283_MHz_THIRD_OVERTONE_TTL

Published:2009/7/6 0:55:00 Author:May | From:SeekIC

Third-over-tone crystal oscillator uses 74S00 Schottky TTL quad NAND gates acting as oscillator and output buffer to increase output amplitude. Output swing is from about 0.4 to 3.5 V P-P, as required for TTL. No inductors are required.-C. Hall, Overtone Crystal Oscillators Without Inductors, Ham Radio, April 1978, p 50-51.
