... OVERVIEW The SM5023 series are 3rd overtone crystal oscillator module ICs. They feature built-in oscillator capacitors with excellent frequency response. As cutoff frequency can be configured by using an external feedback resis- tor favorable 3rd overtone oscillation can be realized with a few external components. The oscillator cir- fo cuit characteristics are optimized for a 3rd overtone oscillation by round blank ...
