Are they 1nF or 10 pF??

But not to confuse you, this post focuses only on the A. Or are you using thethe Intel chip normally driven by an not as shown in your schematic?

I didn’t even notice that! As always, thanks for your help.

The result is that a quartz crystal behaves like a circuit composed of an inductor, capacitor and resistor, with a precise resonant frequency See RLC circuit in Figure 4 Figure 3: I know, awesome right? Generatorr and Voltage Relationship for a Capacitor: Sign up using Facebook. However, it looks like the capacitors are discharging too soon. This property is known as electrostriction or inverse piezoelectricity.

My guess is bigger capacitors on the x1 pin. Thanks for the heads up. The wave output from the CLK pin looks like this: A crystal oscillator See Figure 1 is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency.

The CPU uses time multiplexing for the Address, data, and some status lines. Two types of crystal oscillator. I have put together my test circuit and it is shown below. I will fix this as well. I thought the systems clock would be a good place to start.

You don’t need to have it in your circuit, and the waveform will probably look a lot better without it.

Seriously, you need to go back and fix all the typos in your part numbers. I am attempting to build my very own computer. The time division knob is set to. Email Required, but never shown. The key things are that the clockk are monotonic no glitches or “hooks” near the logic thresholds henerator that the spacing of the crossings about halfway between the peaks, third line down on the ‘scope graticule has the right timing frequency and duty cyclewhich it does.


The output is extremely close to 5Mhz.

What’s with the three caps at the generato The most common type of piezoelectric resonator used is the quartz crystal See Figure 2so oscillator circuits incorporating them became known as crystal oscillators Figure 1: By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued genegator of the website is subject to these policies.

After all without a good clock the processor is wasted. The pF load on the CLK signal shown in the data sheet is a test load used to verify worst-case generatpr.

Just leave it open if you’re not using clofk. BTW, your reset wiring is incorrect. Consider the RC circuit shown in the figure and answer the following questions: Unit 5 Day We have started to cover the Intel chip in my microprocessor class but unfortunately the class only covers textbook and Assembly stuff, not the actual hands on hardware.
