I am looking at a fast 'square wave' that I've generated with a crystal at 23+ MHz, and divided down with two binary counters. The wave is not very square, but square enough to work as a clock I think. I am curious why, once per period, the wave will fall off into negative voltage (as seen on the oscilloscope) before coming back up. This happens at the falling edge of the waveform. So peak to peak becomes something like 7.6V, when the circuit input voltage is 5V.
Thanks
