The wave output from the CLK pin looks like this: The datasheet link says “Your require pages is cannot open by blow”: I didn’t even notice that! I added a new link.

Or are you using thethe Intel chip normally driven by an not clokc shown in your schematic? Current and Voltage Relationship for a Capacitor: Just leave it open if you’re not using it. The voltage is also consistent. 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.

When the field is removed, the quartz will clck an electric field as it returns to its previous shape, and this can generate a voltage. Thanks for the heads up. Snowflakes — unique Assembly Presentation. My guess is bigger capacitors on the x1 pin.

I purchased a handful of As and a 15MHz crystal to use with the x1 and x2 outputs. Internal construction of quartz crystal oscillators.

generato I thought the systems clock would be a good place to start. Home Questions Tags Users Unanswered. I am attempting to build my very own computer. 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.

BTW, your reset wiring is incorrect. Those old clock drivers didn’t produce particularly “square” waves cpock and in fact, you wouldn’t want them to, because it would just add to EMI and other bad effects.

After all without a good clock the processor is wasted.

However, it looks like the capacitors are discharging too soon. The most cclock type of piezoelectric resonator used is the quartz crystal See Figure 2so oscillator circuits incorporating them became known as crystal oscillators Figure 1: Consider the RC circuit shown in the figure and answer the following questions: 2884a types of crystal oscillator. Are they 1nF clockk 10 pF?? Post as a guest Name. Seriously, you need to go back and fix all the typos in your part numbers.

You don’t need to have clocl in your circuit, and the waveform will probably look a lot better without it. I 828a fix this as well.

As always, thanks for your help. I have put together my test circuit and it is shown below.
