Daughter card for MCU based CNC controllers
Hex-Inverting Schmitt Trigger-based oscillator bank. Three of the sections of the CD40106 can be used either in free-running mode or with so-called hard-sync. The synchronizable sections are at higher frequency so as to be modulated by the lower frequency square waves generated by the first three sections.
Square waves with a standard 50% duty cycle are output.
