    I love how I have the same oscilloscope lol. I am basing my cmos alarm clock based on your lessons. I've spent like 100 dollars on chips and buttons since I discovered your channel and I don't regret any of it

    I tried the crystal oscillator circuit and it works. However, every other source shows a pair of feedback capacitors which you have omitted, so although it works, I'm still not sure the circuit is correct.

    Thanks for the video, I seem to be getting a 10hz output using the same circuit as you with a 32768Hz crystal and 330k resistor, I'm not sure why, any help would be appreciated. You also seem to use a different circuit to that used on the CD4060 datasheet?

    • @Ciiads
      @Ciiads 2 года назад

      9:08 asper the video he said 330k resistor, but insted of 330k he used some resistor having colour code brown brown yellow gold as per the colour code that is 110k ohms with a tolerance of 5%. Bingo 👍.
      If you got 10hz you just check and change the crystal that will fix your issue.

    Hello Sir. Very good video. I found some other circuits from internet. But they connected some capacitors and resistors. Different values in different sites. Is this necessary?

    How to get 1hz frequency from other values of crystal oscillator like 25 Mhz, 10 Mhz ,4 Mhz, 8 Mhz , 32.767 Mhz?????Actually I tried with other crystals also and applied your calculation technique but unfortunately did nit get the required result...

    • @EEWave
      @EEWave  4 года назад

      In this case, we can not use 4060. We have to use other counter like ÷5 and ÷10.

  • @pewter5837
    @pewter5837 3 года назад

    A very good explanation but sadly not quite accurate headline. It all relies on the crystal actually oscillating at the stated frequency. But it varies, mostly due to temperature change and age. That's why there are other devices, some quite expensive, such a txco devices(temperature compensated crystal oscillator) which get much closer to '100%' 1 Hz.

    Can you explain why you use a 330K resistor ? Is there any equation or something to figure out the res value? btw the video is great, thank you for your instruction

    • @EEWave
      @EEWave  5 лет назад +2

      Some people say it is a damping resistor which will reduce the chance of damage of the Crystal oscillator. Or some say it is border frequency resistor. If you see the datasheet of IC 4060, then you can find the typical Crystal circuit where they have used a higher valued resistor in the oscillator circuit, and I've taken that circuit. Till now, I don't have any satisfying answer to your question, I'm also searching for the answer.

    This is NOT 100% accurate .. There is missing some capacitors In the oscillator .. Yes 1 hz seems accurate but it’s a dividend signal .. I builded a few of these from this video here and used Them for time base .. Resultat the clock loose 3 seconds a day .. Because the 32768 hz crystal differ with 1 hz ...
    When divided to 1 Hz .. it’s 1/32768 hz wrong ... This oscilloscope is not accurate enought to show 1/32768 hz ... Or in otter words the 1 hz signal is 0,000003052 Hz wrong ..
