180 Khz Square Wave Oscillator question

I want to output a square wave of 180 Khz.
what is the simplest way to achieve this?
Please use layman language as I am not trained in this.

I found this on My question is;
is this capable of 180 Khz and hohw do I establish this output?

The following is pasted from the .pdf.


11 Crystal Controlled Oscillator
A simple yet very stable oscillator can be obtained by using a quartz crystal resonator as the feedback
element. Figure 15 gives a typical circuit diagram of this. This value of R 1
and R 2
are equal so that the
comparator will switch symmetrically about +V CC /2. The RC time constant of R 3
and C 1
is set to be several
times greater than the period of the oscillating frequency, insuring a 50% duty cycle by maintaining a DC
voltage at the inverting input equal to the absolute average of the output waveform.

When specifying the crystal, be sure to order series resonant along with the desired temperature
coefficient and load capacitance to be used.

Try to use 555 IC as Astable Vibrator.
Few Days back i had achieved 161Khz using this.
