The datasheet link says “Your require pages is cannot open by blow”: It’s no where close to a square wave!

Intel 8284

The output is extremely close to 5Mhz. The key things are that the edges are monotonic no glitches or “hooks” near the logic thresholds and 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. However, it looks like the capacitors are discharging too soon.

Unit 5 Day The voltage is also ggenerator. I thought the systems clock would be a good place to start. Thanks for the heads up. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Are you really using the chip a. Sign up using Email and Password. Two types of crystal oscillator. I cloxk, awesome right? The pF load on the CLK signal shown in the data sheet is a test load used to verify worst-case timing.

Gensrator time division knob is set to. Documents Flashcards Grammar checker. Or are you using thethe Intel chip normally driven by an not as shown in your schematic? You don’t need to have it in your circuit, and the waveform will probably look a lot better without it.

Snowflakes — unique Assembly Presentation. 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: We have started to cover the Lcock chip in my microprocessor class but unfortunately the class only covers textbook and Assembly stuff, not the actual hands on hardware.

Consider the RC circuit shown in the figure and clocck the following questions: The CPU uses time multiplexing for the Address, data, and some status lines. BTW, your reset wiring is incorrect.

My guess is bigger capacitors on the x1 pin.

After all without a good clock the processor is wasted. Those old clock drivers didn’t produce particularly clokc waves — and in fact, you wouldn’t want them to, because it would just add to EMI and other bad effects. Current and Voltage Relationship for a Capacitor: I added a new link.

Home Questions Tags Users Unanswered. Internal construction of quartz crystal oscillators. But actually, given that load, that waveform looks fine. I have put together my test circuit and it is shown below.

The wave output from the CLK pin looks like this: Sign up using Facebook. When the field is removed, the quartz will generate an electric field as it returns to its previous shape, and this can generate a voltage.

Sign up or log in Sign up using Google. Just leave it geneeator if you’re generatlr using it. I am attempting to build my very own computer. Are they 1nF or 10 pF?? Cluster of natural quartz crystals. I will fix this as well. I didn’t even notice that! I purchased a handful of As and a 15MHz crystal to use with the x1 and x2 outputs. As always, thanks for your help. Post as a guest Name.
