Use Of Crystal Oscillator In Microcontroller

This was the voltage chosen for the original TTL family. I'm not sure of the exact reason. It's possible that some previous logic families used 5V, but then there would still be the question for that family. It was undoubtedly a tradeoff between power consumption, reliable switching operation, and noise margins. Or perhaps it's more like the reason that railroad tracks are separated by the width that they are (see ).JohnIn summary, our decision to use 11.0592 MHz crystals in micro-controllers is indirectly based on the natural frequency of human hearing and speech characteristics - which is in a way similar to the solid rocket boosters having their diameters based on the width of two horses asses.
