Description

The SM5009AN5 is an IC chip belonging to the crystal oscillator module category, commonly used in electronic devices. The SM5009AN5 incorporates a low crystal current type oscillating circuit to limit the oscillator stage current, reducing crystal current to lower than existing products. The oscillating circuit has oscillator capacitors with excellent frequency response and feedback resistor built-in, which allows for stable fundamental oscillation responding up to 40MHz.
