Unlike a UNO, an Arduino DUE can easily output a PWM pulse at 200 KHz with a dead time.

I need to obtain 200 kHz from Arduino Uno. I am using Timer0. I have configured it to run in normal mode and the Prescaler is set to clk/8 (the clock frequency of Arduino is 16 MHz). TCNT...
Someone contacted me recently about using an ATMega328 to generate a 200 kHz clock signal for a BBD analog delay chip. I finally had a few minutes today to sit down and ensure.
Understanding the Context
A simple PWM Frequency Generator built with Arduino, allowing users to adjust the output frequency using a button. The current frequency and prescaler are displayed on an LCD.
Since some of you asked to show in detail my variable frequency arduino generator for high voltage power supply, here it is.
Is it possible to generate a PWM signal of 200kHz using the Arduino Nano? I have found examples of generating around ~65kHz by changing the settings of Timer0 using the line:
There are frequency generators which can generate the required waveform like sine wave, saw tooth wave etc. but for normal applications the square wave generation with variable frequency.

Arduino: Generating 200 kHz pulse on Arduino Uno in normal mode Helpful?
The signal generator can be powered simply through the mini-USB cable of the Arduino Nano. It is best done with a power bank, so that there is no accidental ground loop with the apparatus that it.
However, I have intercepted the circuit board on one of the fish finders such that I can inject my own signal (a 200kHz 5V square wave) and have it amplified and sent to the transducer.
