Maxim!!!!!!!!

Didn't someone say to never use Maxim? I wish I'd listened. I'm working on a little project using their DS1077 clock generator IC, and have been tearing my hair out for a day trying to figure out why the board isn't working properly. It turns out from searching the web that a lot of people have this problem - I found a forum post by a fellow who was in contact with Maxim who said you have to write settings via I2C to the chip in a specific non intuitive way or it doesn't function properly. Of course, not mentioned in the datasheet at all. Also certain pins seem to have weird undocumented functions that also aren't mentioned.



Unfortunately. it's like the datasheet is someone's fantasy of how the part should work, while the actual part has so many weird quirks as to make the it almost unusable. Unless I can get in contact with someone who has working C code I'm going to have to hope some Maxim engineer can go over my code line by line to see what I'm doing wrong.


Someone? Practically everyone!

And then one fine day insult is added to injury. When the chip goes unobtanium. A quick glance at the available quantities at distributors is ... ahm ... a bit concerning.

Reminds me of the complaint about a restaurant. "The food is bad, and the portions are so small!"

About 20 years ago my wife brought a large and very decorative menu from a business trip to Hungary. So nice that we framed it and hung if in the dining area for a while. Very fancy restaurant. "So what did you eat?" (not that I could read any of that) ... "Cured boar, because everything else on that menu was unavailable that day, and on all other days".

I spent a month in Moscow, in the later years of the USSR. In a restaurant, you'd look at a menu and order something, and the waiter would say "no, not today." So you'd keep trying. They always had the canned-crab salad. My Russian companion would pull the waiter off to the side and say "This is a very important American Capitalist, and he wants the stuffed cabbage rolls." Then they'd do it.

Sometimes they had no beer. I repeat: NO BEER.

And if you eat the salad there is a chance you may need a potty, badly, within 5min reach at all times for the next few days.

But mostly likely they had Vodka. My wife asked for a glass of water on a flight, could have been Polskie Linie Lotnicze. "Sorry, we don't have water, we're out. But I'll bring you Vodka". The stewardess brought a regular size water glass filled to almost half. Well, at least it looked like water. Na'sdarovje :-)

Well, they once told me "vodka" means "water".

So does whiskey. Phonetically it is the Gaelic word "uisge" which means water.

The DS chips are from Dallas Semiconductor. I would have never bought that s***ty company, but I never had the corner office at Maxim either.

Every acquisition Maxim made other than buying fabs turned out to be a waste of money. [Buying old fabs turned out to be great, except for the Tektronix deal, which was about break even.] I often thought it might be a poison pill strategy. That is, buy some s***ty company so that you are less likely as a take over target. Some of the garbage companies they bought never brought a part to market.

Gifford had this notion that engineers are engineers, so you buy a company and you get more engineers. The trouble with that theory is they are not Silicon Valley engineers. You get what you pay for.

Dallas wrote their datasheets. What can I say. Texas is just a notch above Arizona.

Don't forget that Maxim's customer service is unparalleled.

Amazing what we lean on sci.electronics, I will be wary of Maxim now! I first started contributing to sci.electronics in 1996, had a break, then tried to rejoin it a couple of years ago, there was so much spam (selling trainers etc ), I could not use it with my newsreader (Google Groups). As it is all high quality postings, I am back!

Lyn

Ahh... about those high quality postings. Threads occasionally veer off into (or start with) far off-topic political discussions. Although as Godwin noted, this isn't really unusual.

We do have a resident foul-mouthed trolling sockpuppet, though. You'll figure out who he is pretty quickly. Most just ignore him or simply filter his posts and never see them. Some seem to enjoy the sport of troll-baiting. Each to their own, I guess.

Yes, where is this mythical group with all high quality postings?

Listen to the good stuff, there are some world-class experts here. And some world-class idiots. Take the good, skip over the bad, don't take anything personally.

John Devereux

Please tell us what kind of filter you're using to get only high quality postings-- some kind of lock-in amplifier? ;-)

In any case, welcome back.

Huh? Texas Instruments rarely lets one down when it comes to actual product availability. Maxim, on the other hand ...

I did once talk to a nice guy at Maxim who sampled me 3000 pieces of a MAX9691.
