back I bought the last 50 years of UFFC papers/books for (IIRC) US$100. 20 CD's, and Parzen's book is in the pile. Actually thats why I subscribed to UFFC.

Cheers Terry

...and tell us wether we should ground the can or not!

:)

I doubt the market needs another one. Most of the times I use a quartz and these 27pF to GND. Then a lot more seldom when no oscillator is provided, I take a cristal oscillator in a DIP8 or DIP14 case. Now if an application demanded that I built my own oscillator, then I'd refer to the application notes of the various quartz manufacturers.
