Description

The SM5009AN1S is a crystal oscillator module IC that belongs to the SM5009 series and is designed to limit oscillator-stage current by incorporating a low crystal current type oscillating circuit. This results in a lower crystal current compared to other similar products. It has excellent frequency response and feedback resistor built-in, allowing it to realize stable fundamental oscillation up to 40MHz just by connecting the crystal. It is suitable for use in SMD type crystal oscillators that use a strip-shaped crystal blank.
