SIMPLE_TTL_CRYSTAL_OSCILLATOR

Published:2009/6/24 21:25:00 Author:May | From:SeekIC

Circuit NotesThis simple and cheap crystal oscillator comprises one third of a 7404, four resistors and a crystal. The inverters are biased into their linear regions by RI to R4, and the crystal provides the feedback. Oscillation can only occur at the crystals fundamental frequency.
