Ok, let's try it the brute force way. You'll need 6 counters, 6 decoders/drivers, and a 6 digit, 7 segment display or 6 individual displays. Add a 1 Hz gate clock, some latches between the counters and decoders/drivers and maybe an input amplifier (depending on your source).
Now for the next...
By dead zone I assume you mean the issue with phase detectors and their operation near zero phase error. From a frequency synthesis view point the only thing I have done with the dead zone is to have an additional circuit monitor the position of the locked edge within the dead zone and apply a...
re: BGA on both sides
Bob,
Well we had some SDRAMs on one side and a power supply on the other. When I did the thermal analysis on the power supply the additional heat from the SDRAMs was not taken into account. I assumed the power supply was being heatsinked by the copper planes, which it...
re: BGA on both sides
Also remember that the thermal dissipation numbers for a part mounted on a pcb assume there are no heat generating parts are mounted below. This has gotten me in trouble a couple of times.

re: BGA on both sides
We often have BGA / QFN as well as other parts placed on both sides of a board without issues. I was worried at first but the assembly house said no problem. It is my understanding that each side is processed individually and when the second side is processed the reflow...
There must be some misunderstanding about what you mean by distortion. My dictionary says:
Electronics. a. An undesired change in the waveform of a signal. b. A consequence of such a change, especially a lack of fidelity in reception or reproduction. Excerpted from The American Heritage®...
They're all used for different purposes so you really can't talk about advantages or disadvantages. If you need to take a particular measurement generally only one instrument will do it well. Here is a brief overview of the different instruments.
An oscilloscope is the most basic and it only...
That statement wrong on a couple of counts. First define "Best Quality". Solid state amplifiers can have a much lower level of distortion that the best tube amps. Tube amps just have distortion that is less offensive to the ear. So if you're after the most accurate reproduction a high quality...
Just some quick format info. The DVI receiver/transmitter would likely be 8 bits per color or 24 bits per pixel. The data bus from the DVI controller is 12 bits so the format is likely R[7:0]G[7:4] and G[3:0]B[7:0]. The two 12 bit data words could come out on consecutive clocks or the the output...
Is the DIP-8 just a plain CMOS oscillator? That is power, ground, output and optionally an output enable? Try searching for Oscillators - Programmable. There are 2 types listed. Of course then you would have to deal with programming it. Some of the larger distributors will program these type of...
I was planning on drawing a nice diagram explaining the issue but since I try and squeeze these posts in at work I don't have time right now. So let me just say a few things. Since all supplies have some output resistance when the load current varies the voltage will also. Draw a schematic...
Using a straight 20MHz and depending on your required baud rate you could have a baud rate error. That error could be small and insignificant or large enough to data errors. The frequencies listed in the tables are for zero frequency error are derived using integer divisors which the PIC must...
Have a question about the Atmel SAM3U series microprocessor specifically the SAM3U4C.
We are trying to use the 12-bit Analog-to-Digital converter (ADC12B) with an external hardware trigger on the AD12BTRG pin (PA2).
With ADC channel 2 enabled (also tried different combinations of enabled...
I don't know of any books but having R-R I/O can be helpful for single supply operation. One example is for current measurement or control where one end of the sense resistor is tied to either ground or power. Having a R-R input stage makes the design a breeze.
In contrast to R-R inputs which...
