    I am new for electronics
    I need to generate 4.194 MHZ 0-5V clock signal from the below circuit.
    I got 4.194 MHZ 5V from the circuit but unfortunately this circuit is giving sawtooth wave.
    Please help me anyone to get square wave signal from this circuit.

    What load do you have on pin 4? You may need to buffer the pin 4 voltage.

    Pretty sure that the chip can't go that fast, look at the datasheet for slew rate.

    DigiKey will program a universal clock oscillator module for you for a few bucks. They come with square wave output, TTL or CMOS, with tri-state enable, power-down enable, various stability, etc.

    This is similar to a circuit I have used. There are a lot of these configurations out there. Just look for them.

    I still say that this is the easiest way to go. Just tell DigiKey the frequency when you order, and they will have it at your door in a couple of days for $4...
