Hello i am trying to build a Square wave generator for a step motor and i use a xr-2206 chip to set the frequency. The problem i have is that when i set it higher then 100kHZ the signal gets useless (looks like a sharkfin) and i can not use it. The scheme i use is figure 11 on this page and i use a 1000ρF timing capacitor.
