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 resistor Rfo, a favorable 3rd overtone oscillation can be realized with a few external components. The oscillator circuit characteristics are optimized for a 3rd overtone oscillation by round blank. They also feature a built-in output buffer with high output drive capability and are available in miniature 6-pin package, making them ideal as DIP-type crystal oscillators.
