Re: Solid Ground plane
Hi ...
Some considerations you need to keep in mind:
- What the frequency of analog parts?
- Is there any audio part ?
- What the frequency, rise and fall times of digital ?
Keep audio plane separated of others, in most cases some switching noise are audible and they...
Thanks nagaup3 ... very usefull answer and tip. You helped a lot.
alex_epds ... go to a dummies forum or go joking in another place, please.

what is error 302 in allegro
Hello all,
I received a package of files that was archived in Allegro PCB Studio 15.51.
When I'd tried to link HDL and BRD file I got a lot of errors. To solve some errors, I open PCB file and export libs, associate simulation models and export logic w/...
Look at this article, it's from Analog Devices Tech Journal (Analog Dialog), Sept/2005
It was wrote using Op Amps in examples, but you can use the same principle to digital ICs and mainly at high speeds.

Try Hakko (www.hakko.com) I think its one of the best. If you have low budget, mainly if you use it at home, there are some "similar" vendors (best known as copy). Some of these are very good tooling. Just two advises:
- try to replace the iron tips for Hakko original (they suite very well in...
Re: Hierarchy Design..
I agree with all the comments before and add one more advantage. Is easier to produce modules (schematic and pcb) and reuse them later (or in other project).
In Allegro-Concept HDL, for instance, is possible to create a part of you hierarchy and route it. As you put you...
back annotate allegro
If I use a reference PCB, with some parts of circuit pre-routed. And start to produce the schematic from scratching (in Orcad), is it possible to get all ref designators from my pcb file (Allegro brd, in this case) ?
If not, how could I reuse the critical parts of this...
Re: MPEG2-transport stream
Hello imman,
1 seg tuner are you talking about ISBD-T oder DMB-T/H ? Or other standard (i don't know DVB) ?
Please specify better maybe more people could help you ...

Hi Mikes ...
Why did you not consider to use a Microcontroler instead of a CPLD ? You could use uC to acquire signals and it could transmit to PC via RS232 or USB interface (more expensive).
Maybe you have to use a simple combinational logic or a high I/O uC. Anyway if you need to use a...
I have tried but neither IC5033 for Linux or for Solaris installs on Solaris 10 (x86).
I know I'm not helping but I'll increase statistics :-)

I use Mozilla and put a simbolic link in /usr/bin to my mozilla files. Try ln -s [your mozilla bin file] /usr/bin/netscape.
Be sure that /usr/bin is in higher position that you netscape dir in $path.
You could make a alias to netscape. In RedHat 9 this works.
Good luck.

I suggest Koa Speer - **broken link removed**. I'd worked with this for a long time and quality is ok. Look at datasheets and footprints you a intersting and if you want ask for samples (on line).
Best regards,
Renato
Just to add some layout sw to list : Microwind, LASI and Magic.
For the first two, there are books in upload/download section. And I think all of these are free tools ...

What is the frequency of your crystal ? If you are these crystal to RTC of your uC (32768Hz or same magnitude) don't worry about changes do transistor. Temperature could afect you clock more than others factors.
Anyway, I sugest you use an operational amp or a diferential working as...
Xscale development tools
hello all,
I'm a newbie in XScale Development and need some help about tooling to Programing. I have a development board and need software to program it.
Looking for in Interne I found some tooling to buy:
RealView Dev Kit for Intel XScale
RealView Multi-ICE...
