    Hi Karthik. Happy Morning. My doubt was that why data is not being fed through synchronizer and directly fed to clock domain B and instead only an enable signal is being fed to syncronizer. When data was single bit it was fed to synchronizer while crossing the clock domains in Toggle syncronizer and 2 Flipflop syncronizer.

    Hey Karthik, In timing diagrams the enable signal is pulse signal. In your explanation you considered that clk A frequency is lower compared to clk B frequency. So the enable pulse in not missed in front of synchronizer. If the clk A frequency is high compared to clk B, then we will miss that pulse in receiving domain. OR is this the limitation of this synchronizer.

    Hey are are you sending multi bit data through a multiplexer? Are u using PISO?

    You don't need a MUX. Just use a DFF with an Enable signal.

    Hello sir, when do we use handshake synchronizer and mux synchronizer?

    • @KarthikVippala
      @KarthikVippala  4 роки тому

      Handshake is used when we want acknowledgement , but actually it depends on specific design requirements whether to use this or other synchronizer.

    Can we generate o/p such as every positive pulse of I/p will stretch by 1 clk pulse then 2 clk pulse and soo on .. please guide

    May I know...why data should not be changed frequently..if it happens,how it will affect the output.if you explain this problem with timing diagram,it would be much easy to understand for me.Thanks for sharing your knowledge😊

    • @KarthikVippala
      @KarthikVippala  4 роки тому +1

      If we change input frequently , then it will interfere with already processing data , so may cause metastability.
