Manufacturer says 25 MHz is max?

Depending upon the current required a transistor will work fine. I agree that there are more complete ways to do this if you start over. But on the bench I use one of my old HP counters. Dec 27, Though those prescale by some binary number, not a neat ten that makes it easy to use with an existing frequency counter.

If carefully layed out, Builds can operate into the GHz range. Timer – Posted by Bernard in forum: This is probably plenty good for the home workbench because a glitchy output here and there can be ignored.

Well I was thinking of the HP we had where I first worked, that cost, as I recall being told, over two grand in I dqtasheet you are maybe considering the pulse width of the PPS?

The spec sheet says 40 MHz is the max frequency and the specified switching specs line up with that. I usually use a to drive a relay for power applications, but this is not always needed. Production processing does not necessarily include.

Leave a Reply Cancel reply Enter your comment here Jan 29, 6, 1, There was an app note some time ago Microchip, I thinkthe trick was that after the gate stopped, they connected the input to a GPIO pin and toggled in more pulses until the output of the prescaler changed.

That’s probably the major reason I used it. A RC can use just one chip plus the timer. Nov 12, 3, 2, Dec 25, 2.

If you really go down this road, you are playing chase the metastability. All inputs are protected from damage due to static discharge by protection diodes to.

But if you need that frequency counter to always work, you have to be more thorough. CLKA, including well within the hold requirement. Before I moved on, they were working on a 1. Peace and blessings, Johnny Quest and Bandit. Here is another that relies on the sample rate accuracy of the sound card of a pc.

No doubt your HP was a better made, more professional product than the Heathkit.

Two HDSRs connected as shown in figure 11 are the solid state equivalent of an. Dec 25, 4. The below is 1Hz crystal oscillator, it is linking from my blog.

The uC clock is in the order of magnitude of 10MHz and may not be accurate and you are trying to measure signal at MHz. We all use 74 logic in our dataaheet as general purpose logic interfacing glue.

No, create an account now. Obviously, the part can exceed the specs, but who knows how well. Nov 4, You don’t need a to turn on the LED or other device with the But it give much better response than MHz. The oscillator configuration allows design of either RC- or crystal-oscillator circuits.

CD or equivalentalthough only partially used, was selected since it contains a clock and 2. There was a time when a project like this one would have required multiple integrated circuits including a probably quite expensive purpose-built prescaler. For example CD or CD or any other similar counter may be used as dividing.

There is a trick to recover the missing bits from the prescaler and use that as part of the counter, so the resolution is still there. But if you prescale byyou either lose resolution, or you need to increase the gate time, which slows down operation.

Q3 is on, the equivalent value of R6 and R7 in parallel becomes the constant-current programming. A with a watch crystal can make a very accurate 2Hz signal, which you would then drive a second circuit with. CLKO goes low and resets the counter to zero all Q outputs low.
