TPS82084 is not a typical Switching Regulator, it is an integrated module, it doesn't have to be heavily filtered on both sides against 2.4 MHz (its sw frequency). So there is no worry there. My problem, as I asked before, is the USB input which goes directly to efuS Module, NOT regulators, they...
Greetings to all,
I have a question regarding using USB Power Adapter as a Power supply. I am using following module as a part of my HW design: **broken link removed**. It really lacks information in datasheets. The only thing it has on power supply requirements, is that it requires 5V+/-5%...
@Barry, @KlausST and @ Warpspeed,
Thank you all for your posts. It was very helpful.
Well my main concern was that of the meaning of distortion. A signal can be influenced by a cross-talk and its frequency spectrum will contain other than harmonic frequencies. Should in that case these...
" i.e sinusoid with the highest amplitude in the spectrum" - I mean the lowest frequency, not the highest amplitude. Don't know why did I write the highest amplitude.... well in most cases it's so, that fundamental frequency has the highest amplitude, but it's not what qualifies the fundamental...
Good day, everyone.
I have a question regarding understanding of the Total Harmonic Distortion (THD) and why is it a good merit for signal distortion measurement.
With the FOURIER Transform (let’s talk only about DFT) we can decompose any signal into sinusoids of different frequencies, phases...
Hi,
OC Windows 7, 64 bit.
I use the most cheapest normal mouse from Microsoft for 10 euro. =) 2 buttons and one wheel, wired.
As I said, it worked before. I didn't change anything except for changing Altium 10 to 13.3.

Hi all,
I have a problem with Altium. I've been googling for a few days, tried to look in all Altium's preferences - couldn't solve it.
My problem: When I drag a component, I can't flip it (X, Y buttons) or rotate it (space button). I know that you need to click with the left mouse key on the...
thanks anilrock,
I didn't find the primitives, since it was keeping selecting the blank area when I choose "edit/select/outside area", but I decomposed the LDOs into free primitives. And it solved the problem. Although now, it doesn't see it as one component, but only as primitives: pads, vias...
Hi all,
here are 3 pics of the selection sequence. Actually, I'm selecting a blank area to show what happens.
Also I've attached a PCB doc. It's a bit of a mess, since it's my first project with CAD system and DAC3484 has a really bad package where you can fanout only with 3 mil traces and...
anilrock87,
doesn't seem like hidden polygons and 100% not a component text. It's just wherever I click there are 3 elements (LDOs) which show up for selection. If I click on an area where there are some other components, it adds it to the list of choice, but these freakin LDOs are still in the...
Hello everyone,
I have a problem with Altium. When I try to select a component in PCB the area which is highlighted by this component is way broader then the component itself (like half of the screen). It also prevents me from selecting other components, or rather to say, it makes it really...
hello,
I just choose for my project an SPI Flash - M45PE40 – VMW6G. **broken link removed** . It can work with a clock speed of 75MHz, but how much does it take to save a bit of data or to read it? I've looked through the Datasheet and I'm sure that it's somewhere there, but I guess I just...
