Digital designs often need multiple clock domains. I once heard of a design that had more than 10 clock domains on a very large FPGA.
One case I have seen of needing multiple clock domains was when I had to use a DDR3 controller in Platform Designer for a design that targeted Intel FPGA.
One...
Actually I am creating a PCB for the sake of it i.e learn PCB design. So, there are no actual requirements other than that I must make it as much efficient learning experience as possible.
I am creating my first FPGA PCB. It needs clock source.
When I went to Mouser website looking for it, it gave me this list of options contained in the image_1 attached.
When I went to RS website looking for it, it gave me list of options contained in the image_2 attached.
I am basically...
Yes the questions have been answered. There are certain things that I know which I am not sure if they are correct or not which goes through correction with new information. At this time, I am not looking into the subject of PDN in detail although I have realized that it is essential to have a...
I have designed 2 layer boards in Eagle PCB in the past some years ago. Last year I designed another simple PCB with two layers in Altium Designer. In both cases the design did not use anything except through hole package ICs and some SMD resistors and capacitors.
I want to move to the next...
I am trying to learn about high speed PCB design. My dream hobby project is to design an FPGA board conneced to DDR3 RAM. This is where the question come from.
The part of tracks having higher impedance than planes is quite important one. Anyway, if you know of any PCB designs that are done...
Yes, it seems current requirement is the only thing that matters here and there is a lot of option available. The same idea applies to the PCB tracks. In any case, as an answer, some specific value would be quite helpful.
I am studying PCB design and this question came up. I have found answers elsewhere. From what I have learnt, a human hair thick PCB track can carry around 1 Amp without significant temperature rise. So it is down to the person how wide they want to make the tracks. Thinner tracks are better...
For high speed board design, having dedicated GND planes that are all linked together using stitching vias (to reduce impedance for return path) is essential. However, it is not clear why one would need a whole dedicated power plane in the PCB stack up.
Power can be delivered in the same layer...
