Description
The SM5009AH2S is a crystal oscillator module IC from the SM5009 series. It incorporates a low crystal current type oscillating circuit, which limits the oscillator-stage current and reduces the crystal current compared to existing products. The oscillating circuit features excellent frequency response and a built-in feedback resistor, allowing for stable fundamental oscillation up to 40MHz. This IC is suitable for SMD type crystal oscillator applications that use a strip-shaped crystal blank.
