CESIUM_CLOCK_SYNTHESIZER

Crystol 5-Mc oscillator is monitored by natural resonance frequency of cesium (9,192.63184 Mc) to get primary frequency standard. Output signals are 100 kc and 1, 5, 10, and 100 Mc, with accuracy of one port in one billion. Starting with 5 Mc, 9,180 Mc is achieved as harmonic by direct multiplication. Remaining 12.631840 Mc is obtained from 5-Mc source by frequency muhiplication, division, and mixing. Circuit shows input section of synthesizer used for this purpose.-W.A.
