50_kHz_MEACHAM_BRIDGE
Crystal osyillator using Meacham bridge requires no transformers for producing low-distortion sine-wave output. Quartz crystal should be cut for operation in series-resonant mode. With minor modifications, same circuit can be used for 100- and 200-kHz crystals. By adding single-transistor stage, oscillator can be used as clock generator for TTL circuits.-K. J. Peter, Stable Low-Distortion Bridge Oscillator, EDN|EEE Magazine, Nov. 15, 1971, p 50-51.
