The TG-3541CE32.7680KXB0 is a built-in 32.768 kHz digitally temperature-compensated crystal oscillator (DTCXO) designed for high-stability timing applications. It operates over a wide supply voltage range from 1.5 V to 5.5 V and across an industrial operating temperature range of -40 °C to +105 °C. This specific 'XB' variant maintains a frequency tolerance of ±5.0 x 10⁻⁶ from -40 °C to +85 °C. With its low current consumption of 1.0 µA typical and high precision in a compact package, it is ideal for real-time clocks, portable electronics, and automotive systems requiring accurate and reliable timing.
