Universal HF/VHF crystal oscillator with 4 crystal quartz switching possibility
This is my attempt to make universal low noise switching oscillator for use with mine HF/VHF SDR projects or high frequency reference oscillator for DDS IC like AD9850/AD9851...... Oscillator realization is very easy, simple and repetitive and I attached a lot of simulation diagrams.
