With high speed signals, we need to maintain the impedance of the line (characteristic impedance) to be of the same value throughout the line. This is needed to prevent signal reflection that causes signal distortion. If the line have 90 degree routing, it just means that there is an extra...
Can anyone help me on how to do a derating analysis for all the tantalum capacitors in an existing circuit?
Voltage, current, temperature? where would I look at the values I needed. Thank you.
I'm currently using an old flash memory and I needed to replace it by a new one. I need to check whether the replacement I will pick will resort to software revision which I want to evade. The old flash memory doesn't support common flash interface. How will I verify that the new flash will...

Davestew,
You've already answered your question. Different protocols are made so that they cannot interfere with others means that you cannot communicate zigbee to wlan and vice versa.

Can someone explain to me the difference between normal I2S & I2S TDM? or any document that can explain the I2S TDM functionality. I want to know the disadvantage of using I2S TDM instead of the normal I2S. Also, explanation on the frame, slots, bit rate of both. Thank you.
Autorouting is usable if there are no or just few critical lines in your board. Autorouting saves routing time but still manual routing will bring out better results than doing autorouting unless the person doesn't know the fundamentals of PCB design.
Assuming you are using a processor and memories in your board. You can estimate the minimum number of layers by checking on how many layers are needed to fan out all of the signals in the processor, after determining the minimum number of layers to fan out signals, check if you can satisfy the...
Re: difference between ferrite bead and inductor
Inductor opposes current change & block AC signals. Ferrite beads suppress high frequency signals. Normally you use inductor in any power output especially switching regulators to separate the AC & DC signals then take advantage of opposing the...
We are developing tablet pc connected to a landline telephone with caller ID.
Our problem is that when the charger is connected to the system our caller ID is intermittently working but when the charger is not connected and only the battery is the one supplying the system including the caller...
You're question is too broad, but i think you should start on knowing what your layer stack up you would use. And after routing multilayer board, the only thing that is different would be the layer stack up data, all are same, gerber files, fab notes etc.

A stripline circuit uses a flat strip of metal which is sandwiched between two parallel ground planes -from Wikipedia.
It means that it is better if you can connect 2 parallel ground plane using lots of via. multi layer pcb usually have multiple ground plane. In case of 4 or 6 layer pcb that...
