The XC2165 series of low-voltage crystal oscillator ICs are CMOS ICs that operate from a supply voltage range of 1.5V to 3.6V with built-in crystal oscillator and divider circuits. The output can be selected from any one of the following values for f0: f0/1, f0/2, f0/4, f0/8. With oscillation capacitors and a feedback resistor built-in, it is possible to configure a stable fundamental oscillator using only an external crystal. In stand-by mode, oscillation stops completely and output pin Q0 becomes in the state of high impedance. The XC2165 series are integrated into SOT-26 packages. The series is also available in chip form.
This datasheet describes the XC2165 series CMOS ICs designed for low‑voltage crystal oscillator use. It details the operating voltage range, built‑in crystal and divider circuits, selectable output division ratios, and standby behavior where the output pin enters high‑impedance.
The document includes pin assignments, package dimensions (SOT‑26, 800×1200 µm), electrical parameters such as rise/fall times, duty cycle, and current consumption, as well as ordering information and marking rules for the product series.
