OVERVIEW
The SM5009 series are crystal oscillator module ICs that incorporate low crystal current type oscillating circuit to limit oscillator-stage current, so that they can reduce crystal current lower than the existing products. Since the oscillating circuit has oscillator capacitors with excellent frequency response and feedback resistor built-in, just connecting crystal realizes stable fundamental oscillation responding up to 40MHz. The SM5009 series are ideal for SMD type crystal oscillator using a strip-shaped crystal blank.
